For what I can understand in a brief read out is that they are talking about something similar or exact to the power mat. check it put. This technology is already in place to charge cellphones and other devices.
http://powermat.com/ I believe what they use is resonant magnetic induction, but it consist of two units an emitter and a receiver. You then need time for the receiver which is like a battery to charge.

There are other methods like microwaves, laser beamming, but I just don't see how you can transmit directly at 12 volts range 2 amps without seeing some kind of spark. There is not such thing as wireless DC that I know. I may be wrong. But if this excited it would have been implemented in other tools/ households already.
