The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.

For the sake of not getting closed down, agreed. Btw, I've read where not just dipoles, radio waves, but energy packets and photons are suspected by some of doing some strange temporal displacements. CM

I had a play around with some thermocouple wire at work this afternoon, just to find out its 'potential' as a power supply
A single junction generated a maximum of .4mV at 3uA, when I held it between my fingers. I calculated that I'd need about 41 million junctions total to light an LED like this, which I announced to my work colleagues (they weren't all that impressed).
I have an old fridge peltier here, wich can give up to 1,5V and 1amp short circuit if one side s heated by a lighter. I can power small motors that way; for LED's and etc. I would need a boost converter or series peltiers.
I can also run a motor if I heat up one side with my body heat in cold enviroment.
As heat engines, termocouples are very inefficient and hav little use, except where extreme ruggednes and no moving parts are required, as in space probe RTG's.

Just to clarify a few things:
I decided to allow waste energy as well as genuine free energy in order to make the contest easier and get more interest. This is not an attempt to solve the world's energy problems, since I don't actually believe there is any magic bullet solution to them. The problem is too many people using too many resources, and you either have to make them consume less, or get rid of them. I just want to encourage our members to build stuff, do experiments, and learn about energy.
I don't care whether Joe Tate, Tesla, or Oprah Winfrey invented that RF rectifier thing, it's just a variation on the theme of a rectenna.
Once we have enough entries, you guys are voting on who wins, not me. (remember CM is eligible to win too, since he lit an LED!)
Finally, no time travel please! Discussions of quantum mechanics and the EPR experiment are fine, since these are real science, although off topic for this thread.

If I remember correctly what I learned in electromagnetics classes, an oscillating dipole generates both a retarded and an advanced wave, the latter of which travels backwards in time. There is some stuff about this in the second volume of the Feynman lectures if anyone cares to look it up. Apparently interactions of charges (which is what sending and receiving RF is about) always require some "previous knowledge" of where the energy is going to go.
Perhaps this is where Tesla got his idea of conduction of energy rather than propgation. A source and a reciever are needed to do the test, hence little way of determining if true or not.

Yeh thanks Steve, I've read it. Who ever mentioned Tesla being shut down by oil companies? I think your judgements are unsubstatiated. Because I admit to having a soft spot for psuedoscience does not make me a conspiracy freak!

I just had a 'lightbulb hovering above head' moment
Check out this thread:-
Finally, a use for those things! Not surprisingly, I still have a whole bag of them. I just connected one up to a red LED and tapped the can with a spanner. It caused a very feint flicker of the LED. All I need to do is find a way to mount them all on a solid surface such as a block of steel, in a way whereby they will all be in phase when tapped, then I can parallel them and fullwave rectify the output with some ultrafast diodes. I suppose I could then go ahead and stick the whole array onto the washing machine or something.
Anyway I'm too lazy to do it tonight, that's why I'm just writing about it instead

I'm not trying to step on anyone's toes here, because I love all you guys as fellow designers, but I think the thread is diverging off of its intended path here.

I was trying to ignore that, but, yes, that's a fact

"A single junction generated a maximum of .4mV at 3uA, when I held it between my fingers. I calculated that I'd need about 41 million junctions total to light an LED like this, which I announced to my work colleagues (they weren't all that impressed). "
I have tried to build my own thermalcopler but only managed to generate 1mv. I would need a couple thousand of them to light an LED. I said forget it.
On the otherhand, I managed to light the LED again. Below is a 6" diameter coilform in my hand near my monitor.
Edit: I have managed to find two more sources of "free" energy.
Microwave leakage.
I have found some scrap metal and used food containers and built a battery. Yes it is free energy. These things would have gone in the trash anyway.
