The demonstration in the video below is interesting, if not pointless:
It depicts a quadrotor toy being 'wirelessly' powered via resonant energy transfer. The toy's range is only a few inches before flying out range of the field; not terribly useful at such low magnitudes. The idea of 'wireless electricity' is not without natural precedent - after all, at high voltages and amperages, it is called lightning. The current state of 'wireless power' is advanced by devices using less power/more efficiently than in the past, not increasing the supply side.
