@Avendarito,
Quote: He invented; AC current without such only the rich would have electricity.
Tesla DID NOT invent AC current. AC was in use in Europe 30 years before Tesla put together his three phase AC motors . Westinghouse was a proponent of AC before he even hired Tesla and Tesla joined Westinghouse after working for Edison and getting screwed out of a promised bonus for redesigning muchof Edisons DC equipt. The "current wars" are well documented nd you should read about them before landing on an incorrect asserion.
Tesla was relly bright guy, but like many developers, he stood on the shoulders of others who broke the ground first.
