Buy a Sennheiser wireless headset. That is exactly the technology used to charge the headset battery.

-Wizard, I took it apart a while ago because I was going make some changes to it, however my personal life got too busy so it's sitting in my lab.
-ICE, yes 13.56 MHz is an ISM (Industrial, Scientific and Medical) which allows you to use very high power levels provided the harmonics are below (way below) a certain level. You're right about the FCC regulations, the approval cost would probably be a deal breaker... I have never dealt with trying to get this type of product approved, that is something that intentionally transmits a signal.
I also thought about using an intense light, infrared light (IR) from some high power LED's or a laser diode. There again, if you use a laser diode, you would never get it approved. The efficiency would be very low, probably around 10-15%.
I'll keep you guys informed.
