The History channel ran a great show about Tesla a week or so back.
He could invent at will. When Edison threw a tantrum over the world’s fair using Tesla’s AC power he refused to let them use his light bulbs so Tesla simply came up with another version.
Marconi gets the credit for the radio but Tesla got the patent in the end.
He always struck me as being ‘not of this world’.
[and no, none of the “ancient aliens” crap]....LOL
