A bit more detail on Tesla
No one will deny that Tesla was a genius. I stand in awe of everything that he gave us. IMO, the reason he is not better known is that Americans don't admire a genius per se; we admire a genius who can make a buck off his smarts and retire a billionaire (or, back then, a millionaire). Tesla was foolish with money, in a way that Edison was not.
Even so, it has been over a century since J.P. Morgan killed Tesla's Wardenclyffe project. It was not just Tesla's fantastic claim of inventing wireless power transmission, nor his flippant dismissal of Morgan's question of where to put the meter. Morgan had been concerned for some time about Tesla's money pit on Long Island, and his inability to explain its purpose. In 1904, no one knew what to make of a "World Broadcasting Center"; even those who understood the new development of radio technology conceived of it as wireless telegraphy: a means of point-to-point transmission. The world would take another two decades to catch on to the real implications.
There have been countless other geniuses since Tesla. If Tesla really was on to wireless transmission of power in 1904, why hasn't anyone else picked it up until "now"?
BTW, 40% transmission efficiency is dismal!
