2.4ghz on a Wifi connection isn't much different. This'd depend on the power & frequency of the signal, at any constant point, as to whether it'd cook anyone's innards or shake them to bits. Which, apparently, it wouldn't at that frequency.

Wireless power is already halfway there, though - see the 'Splashpower' device. The MIT plan is, essentially, to upgrade the technology to a 3D field rather than a semi-connected 2D surface. Think of it as like putting a microphone near a speaker, but with electrical rather than sound energy.

@David R: Forget about scaling it up, how about computer chips & motherboards without PCBs & other electrical conduits? No resistance, either.
