So, you are saying they cannot be efficient because people are not using them already? How are you on the internet? Before the 1980's there wasn't a world wide web, and according to your statement if it isn't already in use it cannot be adopted. You're retired, so you must have existed before the creation of the internet. That's just hypocritical.
I never said it would. I may use this to run some sensors though. Maybe a microcontroler.
First of all, the energy is "free" in the same way as solar is. Thomas, you seem to not understand this 'ible, and the science for that matter. You say that harvesting radio energy is "stealing" and mention (not cite btw) that legal cases have proved this. That is blatantly false. The cases you refer to are in relation to some incidents of people surreptitiously inserting inductive loops inside the field of power lines or in the path of a microwave radar dish. Please correct me if I am wrong, I found mention of these cases at http://www.industrytap.com/electromagnetic-harvest... Yes, no one is arguing that removing energy, even in a non-destructive fashion, from services that deliver energy is theft. However, this 'ible is dealing with harvesting ambient energy from the environment, as such it is not applying a load to any appreciable source. PS, There is a lot of natural noise like spacepymp said. Here's my source: http://www.progettomem.it/doc/MEM_Noise.pdf Where is your source for the statement " But What energy do you get from not-man-made RF? Almost none, since the only RF that can power a motor like he did is simply man-made."
