Regarding the "wasted" power that is broadcast into oblivion, I do not think the technology works that way. The transmitter and receiver are resonant, so nearly all (well, more than 50%, anyway) of the transmitter power ends up in the receiver. My recollection is that Soljacic believes that efficiencies on the order of 75% are achievable. This is fairly respectable for a power supply, with 60% efficiency not uncommon in consumer electronics.
