Excellent article, BTW.
Especially if you don't mind them leaving out the part of Tesla making millions of dollars with George Westinghouse, because that would ruin their angle of slamming president Bush and capitalism in general.
Really? It wanders off into looney-left land by the end.
That said, Tesla was really the great inventor of the 19th and 20th century: all those inventions, radio, radar, AC current, listed were done essentially solo.
Edison, OTOH, really had only one great invention to his personal credit (ironically one almost never mentioned, and by far his most influential): the industrial research laboratory, and from his, the very first, came the light bulb, the phonograph, . . .
