The point about the energy gathered and reused from collecting wide band RF from various emissions in the air often ignores the fact that more energy was dissipated (through losses in the form of heat, etc) creating these radio waves via radio, cell towers, etc....than you can ever collect. The net loss is always greater in a system than the gain. Such as in a transformer or SMPS...you can't never get more energy out than you put it, in fact you can't even break even (in which case you would have a lossless system). You can try to come close and closer (to breaking even) but entropy always wins. It's the way the universe works....it tends towards disorder.
Perpetual Motion and Free Energy == Usually considered and attempted by people who don't fully understand Physics. I'm not an expert either, but I understand how much testing the laws of thermodynamics have undergone during the course of the history of science.
-Brett ...ZPM's are fun for sci-fi, like in Half-Life II, or Star Trek..where you have things like the "inertial dampeners" or the "Heisenburg Compensators"... ;D
There isn't enough to do poop. Maybe a 1 mile long rhombic antenna could gather a half watt.
