I have to admit that I'm very skeptical of this.
On the other hand, it is quite possible to harvest energy (though very small amounts) from an antennae. You're basically harvesting atmospheric static electricity, and you can even power very tiny motors with it. I've measured voltage difference on wire fences, basically the same thing. The problem is, though, is that it takes an extremely LARGE antenna to harvest usable energy. I think I found that a 1/4 mile barbed wire fence might be able to produce enough energy to light one LED.
I'd be more inclined to believe this sort of thing if there were independent, verified tests of the contraptions
So, someone build one, and let us know how it works.
