It doesnt take a stretch of the imagination to think that if indeed "free energy to the people" (of which Tesla was intent on) was possible, that powerful companies who sell energy would seek to suppress or discredit this information, as Edison did from the start to protect his DC system. Perhaps evidence enough of this can be found by Tesla's withdrawal of financial backing, social isolation and systematic exclusion from the history books. Its easy enough to discount someone publicly as a "madman". but interest in his research by both the US and the soviets after his death suggest otherwise...
Its worth checking out research by Lt. Col. Thomas E. Bearden, you can torrent his 1988 lecture
TESLA'S SECRET AND THE SOVIET TESLA WEAPONS and also numerous docos on youtube about HAARP and weather weaponry... a lot of its pretty far fetched and way over my head, but at the end of the day, whether you believe them or not...they make you think and are often great stories :)
It would be sad to think (however awesome it is) that
this would be Tesla's only legacy ;)
