Before knocking this, do some research. His theories are all based on scientific fact, and sound research.
Probably one of the greatest geniuses in the field of electrical engineering.
Not only electrical engineering.......his Tesla turbine showed great potential, is amazingly simple and efficient. It impressed everyone except Westinghouse who felt it was vastly inferior to their big heavy and in-efficient turbine (the ones still in generation plants today.)
Wrong on the first point, right on the second. Tesla was like Michaelangelo or Jules Vern. He was a man out of his time and so far ahead of his contemporaries that his ideas could not have been based on research which implies prior art. "Everyone" knew how to build an AC generator (alternator) but so what "everyone" also knew that an AC motor was a physical impossibility! So much for fact and research, Tesla when told that it wasn't possible, sat down and designed the worlds first polly-phase induction motor in an afternoon. His ideas sprang from his mind as might a vision, fully formed.
Your second point is correct as stated with the possible exception of "one of". He was the man who invented the twentieth century. Without his poly-phase AC power distribution system, we would be looking at power plants spaced at twenty mile increments in both directions over the entire US. If you wanted to use Edison's DC that is.
