Legal situation?!? You're creating a matched impedance point in space. RF energy harvesting is a bit of a hot topic, there are a number of modules on the market atm. Just search for it on mouser or farnell to get started. Thanks btw for that LED schematic, so simple. I'm currently tuning a harvester around a BQ25504 and super caps. I'll give it a test next week. http://uk.mouser.com/Embedded-Solutions/Energy-Harvesting-Modules/_/N-8t3zx?P=1yzotr6 http://uk.mouser.com/Embedded-Solutions/Energy-Harvesting-Mo...
