In theory, wireless transmission of electrical energy is possible, again that is per Tesla's experiments. Now what he is saying is frequencies around us is making the electricity on his motor with a help of a generator that he built then we should really look into this. Technically it is possible, talk to any ece guy and they will tell you it is very likely. But the amplification of that frequency into some extent really amazes me. Watch mode muna ako until he reveals the architectural frame of his generator.
