"The day when we don't have to plug in our consumer electronics is getting closer, claim a a new startup firm named uBeam that has developed a safe way of beaming power to your devices.

Rather than using inductive charging, which has a very short effective range and usually requires that the charger and device be in close proximity to each other, uBeam uses an ultrasonic transducer to convert power from your wall socket into inaudible sound energy. On the device side, there's a battery adapter that converts the sound energy back into power to charge your batteries. The ultrasonic frequency used is well above the range that can be heard by humans or dogs."

These things always make me wonder what kind of losses do they experience?

Sorry I'm too lazy to check the link (it would probably be buried anyway).
