How far are you wanting the power to go? I've read some preliminary stuff on it (and then there is the stuff Tesla is supposed to have done), but most of it is very short range.

The most common method is induction, which is a very short ranged method. Toothbrush chargers come to mind.

RFID also uses the method. The passive receiver takes enough energy from the signal carrier that it can send back data. That is usually over a range of 1 meter.
