Oh, well I get what you mean by not emitting radio waves, but isn't the reason some companies, such as Nokia have made energy efficient chargers that stop sending electicity to the device when it's fully charged is because before such chargers there have been a lot of whats called "ghost electricity", that is what it's called, right? Like even when HDTVs are turned off they are still drawing power. Oh but that can't be harnessed because it isn't be emitted. Well theres gotta be a way to get more energy out of the air some how, maybe that's too far off of a tech for our generation.
