What some jolly clever chaps at MIT are talking about now, though, is
broadcasting power over distances over several metres using "coupled resonance". Basically the idea is that you have a transmitter and a receiver which resonate at the same RF frequency. They claim that power stored in the transmitter will "tunnel" to the receiver via some type of quantum coupling effect. That's what I have issues with - great if it works (wireless charging of laptop PCs, for example) but I have severe doubts about it from a purely theoretical viewpoint. I hope I'm wrong
