The good thing is you get to choose friends, so pick them wisely as one day, they could be family  :-DD

Very true. Then you can escape from your family with them!

Ok...this shit annoyed my by repeatedly contaminating my legitimate search results. This whole site seems extremely shady and back-ally, plenty of stuff to rant against for years. :rant: The comments are equally rediculous and stupid. :palm:

You will find a lot of snake oil where I live.
The shops sell it.
The streets are flowing with the stuff.
It is highly spoken of.
They are also taken in tablet form.

Oh that's special: "Since the basic idea is that an otherwise normal electrolytic capacitor can be brought into a state whereby it converts ZPE into usable electric power, our first step would be to study this effect in detail. I will discuss this in another post later."

So basically the crazies have latched on to dielectric absorption now as well  :palm: ... have they worked out you still have to put the energy in there first and it doesn't just magically appear out of thin air?

Oh no because that's the conspiracy!

i registered just so that i could share this here.

https://www.kickstarter.com/projects/niccharger/nic-charger-the-first-truly-and-totally-wireless-c/description

i dont remember how i found out about this, but its obviously fake. however i dont have the knowledge yet to do the calculations as to WHY its fake.
after watching plenty of the EEVBlog videos debunking obvious crap, and Thunderfoot's videos too, i do have the knowledge to say that this thing is bupkis.

the fact that the devices start "charging" but use a dodgy animated charging screen that no device ive ever seen actually has. the only clip that shows a real charging indication, has a guy's finger holding up the charging coil, very possibly hiding a cable/wire.

a few quotes from their page:

*under a big "How It Works" banner
"The NIC system consists of two parts, the NIC charging cube which is connected to a power outlet and the NIC charging pad which can be permanently connected to your portable device."
obviously not actually saying HOW it works.


"NIC Charger is part of NIC Enterprise Ltd, Founder in 2016 by a group of 3 electrical and electronic engineers."
something tells me this is bullcrap too

"Proven Technology

Nikola Tesla created the first wireless energy transmission in the 1900s. It is now available for most of your portable devices."

and there's a reason we dont use this. 

there is one comment from a sensible person, who thankfully made a pledge just to post their contradiction to their product.
unfortunately, since they cancelled the pledge (which is totally fair IMO) kickstarted hides their comment, making it
FAR less visible.

just thought id share this here, in the hopes that someone can bust this turd for the world to see

Thanks for posting that. That is utter trash indeed.

Numbers for you assuming I haven't futzed the calculation (I am using windows calculator so this is likely):

0. Assume 100% efficiency at all transducers and conversions and adherence to physics.
1. Transmitting antenna has a no gain (it's omnidirectional clearly)
2. The receiving antenna is a generous .0025 square meters in size and I assuming it is poorly projected onto a 3d plane here to be lazy.
3. The receiving power required is 5W (5V 1A) for charging which is stupidly not generous.
4. Receiving end you would need a power density of 2kw/square meter.
5. 5m away from the source, that translates to a power of 628KW.

I don't see anyone catching fire during charging there and that wire is a bit thin for a 628KW feed.

But they started their video with "Have you ever wished...." and even mentioned Tesla further down, so it MUST be genuine!!

No wireless charger that I've owned has been that good, and the device had to placed directly on top of the transmitter, a trickle charge at best and the device gets stupidly hot in the bargain. Threw them in the bin and used a standard charger and lead, not a problem.

The current wireless chargers are inductive. You've got a transformer secondary in your phone and the primary is in the table. Those work pretty well TBH but the usable range is just over an inch. They claim 5m with this one  :-DD

(and no I don't use one - efficiency is only 75% on a good day!)

On another forum I was attended to a so called "ground box".
It is a wooden box with some copper strips in it and filled with different stones. It should help to ground your audio set, esp. when you live in a skyscraper or high appartment far removed from the earth ground level  :)
They sell for thousands of $'s and to me it smells like snake oil.
Whats your opinion  :bullshit: or  :-/O  ?

That's a con for sure. It's the same as the old portable earth:



A lot of people think that all you need for something to work is to believe it does which is wrong.

I wonder what the magic crystals are claimed to do.

They claim they work as an advanced filter for the earth ground wire absorbing all noises from and into the audioset. You know audiophiles think in noise and earth is the holy grail of getting rid of these noises  :)
They claim the result is so significant that an ab test is not needed.

To ground the neutral, does one need a bag of Swiss compost?

Cerebus doesn't know whether to join in with the bad jokes or whether to get the custard pie cannon.
Anybody got a syringe I can use to squeeze the magic smoke back into this?

That's a classic example of what the [Obscure joke:] tag was invented for. Everybody but thee, me, and bd139 are now scratching their heads. Anyway, not much chance of an F35 chasing anything, they'd have to get the keys from America, the engine back from Turkey...

And a laptop to refuel it before it's ready to fly then they have to wake the pilot up.
