Microwaves have strong ionising radiation which excites water to generate heat. So if microwaves from your oven escape it will literally cook you from the inside out... nasty! With wireless power for RC I doubt very much the frequencies would be anywhere near that of a microwave over (although they may be on the microwave spectrum).

Just one thing Glypo, as Microwaves are Non Ironizing radiation, they don't actually 'excite' the water molecules. Ironizing radiation doesn't start until 2420million MHZ, and at this frequency the photon energy levels are approximately the same 12.4eV, (at 2.45GHz energy levels approx 0.01eV) as the energy binding electrons to atoms. And at this energy water molecules can be ionized.
Roughly the way a microwave works is at 2.45GHz the wavelength which is a couple of cm, will absorb into the product and release energy, (heat)..
