How to make a fuelless generator?

Can anyone make a more detailed tutorial of this http://www.youtube.com/watch?v=jz14eOgTKDY

1. Four Germanium Diodes (1N34).
2. Two 100µF 50V electrolytic capacitors.
3. Tw0 0.2µF 50V ceramic capacitors.
4. Some kinda antenna

The circuit plan is at the end of the video.

Can anyone make a video and show the exact steps to create this? And If possible to on a larger scale.

I think I've got the parts for this. I don't expect something like this to produce very much power, but who knows? If and when I get anything, I'll reply to this thread, and it will include pictures, but not video, because I'm not really set up for video yet.
I put the circuit together, but so far I'm not getting much power out of it. But I think its working. When I short those two electrolytic caps on the output, the voltage across the same will go to zero. Then after removing the short, the voltage will build back up again, indicating that energy is flowing into the capacitors. Link to high-res version of that picture:

The antenna is made of a piece of wire, insulated 22 AWG, stranded copper.  It is about 2 meters long, and I strung it up here in lab/mancave, just sort of in the middle of the room.  Actually one end is tied to one of the ethernet cables I've got strung across the ceiling  here.  It's kind of a mess in here.  It was hard to find a good place to put the antenna.

How much energy?  Well if you look closely at the voltmeter, it's displaying about 30 millivolts (mV).  That's voltage not energy. The amount of energy stored in a 50 uF capacitor with 30 mV across it, is U=0.5*C*V2 = 22.5e-9 J, about 20 nanojoules in the two big caps. 

But how much power?  Well, the voltmeter has a input resistance of about 106 ohms, or 1 megaohm.  If that resistance has a steady voltage of 30 mV across it, then that's P= V2/R = (30e-3)^2/(1e6) = 9.0e-10, or roughly 1 nanowatt.

And that jives roughly with the amount of time it takes the caps to charge back after I short them.  It takes about 10 to 20 seconds, and that's about what you'd expect for 1 nanowatt to integrate into 20 nanojoules.

Not sure if you're familiar with the units, but a nanowatt is not enough power to light an LED with.  You know it's really nothing to write home about, or tell the shareholders about.

However, the size, shape, and placement of the antenna are going to be a significant part of the problem for something like this.  Tomorrow I'll try it outside with a bigger antenna, and see if I can't get any more power out of it.

Thanks a lot for this!

Could you make and instructable about it so that I can set one up?
I still have not managed to get this circuit to produce usable amounts of power, so I don't yet consider myself to be an expert on the subject.

However, I was thinking I had seen this circuit before, and I found this reference:

At least now I've got a good name for that circuit.  It's a Tate power converter, or a Tate Ambient Power Module, or APM, or something like that, unless someone else can find an earlier reference.

The word is futile, not fuelless.

Energy isn't a free option. All the energy and mass there is was generated at the big Bang when the universe as we know it started.

We can convert one kind into another, heat into electricity for example. But you can't a) just make it

b) suck it out of the air for nothing without upsetting someone who has put that energy there at great expense (example transmitter radio energy or tapping into the field energy from electricity pylons.)

These people tend to guard their products and get upset if you steal it.

The video is a scam. or violates someone else's product ie. transmitted energy.

About the best you could do is link an electrical generator to a bike wheel and harvest your muscle energy.

Or grow a crop that can be burned ( for example Coppicing willow trees)

converted to alcohol that can also be burned - produce heat to make steam and run a turbine driving an electrical generator.

that's about as "free " as you can get.

Something like this? http://www.youtube.com/watch?v=LFu-s6ZmGyE Thanks for the info.
Your link doesn't lead to a specific video?

Pause and think: if this works, why do you not know anybody who has already done it?
Luna Ivanova (author)  Kiteman4 years ago
A lot of people tried it, I searched on forums, but It was only written and way to complicated, but it worked, so I'm asking a video demonstration...
See the other comments - free energy is always a scam, and this idea only gathers a tiny voltage and minuscule current.

This does gather "electricity from the air" but the video is a hoax. The amount of power you can gather is just a few milli-volts. If you use a long wire antenna you get enough to power a crystal radio using sensitive head phones.

Nope sorry.

Actually you can drag energy out of the air - This tends to

a) upset the radio stations you are blacking out

b) Upset the power distribution people who quickly track you down.

Not a good idea.

Well, is there anyway to make something similar using different techniques?
Any tutorial or site you could suggest?
