RE: My DIY radio wave energy harvesting circuit
I recently read about a company that is transferring power via waves between 1-5m. There must be some wave range where this works quite well then. Dont remeber where it was.
Wireless power definitely works, but it's usually pretty inefficient. After writing this I had the idea of using this harvester as an RF detector by adding an LED that lights up when it gets close to something transmitting by using energy in the storage capacitors. This would let you detect stuff like FM transmitters without seeing them. I'm going to try to throw it together and make a post in a few days about it if you're interested.
