I've often wondered about what Tesla was smoking when he came up with the most amazing inventions and innovations of his era...his claims of having invented a directed energy beam for example(the secrets of which seem to be lost or suppressed, more likely)....
Don't know much about Tesla besides the usual. He holds, or his name is on, many of the basic electric patents. His generators at Niagara are still in operation. I'm sure that some of his conjectures were fruitless, its very common for creative people to have a lot of ideas, some of which are totally off the wall. His intuitions of electrical phenomena were radical in his day.
