Free Energy Scams and Fakes
<< < (4/20) > >>
lewis:
My workshop aircon unit uses 1.6kW of electricity to produce 5.5kW of heat. Stick a load of efficient thermocouples in series between the hot and cold bits of the heat pump and BAM! Free electricity. Easy.

Kickstarter anyone?
ConKbot:
Youtube is full of people that are all about free energy etc...   I saw a video about a ball bearing motor (you have a shaft on two bearings, apply DC or AC across the bearings, and the localized heating where the bearing contacts the race causes expansion and the motor to spin, but its not self starting) A simple physics demonstration, that Ive seen in the past. But there are people insisting that:
A) its an induction motor (never mind the fact current is running though the rotor, and there is no windings...)
B) its a homopolar motor (better guess than induction but still wayyy too much friction for that)
c) people who say its a scam (fair enough, enough crap on youtube to be doubtful first)
And last, but certainly not least:
D) The BEDINI MOTOR OVERUNITY, YOU CAN USE THIS WITH PULSER CIRKIT TO GET 4-10V OF POWER AND TO CHARGE AND SUSTAIN ITS OWN POWER SUPPLY.


Gah, I see all sorts of stuff that makes me ask 'why!' People winding all sorts of elaborate motors and windings, and magnets, and so much effort put into it just to fart around, where if they put that much effort into learning the underlying physics, then  they wouldnt even need to mess with this and could do something productive with their time.   I know 4hv has to actively chase off the overunity crowd. Though I'm sure they find the simple winding of a tesla coil secondary passe and boring by now :p

Its fun to use careful wording to get the ire of physics teachers/etc in school.  "5.5 KW out, 1.6 KW in, thats 344 percent efficiency!"   >:D

You can tell that in their heads they are thinking  'YOU CANT BE OVER 100% EFFICIENT EVER, GAH! '

So they use the term "Coefficient of performance" for heat pumps, so above heatpump would have a CoP of 3.44, and it doesnt tweak the over 100% efficiency nerve  ;D
Terabyte2007:
It all comes down to "The Law of Conservation of Energy". You can't argue with physics!

The real problem I see with the free energy , is that it takes away from any alternative energy sources getting a foothold and helping with are moving to better other sources , especially decentralize or distributive energy .
I think there was a point in recent history ,  that education made people resistant to BS , but the powers that be / or want to be , have use the DUMBING DOWN in the schools , to make it easier to bull crap the masses .
What is the worst thing about the believers = people who have limited knowledge fall into being sheep !
Just my understanding of why we are not reaching almost any potential , most the corruption of greed .
The classic definition of propaganda = if you can not hide the truth / you mix it with so many lies that no one will figure it out .

Well it seems you've fallen for a bullshit of your own choosing as well - the conspiracy theory bullshit.

There is no concerted effort to make mankind stupid. Mankind is stupid enough by itself. And if a tendency can be explained away by plain old human idiocy and good-intentioned bad decisions, then according to Occam's razor, one should not hypothesize the existence of some secret, undetectable pink invisible spaghetti monster that plots and conspires to make people stupid and immoral through media and education.

EDIT: Actually, I think the anti-establishment conspiracy theory thought that you too are advocating, is the main reason people are more prone to believing scams these days. The reason selling over-unity scam stuff was harder 50 years ago (was it?) is not that people were smarter, but that people trusted science and scientists.
Nowadays, if a physics professor stands up and speaks out against over-unity scams, many will simply dismiss him as "a pawn of the powers that be / big oil / the reptilian space jews" or whatever.
Conversely, an underdog "inventor" con artist, who is borderline schizophrenic, blames all sorts of outside interference, and says something totally contrary to any accepted tenet of science, sounds "authentic" to many, because he's an underdog, and because he goes against the authorities... which makes him a "good guy".
