Ambient Power Module - Questions & Answers

[ojsimon]

Hi

Does anyone have any experience with ambient power modules? I have a few questions, if anyone could answer any of them i would be most apreciative.
1) do they work?
2) how much power can they output?
3) how small can you make them?
4) how much could you make them for (in mass production)?

Thanks

Solar energy is the only ambient power I know of that is worth pursuing.

Edit: also wave, wind and hydro energy

If you are talking about getting power from RF signals in the air (which is what a radio receiver does) then you are only going to be able to get a few micro-watts at best. You would be better off getting power from the sun. Note, you can't get something for nothing.
