The thing about Tesla's wireless energy that is vastly different than what we use, his was perfectly healthy for the body in fact "rejuvenating" is what people said they felt like stand near the larger transmitters. No today we work in the lower microwave ranges and give brain cancer.
Upvoted and followed.
It is indeed completely different. Today everything is based on electro-magnetic radiation (through the air), Tesla used electrical conduction through the Earth.
