The experiment was done with a distance of 300 feet. I will dig up some pictures. Yes, it is for real. And, the MIT wireless energy is very inefficient. They can claim nothing.

Also, yes, if the source is on, it is wasting electricity. It is resonant transfer, that primary coil has to continually be on and resonating for it to put out an electric field.
