I believe a Mr Nikolai tesla demonstrated this, although the stories/evidence has been completely distorted by the frindge science community, so no-one really knows just how 'true' it is. I have seen well documented experiments from the 80's transmitting 500mW over 30 feet usiong small resonant coils with surprising efficiency. Same principles as those MIT guys, the idea of using resonance is nothing new, it hasn't changed in years, just being taken more seriously now...still I do'nt think they'll be any major advances any time soon.
