EEVblog #708 - Free Energy BULLSHIT!
« on: January 24, 2015, 09:45:48 pm »
Are the laws of physics being bent?
Dave explains why free energy / over unity / quantum vacuum circuits are bullshit. And how to find out what's really happening here by using basic engineering principles.
Can a bunch of toroids, some wire, and a simple circuit boost converter really generate more power than you put in and power 23 LED's for 52 hours?
He goes through the claims and debunks them one-by-one.
Explains how the circuit works and then builds up the circuit and takes some measurements to show that the energy can easily come from the battery and not some quantum vacuum.
This is as much a demonstration of basic ballpark system engineering, calculations, and understand, as it is debunking.

The video in question is here:

Interesting, thanks.
Another 60Hz video? Quality is poor again on my TV.

How can the quality be "poor"? in what way?

When I see/read about "free energy" devices, it's always some kind ovf very complicated circuit and always very low power. If your device produces more energy than it takes, then connect a few of them in series and power a 40W incandescent lightbulb from the single AA battery. That would be impressive.

Not to mention the fact that (in the UK) an AA battery costs approximately 40 pence, and as Dave's debunk vid shows us, delivers a max of about 4WHrs.  Yet, that same 40 pence, currently buys you in the order of 2.5 KWHrs of mains electricity.

By that token, even if this device did posses some physics bending properties (which it doesn't) then it is not "Free energy" whatsoever, and in fact is "extemely expensive" energy!!!

I'm guessing Dave's circuit was more efficient than ManOfStone's since ManOfStone used a Darlington.  You definitely don't want a Darlington--with its high Vce--for this circuit.

If you're going to build such a circuit and you are already using a ferrite core then you might as well wind the core as a transformer and use the Joule thief circuit.  This will eliminate the PNP transistor.

Hi Dave,

thanks for your rant  >:D. Hilarious!  ;D

I love how you explain things, there's nothing like it here in good old Germany  :=\ :=\

One thing, though: If you just feed a constant current through these LED's without all the
fancy circuit, the power source would surely be earlier depleted than with these spikes at
91 kHz?

Calculating the amount of power contained under these curves should show that a lot
less is needed to light those LED's at 91 kHz, which no eye can follow and which seens
like constant lighting.

Gosh, how I love electronics and high frequency experiments. I have set up quite a nice
little bench here for my radio amateur equipment...   ^-^ ^-^

Keep up  the good works down under, Dave!  :-+ :-+ :-+ :-+ :-+

Yeah when Dave mentioned it was a Darlington i was somewhat surprised the original circuit worked. If it was half as efficient as Dave's, it's around 25% or so?

And modern high efficiency red LEDs are unbelievably bright. 20mA is like 'clearly visible outside at noon in direct sun' power levels on those.

I suspect that the "original" circuit oscilates somewhat faster than Daves, as it has a lower inductance value.  Hence it will transfer more energy to the LEDs than Daves, and hence draw more input current.....

And like i said, even if it somehow breaks all known laws, the inventor is just "generating" energy that costs several thousands of times more per KWhr than the electricity you can just get from the socket in your house....

That's an entirely different argument to what is being discussed here.
I might actually do a video on this, as I have access to a way to accurately capture and measure true light output.

As free energy contraptions go, this one was nice and simple so it was fairly straightforward to analyze.  However, there are some "inventors" in this space that build amazingly elaborate contraptions, such as this guy:

  https://www.youtube.com/user/PMMG4HYBRID

I wouldn't even know where to start taking some of his mechanisms apart for analysis.  I have to applaud his ability to build complex-looking electromechanical devices.  If he was just selling them as artwork, I'd be impressed.   But, of course, it's all to prove he's unlocked some sort of miraculous source of energy.  Sigh...  One common threads I've noticed with many of these guys is to misunderstand voltage and current.  This leads them to think that an increase in voltage is an increase in total energy.  At least, that's how it seems to me that he explains how his devices work.

Damn, people should learn that "free energy" is bullshit, there's nothing wrong with accepting that you have been proven wrong with real experiments and math.
Sadly, there are plenty of nutjobs who buy into the free energy bullshit.

I am running a yellow LED at 900uA, and there it is pretty bright for an indicator. It is replacing a neon lamp as a power indicator, using about the same resistance as the original lamp. Green LED next to it is running at just over 1mA, and it is bright as well.

I ran some at 5mA, and they were bright enough to see in daylight, and at night were usable as a night light. You could play shadow puppets on the opposing wall with the light from the single red LED power indicator.

I remember this basic circuit from my apprentice days.  If you replace the inductor and LEDs with a small loudspeaker and adjust the component values then you have a simple audio tone generator useful for all sorts of applications.  A resistor in series with the capacitor makes the on-time more predictable.

The on-time is controlled by the capacitor and its series resistor.  The off time is controlled by the capacitor and the 100k, so varying the 100k varies the frequency without affecting the on time and replacing the 100k with a potentiometer makes a simple variable tone generator.

Removing the 100k and connecting a pair of probes makes an audio resistance meter useful for trouble shooting circuits or connecting any sort of resistance based sensor gives it an an audio output.  It can be quite sensitive detecting resistance values in the MegOhm region.

Replacing the potentiometer with an electrolytic capacitor and a series resistor makes a circuit that starts at a high frequency when you switch it on and the frequency falls like a siren to zero, ie it stops.  I still have a doorbell, sadly no longer in use, which I made using this circuit over forty years ago.  The bell-push simply shorts out the electrolytic.

Of course it's not suitable for any sort of manufactured product because the performance depends on the gain of the two transistors so is highly unpredictable and it always has to be tweaked but it can keep an apprentice happy for hours.

We hadn't heard of 555 timers in those days.

Yep, now "inventor" of this great free energy source should make more powerfull version and send to Dave lab, while he has very nity legendary kilowat meter: Weston Model 310 AC/DC Wattmeter from 1944!  :-DD

Anyway, after a few modifications this bloody circut maybe could be usefull as very simple low power SMPS ?
What do you think if we add 1k resistor between PNP and NPN base (to limit gate current) does it change much switching frequency defined by 100k and 47pF RC which gives about 200kHz from simply calculation and looks like it was in this range in Dave experiment?

Of course we need to remove those crappy LEDs in parallel and put there fast diode like 1N4148 and make galvanic insulated higher voltage source, eg. to switch on 230VAC AC mosfets switch which require very small amout of charge but higher gate voltage 10V-15V...from Solar  PV cell..

Update: Maybe 1k is too big for 1.5Vin and around 100 Ohm could be better....but for 12Vin maybe 1k could be fine?

BUT, in order to debunk strongly held misconceptions it is necessary to eliminate opportunities for the proponents to fire back pointing out the differences between the original circuit and the one you demonstrated with.

No point, I won't change their mind.
I didn't do this video for them, I did it as an interesting going through the motions engineering exercise.

If your intention is to overcome that unsupportable belief then you ought to do everything possible.

You generally can't change deeply held beliefs. In this case the guy has been studying whatever it is for 16 years, he's not going to suddenly admit that it's all bunk and he's wasted 16 years of his life. Most them just double down.

Dave, I also noticed very recently you are using a Brymen multimeter and your Rigol 1054Z scope. Is there a reason for that? Was it just what was at hand nearest the clear bit of the bench at the time? Or is it part of a commercial arrangement?

I've said this countless times. There is no "commercial arrangement" for product placement, either paid or implied, never has been, never will be.
Yes, they were near to hand. They also have the advantage that both are small, and so frame in a crowded shot like this easier.
I like the Brymen, it's cute.

Dave,

Great video, again. I'm a professional systems designer for nearly 20 years now, and I have been following your blog since the beginning.
I also recommend it to colleagues and beginners. It has tons of information and learning opportunity packed in an entertaining presentation.

Much respect also for the, in my view, respectful way you give feedback and comment to those who are completely ignorant or full of …
(solar roadways, grafeen capacitors, free energy etc). That must mean something, as i'm from the Netherlands and apparently regarded as being 'direct'  :)

Keep up the great work in entertaining and teaching the community.

regards,
Bart

But doesn't a lower inductance value also means less energy transfer per oscillation? I have my doubts that a faster oscillator, due to lower inductance, has more power

It's all rather complicated! (which is why SMPS design is not straight forward)  I'm also going to guess that the series resistance of the  OP's inductor is also considerably lower than Daves (being a large copper tube).  Hence, the inductors current at switch off will be significantly higher.  Also, with only 1 turn and a massive core area, the core average magnetic field density will be very low.  We don't know what the core loses of Daves test inductor were, but it's physically a lot smaller, with a much higher field density etc.

Anyway, all this swings and roundabouts is really a way of saying "Unless you use exactly the parts, in exactly the same layout" as the OPs circuit, it's not surprising the input current, output power, and overall efficiency are very different"  ;-)

Great video. Odd how these magic devices always require a power source. Nobody every fires one up and then pulls the battery. Wonder why?  ;D

This guy does...


It was actually featured on a discovery channel show about fake science on youtube.

Interesting video, I didn't expect that a battery would be only discharged by a few percents with a short for a minute.

Recently I found another video (I think he did a Kickstarter project and I read about it somewhere here in the forum, but can't find it anymore) :

The video is really boring, you should not watch it, but the interesting part is from minute 30 to minute 37: He measured with a scope the phase angle of the voltage and the current at the input side of his device, and it was 10.75 V, 1.466 A and 78°, so a power of 10.75 V * 1.466 A * cos(78)=3.277 W. Then he measured the voltage and current at the output (a resistor load) and it was 5.228 W. Obviously it doesn't work, otherwise he would have done the only thing to prove such claims, connecting the output to the input and then the resistors should still get hot, but where is the error in the calculation or the measurements?

I suspect that the "original" circuit oscilates somewhat faster than Daves, as it has a lower inductance value.  Hence it will transfer more energy to the LEDs than Daves, and hence draw more input current....

Free energy crowds go: "He didn't follow the original design and instead used an inductor. Probably after discovering that ferrite beads provided an surplus of energy"  ;)

and that's how the manufacturers are getting 95%+ efficiency with recent SMPS designs - adding a lots of energy generating ferrite beads... while telling us it's because of EMI.... EMI my ass ! it's quantum vacuum's brother from another mother !  :-DD  :-DD

Myriad of things, but it mostly boils down to: phase angle isn't really a useful quantity anymore. It's from the olden days when AC current drawn was still pretty much perfectly sinusoidal.

As current drawn gets more distorted (i.e. SMPS without PFC), phase angle measurements using certain principles get more and more wrong. A proper true RMS AC power meter will simultaneously sample voltage and current going into a mains-connected device many times per second, about 4kS/s minimum, and multiply-and-sum it to get the actual power drawn. Cheapo power meters only measure a couple times per second and assume that 'in between' it's probably a smooth curve, or even worse: it's just sinusoidal. If it isn't, the meter just displays a wrong value because it is based on wrong assumptions.

Even worse, there often is literally no phase angle in SMPSes and other sub-unity power factor devices. The current waveform is perfectly in phase with the voltage, but it's just very heavily distorted. The cosine phi should be 1, but the power factor should be lower.

This is one of the big reasons why cosine phi and phase angle shouldn't really be used anymore in literature. It is just very confusing and doesn't represent what is going on at all anymore. Power factor is a more generalized term which also accounts for distortion instead of just phase angle.

Hi All,

This is my first post here, after signing up.

I do believe in good science and proper evaluation and I thank Dave for the time he spent on the debunking video. So in light of this... I will ask have any of you heard of John Bedini and his SG Enegizer? Dave mentioned the Joule Thief so I suspect he may of heard of John's SG circuit.

A quick google and the first page I started to read about John and his Simple School Girl thing had this gem in it:

"more aether radiant energy is being captured, but independently of the strands, sucked up by each transistor mounting plate from the heat sink. Needless to say by using transistor pads and grease you are restricting the aether radiant accumulating process potential"

Hmmm... well...

Ok... That is not John Bedini's site that is the site of Erwin-Badertscher.

Anyway we see in the schematic that a pulsed inductor is rotating a magnetic rotor and the flyback energy is charging a second battery of equal capacity. In this configuration the machine will give you some mechanical energy and recover a certain percentage of your input energy via flyback. At the very least one can expect to recover 30% on a poorly tuned machine and recover very close to 100% of what you put in from the run battery, depending upon how the circuit is configured.

Dave, this was not only a most humorous video, but educational as well.  I'm just getting back into the Electronics thing after many decades of inattention, and found that I was able to pretty much predict what you were going to say next, so I must be learning. :-)   

I started reading the original thread in the blog, and my eye muscles got tired of the rolling motion, so quit wasting my time reading about "free energy."   When I saw that you'd created the video (at about midnight my time), despite being tired, I stayed up to watch it... and found myself both laughing and being absorbed with the lesson.  Thank you!

A resistor in series with the capacitor makes the on-time more predictable.
The on-time is controlled by the capacitor and its series resistor. 
Just trying to make this circuit more predictable ;)
Do you mean something like this-I'm not analog fan, but rather like to live in digital world, so not sure if this change is what you talking about?

It could be fun to use only two transistors and by adding some toroid core make simply low power SMPS.
I've found BC557 & BC337 Spice models, so I can try simulate this thing in Spice and try to adjust R11, R12  or remove them if current between PNP and NPN transistors will be limited nice by PNP gain, but it could be nice to find a way to have similar ON/OFF times...
but probably this R13 resistor will create voltage divider with oryginal R10 100k and this oscilator will not work..
Anyway it looked like the only possible way to make C10 capacitor similar RC constants during charge and discharge, or I missed something?  ::)

So with the Bedini we have two different things going on with this School Girl (SG) Energizer /oscillator, that were not present in the circuit presented by the person in Dave's video. First the inductor imparts a magnetic field that is used to rotate the rotor and second the diode directs the flyback into the second battery as it is across the coil. It is plain for all to see that these two things set the SG apart from what we see on the video and on this thread.

Yep, oryginal circuit from this thread wasn't perfect - my modified circuit now is simulated in Spice and... If I will make it usable and stable at vacum, I will be able light on not a few wats LEDs but.. a few kW (kiloWats) light bulbs ...with AC mosfets switch which needs so small charge on input, but can output hundreds, if not thausands more power  :-DD

I can tell just from glancing at the schematic, and all the lossy components, that it will never come even remotely close to 100% You are dreaming.

If Bedini actually received a patent for his "Randiant" energy, then I'm very disappointed.

John Bedini and his machine, was broken into three seperate patents...

If you look back I said...
...and recover very close to 100% of what you put in from the run battery, depending upon how the circuit is configured.


I said "depending up how the circuit is configured."  You must configure the SG system in a manner that allows maximum energy recovery. So how do you do this? You simply connect a motor or oscillating circuit across a higher potential battery, with a lower potential connected in series with the load. All current you use from the higher potential battery is drawn through the lower potential battery and it receives a charge that is dependant upon the load and the differential voltage between the two batteries.

Do not knock it until you try it... It works and is not a joke.

See images below.

In the four position paint diagram...The lower potential(1.5volt single cell) dead battery will receive all current from the low resistance load that comes from the 3 volt side because the polarity and current flow are in the proper direction to charge the single 1.5 volt cell. Since the positive and negatives are connected together we have a voltage differential or difference of 1.5 volts... So 1.5 volts is powering the circuit, at whatever amp draw the load is drawing.

Try a electric motor and then an electric light bulb and see how the low side battery charges. And compare the results. Anyone can do this and see how we have been mislead into believing that we must tie the load directly to ground only and not directed into a lower potential battery before tying to ground.

It conserves energy. You can power a circuit or load and have the capability to recycle or store all the energy you expend in powering your load.

Take three identical batteries and arrange them with a light bulb or electric motor as a load, as the image above describes and you will see what I mean.

No you should not take that to mean I have not taken the measurement. 

I have done multiple tests with different loads. In one such test I took a 12 volt fan motor and placed it between the three fully charged lead acid 12 volt batteries as described in the drawing, it ran at 800mA. It started to quickly over charge the small side 12 volt battery while running on the differential between the two sets of batteries. It should be noted that the more you load the shaft of the DC motor the higher the charge rate of the small side battery would increase.

The machine as drawn with four batteries will recover the amps you use in the circuit. It proves that an electric motor does not convert electricity into mechanical energy as the electricity can be recovered in the small side differential battery before going to ground of the 24 volt primary. Plus you also get all the shaft energy and the recovery from the coil collapse.

Anyone can do the simple test of putting two 12 volt batteries in series for 24 volts and then connecting the negative of the 24 volt bank to another single 12 volt battery negative and putting a DC motor in between the two positives and running the motor to see if the 12 volt single battery will charge or not.

Of course it will charge, if it has current flowing through it. But that doesn't mean that it can get back the energy expended in the load.

Look, it's really simple. You analyze such a system by drawing a control envelope around it and looking at flows of energy that cross the system boundary. If all the batteries are inside the envelope and the the load does something useful (i.e. it transmits power outside the envelope), then the total energy that starts out inside the system decreases. The only way to reverse that situation is to transmit power back inside the envelope from outside. None of the diagrams you showed indicate a power flow back into the system. Therefore the system will lose energy until it can no longer do any useful work.

You don't seem to understand. What you expend in the load you lose. It's gone. If you start out with $100 in your wallet and you spend $40, your wallet is $40 lighter. You can't magically attach rubber bands to the $40 and get it back after you have spent it. Once spent, it is gone. To replace it you have to get more money from somewhere else, for example by working and getting paid.

You are charging a battery and powering something else at the same time. Nothing unusual or overunity about that. Keep doing it enough times and you'll find that all the batteries eventually discharge to nothing.

Anyone can do the simple test of putting two 12 volt batteries in series for 24 volts and then connecting the negative of the 24 volt bank to another single 12 volt battery negative and putting a DC motor in between the two positives and running the motor to see if the 12 volt single battery will charge or not.

-Dave Wing
LOL, that is the same as when you charge iphone batter from the power bank  :-DD. In this particular case fan works like current limiting ballast. When you load the shaft, current through fan increases, therefore battery charges faster. This is fucking stupid, you could put the resistor or light bulb instead of the fan and will get exactly the same result. There is no free energy, you just transfer energy from one battery to another.

I never said there is any free energy involved... Just recycling what a load uses so it can be used more than once in a electrical system.  It does not have to be lost directly to ground as we have been taught.

That is ridiculous. Seriously.

The motor spends energy if it rotates (it also spends a little amount of energy has heat). That is gone.

But you know what? If you really can recycle the energy you spent in the motor, then why not replace the battery to be charged just with another motor (instead of storing the recycle energy in the battery use it for the 2nd motor).
You can then also recycle the energy spent in that 2nd motor (you obviously know already how to do that with the 1st motor), and you can then add a 3rd motor (and recycle the energy you spent in that motor). Then add a 4th motor... And so on, and so forth...

Eventually, you have enough motors with enough combined torque to drive a bike. Add some more motors... finally (after you added enough motors which all use the recycled spent energy of the motors before them) you can drive a highspeed train with a little 12V battery. Do you really seem to think that this is possible, or am i missing something?

LOL second time. Nothing is recycled. Actually energy loses are higher than if you just ran the fan from a single 12V battery. Charging is not 100% efficient, therefore when you charge one battery from another even more energy is lost. These are school level physics.

If we have a fully charged battery... The lead ions are free to move and are not trapped in the plates of a discharged battery...so the efficiency of the battery stays at a very high level and we can now run another identical motor directly across the small side 12 volt battery and that particular battery will remain in a fully charged state with no further current draw from the 24 volt battery section.

Do the test below and see what happens... Then put another identical load across the fully charged 12 volt battery and see how it affects the 24 volt section voltage and current draw of the first load. Let me know what you find out.

There are no lead 'ions' at all in a lead-acid battery. There are electrons and hydrogen ions (protons). The hydrogen ions can indeed move freely...

You don't seem to understand. What you expend in the load you lose. It's gone. If you start out with $100 in your wallet and you spend $40, your wallet is $40 lighter. You can't magically attach rubber bands to the $40 and get it back after you have spent it. Once spent, it is gone. To replace it you have to get more money from somewhere else, for example by working and getting paid.

Believe me at one time I thought the same way...

Look guys just try it... Surely you can get three identical batteries and some type of load together.

That's not how it works.
You've claimed something extraordinary against the basic law of conservation of energy, so you are the one that gets to prove it to us.

Look, it's really simple. You analyze such a system by drawing a control envelope around it and looking at flows of energy that cross the system boundary. If all the batteries are inside the envelope and the the load does something useful (i.e. it transmits power outside the envelope), then the total energy that starts out inside the system decreases. The only way to reverse that situation is to transmit power back inside the envelope from outside. None of the diagrams you showed indicate a power flow back into the system. Therefore the system will lose energy until it can no longer do any useful work.

Exactly.
And it's not just the load that transfers energy outside the system, it is the internal resistance losses in the chemistry and battery construction that also dissipate energy as heat.

Generally... What you expend in the load you get back. That is what I am saying... Do the test.

Basic battery charging theory shatters your entire illusion.
This is why coulomb charge counting circuits require calibration, because of the losses.
If you measure 1 coulomb of charge going into a battery, you won't have precisely 1 coulomb of charge in there to draw back out because of the internal losses.
If you think otherwise then you have not measured your system properly.

What's ground got to do with anything?
This is all about losses in the load and battery internals as heat. This heat energy escapes your closed system, never to be returned. That very real energy comes from the chemical energy in your batteries.
You can capture some of that otheriwse wasted energy to put back into the system and charge the batteries, like regenerative braking does in electric cars, but you can't get it all back.

 @DaveJones
Trying to debunk the ENTIRE free energy domain by ranting theatrically over a video of an idiot on YouTube, makes you an idiot too. And an asshole. Because you are mocking the memory of hundreds of researchers that were marginalized, discredited, threatened, blackmailed or suppressed by the Vested Interests.

You showed everybody how limited is your thought process and what jerk you can be.
No serious researcher in the free energy field will claim he gets more energy out than total energy in. There is not such nonsense as overunity. What you're missing is the ENVIRONMENT, that you presume to be empty. But if you would pull your head out of your quantum ass, you would discover the real life physics, not the one truncated and isolated from the environment that millions of children learned in school like robots.

You should apologize to all subscribers by saying this:
"I, David Jones, I am too stupid, stubborn and arrogant  to admit there are things I don't understand. In my retarded philosophy, if I don't understand them, that means they don't exist. So I apologize because I tried to manipulate you and used a stupid video of an amateur to cheapen and degrade the free energy research domain. I didn't make the slightest effort to separate the amateurish work of a loser from respectable scientists or anonymous researchers that had their lives ruined or terminated because they tried to give humanity the energy freedom, progress, and civilization. I humbly admit I did wrong."

If you do not feel the need to apologize or if you try to excuse yourself coming with pathetic semantic twisting games, you will lose any kind of respect from anyone having an open mind towards scientific progress.

But matter can be transformed into energy and is in a battery even. Wherever there is a chemical reaction some matter is lost as heat energy, weigh the coal and air going into a power station and the ashes and fumes coming out and the difference in weight is the energy produced. So energy has mass and mass has or is energy. Put that together with the 3 batteries and fan and even if it was 100% efficient you will eventually run out of reaction mass ie. the lead and acid.

Not accurately, no, but it's not going to be much higher than the 1.5V input voltage.
So yeah, it's probably going to be better than the 50% ballpark, but not by a huge amount.
Wasn't my intention to measure the efficiency at all.

A lot of people do say that, and yes I agree, it's probably not good to do a fundamental Friday video and use a 1GHz scope to probe an RC time constant.
So I am mindful of that, but ultimately I'm going to use whatever I feel like using at the time.

Interesting video, I didn't expect that a battery would be only discharged by a few percents with a short for a minute.

I've found that a very common misconception, that's why I wanted to make a point of that.
It's actually not intuitively obvious just how much chemical energy is contained in a typical AA battery, it's a lot!
A long time back I was going to do a video on showing how much energy is in a AAA battery, might still have to do that one.

It depends what's a lot for you (it can be for example a 250W entry-level electric bike...).
But for LEDs yes, they can be extremely frugal, especially the red ones. I have a RED INOVA Microlight I bought in 2004 and I put it in the Chrismas tree way before Christmas - it was still on the original battery (in fact I didn't even had the faintest idea how to replace the battery, almost broke the damn thing). It kept going on for something like 2 weeks! The red LEDs of that type have some lower voltage and you can direct drive it with just one CR2032.

Then around New Year's Eve I put a new battery (not one of the "good" ones, I have some other thread where I'm complaining about the quality of current CR2032s, I've got a bunch of them, different types to test). Is stil lit (not really bright but you can see it). 3-4 weeks after.

That was the best and most satisfying debunking video I've ever seen.  Right up there with Pen & Teller's Bullshit (a debunking show in the states). 

It is worth understanding these people though.  I see them not as irritations, but warnings.  And its something that happens so often, to so many people.  They get the spark of curiosity, and start experimenting or investigating.  At some point, experimentally do something they find amazing - but there is nothing amazing.  They simply possess a critically incomplete understanding of the physics behind an otherwise understood phenomena.  They are unaware of this incompleteness, and mistake cracks in their broken half-knowledge for something amazing, something world-changing, something everyone else missed.  But there is nothing there, there is nothing great, there is just unseen ignorance combined with optimism taken to a fault. 

They latch onto that idea, that feeling of something stupendous, and almost like the first hit from a crack pipe, they keep chasing after it with amazing focus and determination, and INVARIABLY, they end their own education.  They've decided they know enough, because they know all they need to know to chase after the next hit from the crack pipe of imagined innovation.  They know enough to have found this thing that everyone else missed - and believe detractors are blind to what they can see so clearly.  And the idea is always one of such hope, promise, and unknown ignorance that anyone else who knows too little to know better will simply see a hero.  Someone who is doing great work, will change everything.  So they act as such, and suddenly, you're hitting that crack pipe while a bunch of other crack heads cheer you on, tell you how heroic you are for smoking crack, all the vitamins crack has in it, all sorts of good stuff. 

And that, the (obliviously unwarranted) appreciation and praise and support and respect these people garner from other similarly or more uneducated people, often peers, friends, family as well as others online, is very powerful, I would imagine.  I don't know how easily I could give up something like that, honestly.  It's very easy to understand how, with friends and ignorance on their side, to see everyone debunking their 'discovery' or otherwise dropping phat knowledge bombs all up in their business as trying to destroy all that, as the enemy.

Thus, knowledge becomes the enemy, and learning comes to an end. 

I am glad for videos like this one and people like you, Mr. Jones, because maybe stuff like this will keep someone who might have enclosed their mind in that cage wrought of equal parts ignorance, good intentions, and emotional reinforcement, will keep learning how to think, and thus keep learning.  I would not wish anyone to lose out on the greater wonders of reality.  The people like ManOfStone will never feel the beauty and wonders and mystery of the real universe - in all its staggering enormity - wash over them.  They'll just chase after what began as an innocent flaw in their understanding. 

And for that reason, they have my sincerest and deepest pity.

E=mc^2.  If something is hotter, it's also heavier.  This is why objects with rest mass (or put another way, their intrinsic energy content) cannot reach the speed of light from *any* subjective inertial reference frame, because pumping more and more kinetic energy into the relativistic object makes other observers see it as having more kinetic energy, which makes it more massive, which makes it require even more kinetic energy to increase its momentum vector, which if added ups its mass even more...and it gets closer and closer but never quite reaches the speed of light.  But anything that releases heat is also losing mass, while whatever the heat flowed into has gained it.  The kinetic energy released in chemical reactions (or rather, change in enthalpy) is heat, which is more or less internal kinetic energy of a bulk mass of particles.  Whether its from the molecular forces accelerating stuff or a piece of an atomic nucleus pulled far enough that the residual strong force from the quart triplets is overcome by the electrostatic repulsion from other protons as in fission, or if protons are forced close enough that the residual strong force overcomes electrostatic repulsion to slam together, making hydrogen into helium like fusion or our sun, it's still kinetic energy, still heat, and mass is lost by that system, but moves into others. 

There is no 'conversion' of matter into energy.  Matter is energy, or rather, mass is simply a property of energy.  In fact, its generally inconvenient to represent objects using mass in astro or quantum physics, we use energy and momentum vector because it is much more intuitive and simplifies the math.  Since mass is relative and dependent on the frame of reference something is being observed from, we use the http://en.wikipedia.org/wiki/Energy%E2%80%93momentum_relation , which amounts to the same information.  That's derived from the earlier link, so you should also read that one, as it continues why what you said is incorrect.  Also, from that, we can proceed to the Stress-energy tensor, from which the gravitational field in Einstein's field equations are directly built upon.  It drives home the point that matter, radiation, and fields of force (like electromagnetism) can all be broken into energy and momentum vectors: http://en.wikipedia.org/wiki/Stress%E2%80%93energy_tensor

So no, mass is not 'only' converted in atomic nuclear reactions.  Mass is a property or energy, and any movement of energy is also movement of mass. And as mentioned earlier, mass cannot be converted into itself (energy).  When you understand those articles and why what you said was nonsense, you'll be that much wiser.  Or you can simply ignore it - but then how are you any different from the free energy people ignoring engineers and science and willfully refusing to learn?  ...You wouldn't be.  So read up :)

I never said there is any free energy involved... Just recycling what a load uses so it can be used more than once in a electrical system.  It does not have to be lost directly to ground as we have been taught.

What's ground got to do with anything?
This is all about losses in the load and battery internals as heat. This heat energy escapes your closed system, never to be returned. That very real energy comes from the chemical energy in your batteries.
You can capture some of that otheriwse wasted energy to put back into the system and charge the batteries, like regenerative braking does in electric cars, but you can't get it all back.

That is why I said generally... As I will concede that I do not have the proper scientific equipment to measure with such accuracy. But never the less I can and will show a large percentage of recovered energy that is normally lost in the system can be recaptured for later use.

Questions: How much energy does a 12 volt 1157 or 1156 bulb expend in heat and or photon losses in watts? Is it fair to assume that we can not show any input energy recovery from a simple light bulb?

Much respect also for the, in my view, respectful way you give feedback and comment to those who are completely ignorant or full of …
(solar roadways, grafeen capacitors, free energy etc). That must mean something, as i'm from the Netherlands and apparently regarded as being 'direct'  :)

Not respectful enough for many it seems, I get many complaints about my delivery and direct tactless nature.
My care factor is zero, my style is my style ;D


And i for one, applaud your style!!

I treat these "free energy" idiots with the same disdain as those idiotic "moon landings never happened" morons.  Simply punch them hard, and fast, directly in the face.  After they have got back up off the floor and said "what did you do that for?" simply reply "What?"  i didn't do anything. When they say "yes you did, you punched me in the face" you say "no i didn't, never  happened mate".................................   ;-)

You would rightly think i was a moron............



All you have "discovered" is that current flows between objects of differing potential, and that work can be done when a potential difference and current flow exists across an object.

I'm pretty sure you are not going to get a Nobel prize for that, being just, as it where, approximately 280 years behind Benjamin Franklin...............

I'm very happy to see you using affordable gear in your videos (and i bet i'm not alone!)  big thumbs up for that  :-+ :-+ :-+ (actually it would be boring and annoying to see you probing a $2 circuit with a 1GHz scope :D)

A lot of people do say that, and yes I agree, it's probably not good to do a fundamental Friday video and use a 1GHz scope to probe an RC time constant.
So I am mindful of that, but ultimately I'm going to use whatever I feel like using at the time.

I am all for the use and promotion of affordable gear. I was watching TheSignalPath Blog Youtube channel yesterday and saw a review of a Keysight MSO-S-Series scope fully optioned up, in what lifetime or alternate universe can any of us afford a 68,000 dollar oscilloscope! The probes alone probably cost as much as my scope!!! It was a good and interesting review but in reality not practical for most of us.

Q1: It's unlikely anyone here can answer that off the top of their head - the usual approximations and/or datasheet values for those devices are close enough for most uses.

However, it is something that can be calculated relatively easily with a fair degree of accuracy at home or in a high-school-level physics lab. Want more accuracy? Go talk to a university or suitably-equipped metrology lab...

Q2: I dunno, you tell us? You're the one claiming you see energy 'recovery' with 3 batteries & a motor. In your 'experiment', where do you think the energy is being 'recovered' - the batteries, the motor, or both? Note: it's not necessarily the same place where you think you're measuring the 'recovered' energy...

(p.s. Its been fun watching this, but I'm off to bed...)

Basic law, energy can be neither created or destroyed only change state
But matter can be transformed into energy and is in a battery even. Wherever there is a chemical reaction some matter is lost as heat energy, weigh the coal and air going into a power station and the ashes and fumes coming out and the difference in weight is the energy produced. So energy has mass and mass has or is energy. Put that together with the 3 batteries and fan and even if it was 100% efficient you will eventually run out of reaction mass ie. the lead and acid.

 :wtf: Man you need to read some Wikipedia before posting. Chemical reactions do not change matter into energy. They release potential energy stored in the chemical bonds. Mass to energy conversions only happen in nuclear reactions. Manofstone's stupidity must be contagious.
And that energy is mass,only a very small mass but mass none the less.
 The products weigh less. Energy has this much mass: E=mc2 <==> m = E/c2. Does not matter what kind of bonds it is stored in.
This is not relevant for most purposes but supposing you have your perpetual motion battery set up going on forever the result will be the disappearance of the lead and acid. All hypothetical I know but not rubbish.

Dave; not to debunk debunking, but you talked about efficiency, and compared current to current to make the claim 50%.  However the voltage on the output (clamped at LED Von, 1.8V?) is somewhat higher than the input (1.5), so total power efficiency is probably a little higher than what you suggested.  Still the guys claims are just silly.

Yep, inductors do that. The output voltage rises to whatever the circuit needs when the magnetic field collapses.

I once built a joule thief running off a single AA battery and used it to light up a string of LEDs (ie. in series). You can easily get the inductor output voltage over 20 Volts to light up the LEDs.

I just can't stop laughing at you. What electron recovery you are talking about??? That Wikipedia citation states that only 5% of energy get converted to the light in visible (to human eye) part of spectrum. All other energy will be radiated as Infrared light and transferred through thermal conduction / convection. There is no energy loss, it does not disappear, the thing is we get only 5% energy converted to the form we desire, while 95% gets converted to what we do not need. BTW what electrons are you going to recover while electrons never leave this circuit? They just flow through it.

@DaveWing  Free energy is everywhere most in heat - probably bad inductors were used in this @Dave experiment - toroid cores should be different - filled with quantum vacum which lowers down air temperature around those special cores and absorbs thermal energy, but this happends only at given frequencies, so @Dave have no chance to notice this-he didn't make temperature measurements around cores  and cores itself :o
You are right and I'm close to prove this in my enhanced version of this circuit shown in debunk video ;)

You are in a good shape to The Ig Nobel Prizes if you change those claims into more improbable research http://www.improbable.com/ig/     >:D

Just look at the Siemens Velaro train family, among them the fastest (and the whitest, if i may say) trains currently in service around the world. They just have two batteries with 280Ah. How do you think they can drive the trains at such speeds with those two meager batteries? Yes, they recycle the electron currents that went through a traction motor to use them again in the other traction motors.

Also note that the trains specifically have two batteries. The second battery is of utmost importance for the electron current recycling.

Go, and look into such a high-speed train for yourself. There are only these two batteries. If you don't believe, please show me the other big-ass batteries that would drive that train then...

And before you go and point out that there is a wire hanging above the train, i urge you to look again. Yes, there is a wire. Many clueless people have argued that this is somehow related to electron currents. But this is not the case - there is no battery connected to that wire. Nowhere. The wire is just a safety line to prevent the train toppling over when it derails in an accident -- similar to the safety line mountaineers use to secure them from falling off the cliff. You can even see the hooks on the roof of the trains that attach to the safety line...

Now, am i a smart person, or what?  >:D >:D

Hi Dave.

I believe in hard science and crisp logic, but "I want to believe" in overunity.
Maybe it is possible, just beyond our current knowledge.

Anyway you hit the point with this video.
Explaining why something doesn't work, gives knowledge about how stuff really work.



Once I posted this question : "Why doesn't this work" (on another forum) about this picture,
and expected a scientific answer, but instead my thread got deleted...

Is this worthy of a ten minute video, please?

Thanks.Cheers.

While i applaud your curiosity, you approach your problem from the wrong angle. If you start from your assumption that it works then you need to be able to explain why do you assume this. Difficult, ehh? Better is another approach. First you should specify the strength of the magnetic fields between magnetic poles in your drawing there. Then consider the spatial relationship between the magnetic poles, and therefor the amount and direction of forces exerted on each magnetic pole. Based on these forces and interactions you can then explain how this should work or not work. Happy thinking...

By the way, if you use inferior construction materials together with strong magnets, something like in the picture below will happen :)

Simple.  They convince themselves that education from established science is mere "indoctrination."   The "laws" of science aren't theories that have stood many tests and experiments and have been proven to be good models of the universe, they are propoganda perpetuated by the educational establishment.  Once one believes that, then one can believe that with a few magnets, or some water, maybe ferrites or a "quantum vacuum" one can generate free energy.

My therory is that the frontiers of science are so far advanced, that there is a frustratingly large amount of prerequisite material that must be learned before one can begin breaking new ground.    Oscillator circuits have been studied for years, and we pretty much know all about them, but someone in their basement hooking up transistors doesn't want to do the boring research to explain that circuit - it must be free energy and these programmed people who have been brainwashed by "the establishment" can't see that.

Most "basement innovation" is engineering - applying new technology in innovative ways that no one else has thought about.   A maker with an Aurdino may revolutionize horse feeding, but he or she can't make the hay from nothing.

I mean, what could possibly supply the power for the traction motors, maybe the perfectly standard pantographs easily visible in this photograph?



Yes, they do have batteries. They need power to run over any interruption in power from the overhead 25kV lines and to power the train systems when the pantographs are down.

For those not too deluded for rational thought there is a lot if interesting info on these trains here - not one mention of any snake oil solutions allowing the train to run on a torch battery but plenty of standard high efficiency stuff, regenerative breaking etc.

I just don't know much about magnetics and would like a quick and dirty video.

You actually don't need to know anything about magnetics to analyze that system.

Simply consider any position of the rotor and ask if there is any difference in the shape of the system with different rotor positions? It should be evident that any rotor position is equivalent to any other rotor position (for instance if the diagram is printed on paper, you can simply rotate the diagram to bring the rotor back to the original position). It follows that if all rotor positions are the same as all other rotor positions, there is no reason for the rotor to move from one position to another. If the rotor is stationary, it will always remain stable at whatever position it is in.

What I want to know is how people can believe that the people who built (eg.) the Large Hardon Collider know less about physics than uneducated people mucking about with coils of wire and magnets in their garages.

Simple.  They convince themselves that education from established science is mere "indoctrination."   The "laws" of science aren't theories that have stood many tests and experiments and have been proven to be good models of the universe, they are propoganda perpetuated by the educational establishment.  Once one believes that, then one can believe that with a few magnets, or some water, maybe ferrites or a "quantum vacuum" one can generate free energy.

My therory is that the frontiers of science are so far advanced, that there is a frustratingly large amount of prerequisite material that must be learned before one can begin breaking new ground.    Oscillator circuits have been studied for years, and we pretty much know all about them, but someone in their basement hooking up transistors doesn't want to do the boring research to explain that circuit - it must be free energy and these programmed people who have been brainwashed by "the establishment" can't see that.

Most "basement innovation" is engineering - applying new technology in innovative ways that no one else has thought about.   A maker with an Aurdino may revolutionize horse feeding, but he or she can't make the hay from nothing.

When I went to school many professors confessed they never seen a DIP package or used a soldering iron.
The knowledge is backed up by lots of experiments and practical applications, but educators maybe never did one of them.
They just crammed it to pass an exam. (sort of indoctrination)

I am not claiming to have made free energy machine nor to know more then scientists.
But there are limits to current knowledge and amount of knowledge of one person.

The point is that many improvements in physics came from debugging misconceptions.

The problem is there is no misconception here.  Science pushes boundries... this isn't something that has room to be pushed.  We have "all factors compensated for" in this case.  Down to impurities slowing down the speed of light in different traces, and the inductance of every single wire.  It can all be simulated.  And I do mean ~all~ factors can be simulated. 

However, your dreams of reactionless drives... it seems those do not necessarily violate physics ;-)  But that's a story for another thread.

Ok here is my video of what I am talking about. The light bulb charges the small side battery and we are free to take the equal amount of energy out as another load.

So next will be how we can incorporate this system into the Bedini SG Energizer so we can get shaft energy and flyback energy on top of what you see in this video. So what do we have that was not in Dave's video that he used to start this thread? It should be clear to all what we have here.

"I want to believe" in overunity.

why?

Because without it and Q-thrusters and EM drives we are stuck to this solar system.

Why, 100 k years to get to the other side of the galaxy isn't that long, haven't you always wanted to watch all videos on youtube during your flight from A to B?
Or read all books ever written?

Some small nuclear reactor, or normal hot fusion reactor is enough to power some live support machines for 100k years,
you just need to work on human longevity and you will not be stuck to this solar system no Mather how slow you travel.

And in contrary to breaking the energy conservation laws there are no known fundamental limitations to human longevity, achieving (a)biological immortality is just a Mather of some more technological progress and once its done subjecting your natural biological body to enough treatments and augmentations.

Edit: and of cause before all living long enough to be still alive when this technology's will become available.

Counter example: I seen lot's of DIP packages, and used a soldering iron many times. I do not know jack about analog electronics and the physics behind them. I might even made a few experiments without really understanding what was going on. But according to your reasoning i would be magically able to understand the physics just because (A) i know where to touch the soldering iron without burning my hand, (B) i can poke with the soldering iron at said DIP package and (C) can execute an experiment without thinking just by merely following instructions. No!

Just because you had a bad teacher does not mean science is hocus pocus. It just means that you had a bad teacher, nothing more.

I would add that if you know Lawrence Krauss than you know that total energy of the universe is zero.
Yet universe is something rather than nothing.
Also Alan Guth has a theory how to make matter vanish. (It is on Youtube but I can't provide a link.)

So there is a hint of plausibility to free energy but only on grandest scales in science.

Correct. Homopolar motors have spacial symmetry, but they are not symmetric in time. If you move the clock forwards or backwards the state of the system changes. This is what makes the difference. With permanent magnets in the system you pictured the state of the system is the same now, this afternoon and tomorrow.

This relaxation oscillator circuit is actually pretty interesting, and I was thinking of applying it. A friend of mine is a flight sim enthusiast, and he built his own TrackIR rig out of a ballcap and some LEDs, to avoid having to pay for the expensive, "official" headset. Problem is it runs off expensive 9V batteries and chews through them like no one's business. I was thinking that this oscillator circuit could help him power it off of cheaper AA batteries, and also get more Whr out of each battery.

What do you think of my revised circuit?



I added R2, as I noticed in Spice that Q2's base was pulling ~120mA with no resistor, which seemed inefficient. Adding the resistor drops it to ~20mA. I also added a trim pot to allow the LED brightness to be tuned with different batteries.

Think this would work well, or would I be better off with the "classic" Joule Thief circuit?

You will be miles ahead with the Bedini circuit ... I posted the drawings on page 10, very last post of the page. It can be run as a solid state unit that will charge a battery across the coil.

Dave; not to debunk debunking, but you talked about efficiency, and compared current to current to make the claim 50%.  However the voltage on the output (clamped at LED Von, 1.8V?) is somewhat higher than the input (1.5), so total power efficiency is probably a little higher than what you suggested.

No, at lower average currents the voltage drop is lower than that, I said that earlier in the video.
I did not accurately measure efficiency, that was not my intention, it was a throwaway comment I should have prefaced better.

Admin,

Well if it is done all the time why are we not using it in our electric motors, household appliances, cars and houses?

Back to the circuit I posted earlier, John Bedini's circuit, it is an oscillator that has mechanical output and it can capture the flyback energy as well... Plus when you factor in splitting the positive as my video shows... The current that powers the light bulb is passed into an inverted series battery, you don't even comment on it. I have shown you three solid ways, over and above what you went over in the video that started this thread, that give you a very high return, if you put them all together you will have a motor that will run under a high amperage load for peanuts.  Now what electric pulse motor does all this?

Have you seen the video I posted? Here is the link in case you have not. http://youtu.be/X4dJdEDwjgU

As can be seen in the video the light bulb is emitting photons and heat, apparently that is where the energy is going, it is being converted into those two things, at least that is what classical electrical engineering tells us. So if this is the case what is charging the small side battery? Answer that question please?

Difference with the real engineering is that he is not collecting anything just wasting even more.
DaveWing I am supposing a challenge for you. Compare fan run time if 1. just using two fully charged 12V batteries in parallel and 2. what you will get when using your circuit with two fully charged and one discharged battery (which is used for energy recovery as you say). When 2 Charged batteries gets empty, run the fan from that single "energy recovering battery" and then calculate total fan run time.
P.S. recommend to not discharge batteries until zero volts to not damage them. But control the moment when voltage on single battery decreases to 10V and consider that as discharged state. For experiment to be really true, I reccomend to consider "Discharged state" voltage (when you stop counting fan run time) on the energy recovering battery to be exactly the same as voltage on it before experiment was started. Therefore you can count all true run time on so called "recovered energy".

Purpose of this experiment is that at the beginning you have equal amount of energy = 2 fully charged batteries. Then you can compare how effective is your circuit compared with fan just running without so called "wasted energy collection".

This is incorrect.  Mass *is* energy.  They are just two different ways of measuring the same thing.  Please follow your own advice and regarding wikipedia, only I will provide the specific article that confirms what I am saying.  There is no article to confirm what you've said, so your omission of a link is understandable: http://en.wikipedia.org/wiki/Mass%E2%80%93energy_equivalence

The products weigh less. Energy has this much mass: E=mc2 <==> m = E/c2. Does not matter what kind of bonds it is stored in.

OK lets see you guys power up your toaster with some mass.

It would seem that you haven't had the luxury of formal education.
In Chemistry, one of the elementary concepts that you learn is that mass is conserved.
In Physics,  you learn and do equations about how mass is converted into energy. This is the basis for nuclear reactions. The enriched uranium fuel is being consumed and released as energy.

Stringing jargon together may work on some people, but to those who understand and have studied the subject, you sound like an idiot. Believe me, special relativity does not come into play inside a battery. It's as much gibberish as these quantum vacuum inventions.

You sound so invested in your ignorance that I've lost the motivation to discuss it with you.

Can you please recommend some links or videos about this time asymmetry of homopolar motor?
I haven't yet had a go at vector calculus, curl, del operators and what not...
So something at a hobbyist level, please?

It's really not that complicated. It you look at one of the classic homopolar motor experiments on the internet there is a 1.5 V battery in the middle of it. When the motor is running this battery is discharging, which means the state of charge of the battery is changing over time. If you leave the motor running overnight and come back tomorrow, you will find the battery in a different state than it was today. This is all that I mean.

The asymmetry comes from the difference in what happens when time runs in the forward direction to what would happen (hypothetically) if time could go backwards.

Another way of looking at this is that there is an energy gradient available and an opportunity for the system to go downhill following this gradient.

True. But in the context being discussed, the effects of special relativity are so tiny that it's essentially in the noise.

Well if it is done all the time why are we not using it in our electric motors, household appliances, cars and houses?

Electricity is so cheap that it isn't worth it.

By the way, that image with the three batteries is hilarious... Are the arrows showing how gravity movies the electrons or something?

Also, any news on the video quality issues?

Hi,
Perhaps you can answer this question below.
As can be seen in the video the light bulb is emitting photons and heat, apparently that is where the energy is going, it is being converted into those two things, at least that is what classical electrical engineering tells us. So if this is the case what is charging the small side battery?

Here is the video in question.... http://youtu.be/X4dJdEDwjgU

Yes. And you can also calculate the vacuum energy. That doesn't mean that manofstone's oscillator taps into it, any more than a battery taps into rest mass energy. You people have wild imaginations.

Maybe try some search on the internet about battery charge and it's mass relation? Or better about chemical reaction and mass relation.

The two batteries on the left. Your video clearly shows the voltage across the series battery; starts at 25.77, drops to 25.01 when loaded.

The potential (chemical) energy in your battery. Once all that chemical energy in your battery gets converted into light/heat, then the battery is dead, no more potential energy.

-Dave Wing

Hilarity ensues!

Do you know that electric power is the product of voltage times current?

Electric power is energy spent per time. That is:  1W = 1 J/s

The battery supplies that energy which is converted by the light bulb into heat and light (in an amount respective to the lights power rating and the capability of the battery to provide the respective amount of energy).

I hope you realized that there is a voltage drop across the light (i have not watched your video). I really hope...

The amount of voltage drop is proportional to the power (and thus energy) spent by the light bulb as heat and light. Or saying in different words: The energy consumed by the light bulb (converted into heat+light) causes the voltage to drop. The current is the same before and after the light bulb; it does not change at all, why should it?

No thanks. That won't be necessary. I understand the relation very well, and it's irrelevance to the subject. I eagerly await batteries which extract electricity from mass.

Ok according to Kirchhoff's current law what is going on in the circuit I posted below. I am asking an honest question here.
If you were to put the light bulb across the negatives of 24 volt and a 12 volt battery system? What results can we expect to find?

You really should be able to tell by looking at the picture what will happen, you shouldn't need anyone to explain it to you, even if you don't understand all the details. You can also do the experiment yourself to find out, maybe by using small rechargeable batteries instead of big 12 V ones.

Assuming batteries 1 and 2 start out fully charged, and battery 3 starts out empty, and assuming the blue circle is a bulb, then:

Initially the bulb will light brightly. Over time the bulb will grow dimmer and dimmer until the combined voltage of batteries 1 and 2 equals the voltage of battery 3. At that time the bulb will go out and the system will stop changing.

When the system has stopped changing, battery 3 will contain some of the energy that was previously contained in batteries 1 and 2. The rest of the energy that was contained in batteries 1 and 2 will be lost to the environment, either as light or heat. Some of the heat energy will be lost by the bulb, and some of the heat energy will be lost from the batteries due to their internal resistance and other inefficiencies.

If you do a total accounting of the energy present in the system at the start and the energy present in the system at the end, the energy at the end will be less than the energy at the start by the amount of energy lost to the environment.

Can you be sure that that's not just some sort of numerical instability? The time domain is necessarily quantized is this sort of simulation; so obviously every pulse's sampling phase will be slightly different and any resulting inaccuracies in the simulation will manifest themselves in different ways each time. Try configuring your simulation to use smaller time steps, and see if the pulses become more similar to each other.

First time poster here.  I've found this to be an interesting place!  I haven't been around long enough to know if DaveWing is serious, but if so, here is my attempt at simplifying it.  As an aside, I have spent most of my career doing analog/power/battery/charger designs in a position where I am required to assist/teach design engineers with a wide range of experience from rookies to the most Sr. Engineers.  I've learned patience :)

In your example, let's make the following assumptions (you can change any of them and rework the math, it doesn't change the results, this just makes the numbers work out simply in your head).
1.  Let's ignore parasitics (battery ESRs, charging efficiency, etc.)
2.  Your "source" batteries on the left are 1.5V each.
3.  Your "charging" battery is at 1.5V

This means 1.5V across the motor (3V -1.5V).  Let's say that with the mechanical load and 1.5V across the motor, the current is 1A.  This means 1A through everything in the loop.

So, you are sourcing 3V*1A=3W.  The motor is using 1.5V@1A=1.5W and the "charging" battery is also using/accepting 1.5V@1A=1.5W.  You are sourcing 3W, and using 3W.  What is the mystery?

If you do a total accounting of the energy present in the system at the start and the energy present in the system at the end, the energy at the end will be less than the energy at the start by the amount of energy lost to the environment.

And to do that you could discharge the batteries completely after the test and log the results to find out how much energy was left in them. And along with knowing how much energy was in the original batteries to begin with, and also the log of the load power over time, you'll get the result as IanB states.
For a ballpark measurement you could likely ignore the battery and charging losses.
DaveWing should do this before talking any more about this subject, it's just getting painful.

DaveWing, I think you need to go back to school. You have really missed the plot. I noticed that your 12V battery left any longer without a load would have exploded especially after seeing the voltage rise above 15V. Maybe it would have been a good idea to leave it running and let the out gassing pour and maybe would have seen some sense.

The only thing that allow people to believe there is something else mysterious is that there is no real interrelating theory between the large and the small. What you are trying to do here is say you have proved it. Don't bring this kind of shit to an engineering forum instead it needs to go back to science forums, tell them you have cracked the theory of the small and watch them laugh you out of existence.

"I want to believe" in overunity.

why?

Because without it and Q-thrusters and EM drives we are stuck to this solar system.

Why, 100 k years to get to the other side of the galaxy isn't that long, haven't you always wanted to watch all videos on youtube during your flight from A to B?
Or read all books ever written?

Some small nuclear reactor, or normal hot fusion reactor is enough to power some live support machines for 100k years,
you just need to work on human longevity and you will not be stuck to this solar system no Mather how slow you travel.

And in contrary to breaking the energy conservation laws there are no known fundamental limitations to human longevity, achieving (a)biological immortality is just a Mather of some more technological progress and once its done subjecting your natural biological body to enough treatments and augmentations.

Edit: and of cause before all living long enough to be still alive when this technology's will become available.

Trax


Oh, but those Lifetime @ Temperature ratings of Electrolytic Capacitors just kill it.  :(

Bullshit, you of cause use some machine with self repair capabilities, for example a system that contains recycling and manufacturing plants and a few hundred drones to operate and repair/replace broken parts.
And of cause the drones would also be subject to replacement/repair.


Also coming back to your initial assertion:
Quote
Because without it and Q-thrusters and EM drives we are stuck to this solar system.

Why do you think you need overunity to leave the solar system?
Why not just use some good old space warping drive that can operate on some amount of energy you can generate by normal means like hot fusion or from a tank of anti mater?

At what point would you be Dependant on an infinite energy source?

@Trax

You have proposed many amazing technologies but I proposed just one.
Not that I don't like a good sci-fi setup.
100K years is just too much, any technology you put in your space ship would be obsolete in 20 years.
Look at Rosetta spacecraft, it has a camera of 4 megapixels because 10 years ago they couldn't do better.
And also there are 100 billion other galaxies.

What I never understand about free energy/overunity people is why they work so hard to convince everyone else on the basis of silly Youtube videos and the like.  If they've got something real, then just build a house-scale system, disconnect from the grid, call the news reporters a year later, and collect your Nobel Prize and billions in royalties.

But instead all the passion goes into convincing everyone that there's some kind of conspiracy to keep us all oppressed or something.  They just sit around saying, "Yes sir, everything would be awesome except for the bloody oil companies suppressing the truth!"

I think many of these people really do believe the nonsense they push, at least on the surface.  But the reason why no one ever builds anything practical (i.e. solves a real-world problem over significant periods of time) is because deep down they suspect that maybe it doesn't really work.  They intuitively understand that the shortest path to cashing out with some money is always convincing some foolish investor on the strength of a charismatic pitch rather than the strength of, say, not having paid any electric or fuel bills lately.

Just build the damn thing and have done with it already.

And Dave, your rants are always entertaining, but this video also taught me a lot about circuit analysis and inductors so thumbs up both ways!

Much respect also for the, in my view, respectful way you give feedback and comment to those who are completely ignorant or full of …
(solar roadways, grafeen capacitors, free energy etc). That must mean something, as i'm from the Netherlands and apparently regarded as being 'direct'  :)

Not respectful enough for many it seems, I get many complaints about my delivery and direct tactless nature.
My care factor is zero, my style is my style ;D
I like it like that. It's way more fun. Those who are "offended" are those who feel attacked by the content of the video, because you show their ignorance in full light. And it's worthwhile because it's an informative video.

Keep it like this, no bullshit is the right way.

And yes, I subscribed just to say that. :)

Dave Wing, I'm trying to understand your circuit.
- 3 12 volt batteries, 1 amp-hour capacity.
- A fan that draws 1 amp when 12 volts is applied to it.
- Wire them up according to your diagram.
- For simplicity, let us assume perfect batteries. If you allow a current of 1 amp to flow, they will take 1 hour to discharge. If you apply a charging current of 1 amp, they will take 1 hour to charge. (I wish...)

Dave,  can you enlighten me by answering these 5 questions?

1: How long will the fan run before the 2 batteries go flat?

- When the 2 batteries run flat, attach the fan across the 3rd battery.

2: How long will it run for?
3: What is the total time of the two runs?

4: The second run is powered by the energy recovered during the first run - energy that would have otherwise been lost. It's the same energy that was used by the fan in the first run. Is that correct?

- Now recharge the 2 batteries. Connect them in parallel, not series. Connect the fan across them.

5: How long will the fan run for?

Regards...

No thanks. That won't be necessary. I understand the relation very well, and it's irrelevance to the subject. I eagerly await batteries which extract electricity from mass.
It's an atomic pile, also called an atomic reactor. It doesn't extract electricity, but energy from the fission of atoms, which is used to heat water vapor, which is then converted to electrity via turbines. Apart from chemical reactions, there is no physical effect that allows direct conversion from mass to electric energy AFAIK.

Explain something to me please. If you power a light bulb directly across one 12 volt battery and it draws one amp at 12 volts. Where is the current going? What gets converted into light and heat?

-Dave Wing
Aaargh! Kirchhoff's current law is not a power or energy law! How can a bulb glow, if the current into the wire before it is 1 amp, and the current out of the wire is 1 amp?

Your question is fundamentally wrong. Nothing besides the chemical energy in the batteries are converted to light and heat, and the current return path is retardedly hindered by a back-to-front battery needing another battery to compensate!

Naturally the low side back-to-front battery will charge. If the lamp produce 12 watt, the battery will be charged with about the same, at the expense of 24 watt from the two batteries powering the circuit.

There is nothing to be "reused". Your circuit doesn't reuse any energy at all, it only uses more energy than needed. Yes, you CAN reuse energy in some circumstances, like regenerative braking but your circuit has non of it.

You will get more light and heat if you put all those batteries in parallel, at least the two batteries powering the lamp and strip away your silly back-to-front battery.

There is nothing to be explained really. You lighting up a bulb and charing one battery with two batteries. The light and heat have nothing to do with the charging, it is not the "same energy" and nothing is reused. On the contrary, your losses are greater comparing with no charging of any battery.

Batteries 1+2 will drain, the lamp will light, battery 3 will charge.

Energy will be lost to the environment as heat and light (mainly heat I suspect - the batteries will warm up).

Maybe I'm a bit slow, but ... is something unexpected/miraculous supposed to happen?

As far as i can tell Dave Wings misunderstanding seems to be thinking that "current" is power.   He is saying that if 1 amp goes in, and 1 amp comes out, then no "energy" has been "lost".

Of course, this is incorrect, as previously mentioned.  So, Lets assume Dave W is a moron, and try and explain it to him in simpler terms.  For this, i am going to replace "current" with "weight" and "voltage" with "gravity" (height)


So Dave, concentrate, here comes the (not much) science!


Here is an escalator:



Normally used to move people up and down in buildings, they usually take electrical power and use that to move the steps fixed to a continuous conveyor.  Hopefully you can see / understand roughly how they mechanically function?


Now, lets not power the escalator, but use the motor as a generator, and simply attach a lightbulb to the wires of the motor.


Statically, nothing will happen, because the mass of the conveyor is balanced (with say 30 evenly weighted steps hanging on each side of the pulley that the motor is attached too).


But now, lets put a 50kg weight on a step on the top side.  Now the system is unbalanced, and the converyor will start to move, turn the generator and light the lamp.  Until of course, that weight gets to the bottom of the escalator and slides off. Att which point the steps will stop turning and the lamp will go out.


With me so far?



Now, instead of putting just one weight on the steps, lets keep putting them on.  Everytime a "new" step comes up and around, lets put a 50kg weight on it.  Now the system keeps turning, we keep adding weights, and they keep falling off the bottom one at a time.  The lamp is lit all the time, as the steps keep turning.  But we are not changing the weights in any way,just like your electrical circuit doesn't change the "Current" in any way, and yet power IS being extracted from the system.


In the case of our weight powered escalator, the power we can generate depends on the mass of the weights we add, and how far they can fall under the force of gravity.  Add more weights or add them higher up and more work is done.  In effect, the weights are the "Current" and the height they come down from the "Voltage difference".  In all cases, if you stop adding weights, say because you are tired, the system will stop and no power will be generated.  And in all cases, the weights (the current) are not changed by the process, just moved to a different (lower) location, and some other entity will need to add external "power" to keep the process running (in this case, you, carrying the weights back up to the top one at a time)


Hepefully, this mechanical analogy might help you understand that Power or Work Done, is the product of Current and Voltage (P = V x I), and that considering just current or just voltage is not sufficient to be able to establish the work done in circuit.

I have documented evidence that free energy does exist.

12 years ago I moved into a new house, got all the utility connected and did not receive an electricity account until they decided to install a smart meter 2 years ago.We had free energy for 10 years, so there you go.

They could only bill us for the prior 9 months based on the forward 3 month average, so we read books by candle light or a couple of months until a bill turned up for sweet FA.

Hi Guys,

Such was my interest on this topic that I registered and this is my first post !

So, why don't we organise a 'competition' to see how much 'light' someone can get out an AA battery ?

We would just need to specify a battery and a means of measuring the total light out ?

Any means of doing so but probably exclude 'nuclear' (e = mc2 options  !

Anyone up for it

You could do this every month, just don't pay the bill on odd months but pay it together with the new bill on the even months. In your universe you will have free energy every odd month  :D

This would need to be an even playing field and the first constraints that come to mind are how do we all simultaneously synchronise our measurement equipment, and how will every participant maintain an equal temperature globally.

I normally dont throw spanners, ever.

You need to define the term "how much light". Are we talking maximum brightness? Average lumens over X amount of time? Longest battery life? And then decide how that will be measured. Dictate a common battery and LED. Probably all devices would need to be tested by one person with the equipment who can do an unbiased test.

I like the idea though. Could make a contest out of it. And the free energy chumps could join in and see if their quantum vacuum fairy dust can beat out some good-old-fashioned math and engineering.

There is probably no single brand/model of AA cell that is available everywhere.
And even if there were, there is no way of knowing whether the total capacity (WH) is the same in all places.
Or even how fresh the cells are when/where you buy them.

Might be easier to simply specify a given power (voltage, current) and take the battery chemistry/freshness out of the equation.

And there is the matter of specifying many terms and conditions: monochromatic vs. "white"
And, given how LEDs produce "white", what is the definition of "white" anyway?

And then, as you mention, there is the matter of calibrating light measurement.
Do you want to go into the business of selling calibrated sensors?
And then how do you select a sensor that would be impartial to all wavelengths?

Not impossible, but there are several interesting challenges to resolve.

We already know the answer to that question.

We also know the "chumps" won't change their magical thinking one iota, no matter what the result is. They know that real-life experiments are irrelevant because the big breakthrough in magic energy is "just around the corner". All it needs is a bit more fiddling around with magnets to achieve it...

PS: Unfortunately LED efficiency has passed sodium-vapor lamps. Lighting a sodium-vapor lamp with an AA battery would be an interesting challenge.

Yep. There's no way a real-life battery could be used, you'd have to specify a voltage, eg. 1.2V and let people go with that.

According to Wikipedia the theoretical limit for white LEDs is about 260-300 lm/W:

http://en.wikipedia.org/wiki/Luminous_efficacy#Examples_2

Cree claim to already be there:

http://www.cree.com/News-and-Events/Cree-News/Press-Releases/2014/March/300LPW-LED-barrier


So... the competition would therefore be who can build the most efficient voltage booster to light up a Cree LED using a 1.2V input. I don't think the engineering for that will surprise many people.

You couldn't specify *just* a voltage, or you could hook up a 30A supply and light up a whole bank of LEDs.

I honestly think the best way would be to specify a specific LED and a specific battery, and have the contestants send their circuits in to the contest runner for the testing. They can just pick whatever batteries are available for them, it shouldn't matter as long as they're reasonable quality and all the same.

I think we could also make it more interesting by putting additional restrictions, for instance maximum of 8 components, etc. Then measure both light intensity and battery life.

I fully understand stock shrinkage, it is a part of what I do.

From what I heard, this non billing of hundreds of customers was an oversight by a number of electricity providers, and even early in the peace we notified them on many occasions that we hadn't received an account, nothing ever got attended to, so we gave up trying.

We were expecting a bill for around eight grand and would have happily paid it, but it turned out that legally they couldnot request any more than 9 months worth prior. I still feel really guilty to this day.    :bullshit: :-DD

All good now though.    :-+

Ok according to Kirchhoff's current law what is going on in the circuit I posted below. I am asking an honest question here.
If you were to put the light bulb across the negatives of 24 volt and a 12 volt battery system? What results can we expect to find?

You really should be able to tell by looking at the picture what will happen, you shouldn't need anyone to explain it to you, even if you don't understand all the details. You can also do the experiment yourself to find out, maybe by using small rechargeable batteries instead of big 12 V ones.

Assuming batteries 1 and 2 start out fully charged, and battery 3 starts out empty, and assuming the blue circle is a bulb, then:

Initially the bulb will light brightly. Over time the bulb will grow dimmer and dimmer until the combined voltage of batteries 1 and 2 equals the voltage of battery 3. At that time the bulb will go out and the system will stop changing.

When the system has stopped changing, battery 3 will contain some of the energy that was previously contained in batteries 1 and 2. The rest of the energy that was contained in batteries 1 and 2 will be lost to the environment, either as light or heat. Some of the heat energy will be lost by the bulb, and some of the heat energy will be lost from the batteries due to their internal resistance and other inefficiencies.

If you do a total accounting of the energy present in the system at the start and the energy present in the system at the end, the energy at the end will be less than the energy at the start by the amount of energy lost to the environment.

So how much battery capacity (a rough guess will suffice) will battery 3 receive from batteries 1&2, provided they all have the same amp hour capacities when fully charged?

So if battery 3 does receive a percentage, in the form of actual battery capacity from batteries 1&2 is that not better than the conventional model that directly loses all and recaptures none of the battery capacity it uses?

What would happen if you connect a capacitor in place of the battery number 3? Could you not power the bulb for a certain time period or until the capacitor potential equalizes with the two batteries 1&2. When the capacitor equalizes disconnect the cap from the circuit and power the light again until the cap is discharged. Repeat process over and over. Yes there will be losses but not much, you input one part energy and used very close to two parts energy.

I will post a video showing the losses in the system, just like Dave has requested, shortly.

So if battery 3 does receive a percentage, in the form of actual battery capacity from batteries 1&2 is that not better than the conventional model that directly loses all and recaptures none of the battery capacity it uses?

Well....yes, but you had to use TWO batteries (1+2) to do that.

If you take out battery 3 then you can also take out battery 2 and still light the lamp. Overall this will be more efficient because the initial charging of battery 2 is lossy and so is the charging of battery 3 when the circuit is running.

What would happen if you connect a capacitor in place of the battery number 3? Could you not power the bulb for a certain time period or until the capacitor potential equalizes with the two batteries 1&2. When the capacitor equalizes disconnect the cap from the circuit and power the light again until the cap is discharged. Repeat process over and over. Yes there will be losses but not much, you input one part energy and used very close to two parts energy.

The average light output will be halved because the voltage across it is constantly ramping up/down between 0 and 24V.

ie. There's no real-world gain.

First, I'm going to use a resistor as a crude approximation for a light bulb.  If I understand your hypothesis correctly, the exact load doesn't matter anyway.  So we have this circuit:


When power is applied, the capacitor is fully discharged so R1 gets the full voltage applied to it, and the maximum current begins to flow.  But this current begins charging the capacitor, and the capacitor voltage begins to rise.  This rising voltage means there's less voltage across the resistor (the sum of the voltages must be the battery voltage), so the current drops.  Eventually the capacitor is charged up. 


We can already see something you I'm not sure you were accounting for: the "bulb" isn't going to be at full brightness very much (the yellow line.)  But now let's do the analysis that IanB talked about: energy in and energy out.  The question here is how much energy did that take from the battery, and how much energy was used by the bulb?  Since current was changing constantly over time, the math is a little non-trivial.  Multiplying the current curve by the voltage gives you power, and then integrate that to get energy.  This is NOT just a current analysis!

We'll treat battery voltage as constant for now and ignore the other "minimal losses" you talked about.  There is a well-known formula for capacitor charging, so I can do this quite precisely.  With the values I used in the above schematic, the battery supplies 1.44mJ in the time it took to charge the capacitor.  How about output? How much energy ends up in the capacitor? This works out to 0.72mJ.  Not surprisingly, doing the calculus to figure out how much energy was dissipated by the resistor yields 0.72mJ.  So it all adds up: half the energy from the battery went to the "light bulb" and half to the capacitor.  Now you propose dumping the capacitor energy into the light bulb, which is fine.  The energy still came from the battery initially.  Energy in = Energy out.

That's not to say the circuit doesn't have interesting properties.  Pulsing the load like this is a form of switching dc to dc converter, and there are situations where they are quite useful.

Another great video Dave! I thoroughly enjoyed the explanations and bringing things back to science! Too often the uninformed public without any science and particularly physics or engineering education are misled by the media, by people who wish to profit, and sometimes unintentional "believers" who don't understand what is going on and resort to mystical explanations rather than picking up a good book on fundamental theories.

One thing I did NOT do is click on the original free energy video that you linked because the last thing I wanted to do is to increase their YouTube video hits, which I assume are monetized. By watching the original video they would just gain more Adsense profits.

Anyways, excellent video as always!

Well, let's try it with a 1000 ohm resistor.  The energy that ends up in the capacitor will still be 0.72mJ because that's how much energy the 10u capacitor can store at 12V.  And the energy drawn from the battery... calculus... 1.44mJ.  Same as with the 10 ohm resistor!  The difference is that it takes much longer.

I will post a video showing the losses in the system, just like Dave has requested, shortly.

-Dave Wing
But no!!!
To be ignorant is one thing, we are all here to learn something. But you maintain your delusion even when we point it out to you that you will not gain anything, and that's worrisome. You have mixed up the notions of current, voltage, power and energy and this is nothing that's is open for discussion. You are simply wrong.

If you by "part of energy" mean the energy consumed by the bulb when charging the capacitor, you have used two such "parts". One for the bulb, one for the charging. That the bulb is in series with the caps doesn't come in to the equation. So, assuming no losses whatsoever, charing a cap and use the cap to drive a bulb is just a very stupid and convoluted way of drive the bulb.

You cannot save an attojoule with your scheme. You clearly need to go back to basics and learn Ohms law, the power law, the relationship between power and energy and realize that a conductor transmitting electrical energy is not the same thing as using this energy. And, you cannot use Krichhoff's current law locally to measure energy of a whole system globally.

You sir are dead wrong. Totally wrong. There is no discussion at all. Your scheme isn't even reminiscent of real power saving ideas like reusing braking energy. There is nothing, absolutely nothing in your idea that will save, conserve or make clever use of energy. The only thing your scheme does, is maximizing losses. Period.

If you do a total accounting of the energy present in the system at the start and the energy present in the system at the end, the energy at the end will be less than the energy at the start by the amount of energy lost to the environment.

And to do that you could discharge the batteries completely after the test and log the results to find out how much energy was left in them. And along with knowing how much energy was in the original batteries to begin with, and also the log of the load power over time, you'll get the result as IanB states.
For a ballpark measurement you could likely ignore the battery and charging losses.
DaveWing should do this before talking any more about this subject, it's just getting painful.

@Trax

You have proposed many amazing technologies but I proposed just one.
Not that I don't like a good sci-fi setup.
100K years is just too much, any technology you put in your space ship would be obsolete in 20 years.
Look at Rosetta spacecraft, it has a camera of 4 megapixels because 10 years ago they couldn't do better.
And also there are 100 billion other galaxies.


Well what I am proposing is technology that is realizable in accord with the laws of physics, what you are proposing is to the best of the words knowledge impossible.

It is irrelevant if the technology will be out dated in 100k years if its done right at the day of manufacturing it will be still working in 100k years and thats all that matters.

Also you ignored the fact that for leaving out solar system with FTL speeds we don't need infinite power but we need some loop whole drive that would bypass the limitations set forth by the theory of relativity, ...

Over unity is for all intents and purposes a nice to have but by no means necessary for us to leave the solar system.

Your argumentation is flawed in any conceivable way sorry...

The other HUGE problem with all these "free energy" ideas is that nobody actually understands what "free energy" really means. For example, how many times does someone claim they are gaining "energy" from *nothing* when it is actually just converting something else that is not obviously apparent.

For example, even in this example of the LEDs... what "energy" is actually being created? A bunch of dim red photos popping out of 23 LEDs as a result of work done by a AA battery with a comparatively large amount of chemical potential energy still stored in it. I still see a chemical reaction losing potential while photons are gained. Overall net loss anyways due to the inefficiency of the system, heat loss, etc.

Even in cases where energy appears to be freed from nothing, if you look closer at the system you may find perhaps it is a nuclear reaction. No matter where you look, the conservation laws of physics are still there. No exception. Even if you could blame it on some "quantum" gobbledegook winkidinky, it is still coming from there... it is not "FREE" because conservation must always be observed. Nothing in life is FREE.

Hi Dave,

Your video had me laughing so much I had to come to the forum and say hi!

Man, his original posts are real troll nuggets. Throwing around unrelated terminology & using fancy terms to disguise his lack of circuit knowledge. The funny thing is he could have used one toroid with 3 windings and it would work better with less space than a stack of 5 toroids. Although I heard quantum vacuum energy sticks better to black tape... :palm:

If you have a metric ton of cash laying around, the most hardcore way to debunk most of these circuits would probably be to measure the outbound energy flux (mostly heat & light, also electrical parasitics?) and integrate it over the battery lifespan. That amount of shed energy would be equal to the chemical energy capacity of the AA-cell and everything's dandy according to the law of energy conservation.

Of course, the electrical way to debunk is a lot more interesting. Many thanks for the big refresher on how these boost converters work!

Greetings,
GlowGale :)

I see one immediate (and major) flaw: Capacitor charging is not linear. Adding together the three voltages at the end does not tell you that the total energy in the system is the same.

Energy in a capacitor is proportional to the square of the voltage.

24.9 * 24.9 = 620
(7.92 * 7.92) * 3 = 188

So the total energy in the system went down by about 70% when you lit up the bulb (from 620 to 188)

Before we can explain more complicated circuits to you, you are going to have to take some time to understand the basics.  Consider this circuit:



There will be 1.2A flowing in this circuit.  The same current flows through both resistors.  It does not change since these parts are in series.  If the two resistors were wired in parallel, then the current would be split between them.  But they are not wired in parallel; they are wired in series.

While the current remains the same, the voltage drop over each in-series component will be different.  And the sum of the voltage drops across the in-series components will be equal to the total voltage supplied by the battery.

In this example, since the resistors have exactly the same value, exactly half of the voltage will drop across R1 and the other half of the voltage will drop across R2.  The battery is supplying 24V, so the voltage drop across each of the resistors is 12V.

We can now calculate the power used by each resistor.   Power equals current times voltage.  12V * 1.2A = 14.4 W

In other words 14.4 Watts are used by R1, and another 14.4 Watts are used by R2.  The total power used in the circuit is 28.8 Watts.

Notice that R2 does not reuse the power used by R1.  Some power is spent in each, and all of the power in total comes from the battery.

If you now look at your simpler circuit with three batteries and a light bulb, you will see that it really isn't all that different from my example.  You have two 12V batteries in series, whereas I made up a single 24V battery in my example.

Instead of two resistors in series like my example, you have a light bulb and a third battery wired in backwards.

A light bulb and a resistor are nearly identical from a circuit analysis perspective.  The light bulb turn power into light and heat, the resistor turns all of the power only into heat.  But they both use up power, and it isn't really important where that power goes, it is gone.

Granted a battery is not quite as simple as a resistor, but the division of power between the light bulb and the battery works in much the same way as the division of power between the two resistors in my example.

The important thing to remember is that with components linked in series, the voltage drop will be split between them.  The split will not always be even, because the ratio of the voltage split is determined by the ratio of the resistances of the components.  But it _will_ be split.  Therefore the power expended in the circuit will also be split amongst the components.

No magic.  No reuse or recycling of power.

What you didn't show, but rather conveniently assumed, is what happens when you actually do put those caps in series and re-inject the circuit. Sure, you get 24V, but putting those three caps in series might give you 24V but the capacitance is now only 3,333uF.

You need two equations, one for the energy held in a capacitor given its capacitance and the voltage across its terminals, and one for calculating the capacitance of several caps in series.

Your setup loses 2/3rds of its energy mostly in the light bulb.

Yes, I was thinking about that as well. It is like a pendulum swinging... and each time it passes through the lowest point it drives a "wheel" that spins for a bit. Eventually the pendulum runs out of energy. As the pendulum is raised, it has "potential" (like the capacitor plates charged to a certain voltage) and as it is allowed to swing it builds up kinetic energy (like the current travelling through the light bulb it does work), but then it does not raise back up to the same potential energy. In this case the calculations show 2/3rds loss each pass or swing.... Energy being lost as light and heat by the bulb. Like a super-bouncing ball or pendulum.

Hi All,

This is my first post here, after signing up.

I do believe in good science and proper evaluation and I thank Dave for the time he spent on the debunking video. So in light of this... I will ask have any of you heard of John Bedini and his SG Enegizer? Dave mentioned the Joule Thief so I suspect he may of heard of John's SG circuit.

Why do all of these silly "free energy motors" use batteries ? Why not replace the batteries with a suitable capacitor with an initial charge. If the contraption is unity or over unity as claimed then the charge on the capacitor will never decrease or increase if it is over unity. I'm almost certain that the capacitor will eventually lose all of its charge ;)?

Resistive load selection is important, the less the internal resistance the better and more efficient the energy transfer. The diagram as seen below and the video http://youtu.be/X4dJdEDwjgU I posted was not meant to be run as a continuous closed loop system... It was meant to be a pulsed based open loop system. I only ran it closed loop to demonstrate that recovery is very possible, also I wanted to raise the question why we are not doing it with our large powered systems that we use everyday in our daily lives.
You do not see it used simply because it does not work that way: if you use two batteries and a shunt element to limit current into a third battery, half the power gets used by the shunt and the other half goes into the third battery, minus the batteries' internal losses. After the first iteration, you now have two dead batteries and one (mostly) charged one assuming it started discharged - if the third battery started charged, then you wasted half of your first two batteries as heat into the third one since batteries dissipate excess charge as heat - at least they they do not vent gas or explode.

Now you can take your third battery and run your 12V load for about the same duration as you did with the first two. By the time the third battery is depleted, you will have run your load about twice as long as a single battery could have, which you could have achieved by simply connecting batteries #1 and #2 in parallel, and omitting battery #3 altogether. You save the expense, weight and space of a whole battery.

Battery #3 does not contribute anything useful to your circuit; all it does is compensate for ridiculously poor initial design in an expensive (if you are going to run a 12V load, run it off 12V), potentially dangerous (overcharge hazards) and impractical (need to swap batteries around) way. Put two batteries in parallel, ditch the third and call it a day: simpler, safer, no battery handling required, no additional efficiency loss from having to charge the unnecessary third battery.

Resistive load selection is important, the less the internal resistance the better and more efficient the energy transfer.

Are you saying you want the load to have a low internal resistance? In your diagram you show the blue circle as a "Low Resistance Load".

Now, this is where you run into trouble. Let's take this to the limit and assume we can make a "load" with zero resistance. Perfect, right? Except, no, not at all. If a load has no resistance it will consume no power and do no work. It will be completely useless. In order for a load to be useful it must have resistance. There is actually a "best" resistance to choose, not too small and not too large. At either extreme, low resistance or high resistance, the power will approach zero and nothing useful will be gained. Somewhere in the middle, with the right resistance, power transfer is maximized.

Do you ever go to the gym and work out? If you want a good workout you have to set the resistance on the machines, right? If you set the resistance to zero, how much of a workout do you think you will get? Setting the resistance to zero will do you no good. It will be like doing weight training with a feather.

Regarding the video please excuse my rough delivery. Thanks for watching... http://youtu.be/K6CpDaksxh0

Not rough at all, it's very good in fact, streets ahead of the majority of youtube content like this.

I admire you people for trying to educate this DaveWing guy, however he is so brainwashed by his own lack of knowledge that you yourselves are wasting precious energy. Another guy out of the same mould as ManOfStone.
They honestly believe they have discovered the EE version of the Ark of the Covenant, or the Elixir of Life.
They have seen the magician perform his illusion and honestly believe it to be true…

I cannot be bothered wasting my time with these twits.

Video was a good laugh though, thanks Dave.

I am off to read some more EE informative threads…

So what's the problem then. Why don't these dudes take it to its logical conclusion and power their house with it ? What is stopping them ? Why make a big who-ha about powering up a few leds or a motor that couldn't pull the skin off a custard ?

cheers

Thats exactly what I was thinking. Why are they fooling around with stilly YouTube videos when they could be out making money powering their whole neighborhood at practically 100% profit.
