Maybe it would be possible for the emitter/primary to know there is a receiver/secondary around drawing power from it, if none it could turn off, and turn on for a brief time every few seconds to check of it's needed. Maybe it could even modulate its output power to fit the needs?
On the "how it works" side, has anybody understood the difference between this MHz "resonant magnetic coupling" device and a radio emitter with a tuned receiver? They say energy is not radiated away if it's not used by a receiver, I can't really see why.
