Tesla was a absolute wonder, there may or may not ever be someone like him again in history. Like many of you have said, he lacked in some marketing skills the Edison had.
The biggest problem I see with many of Tesla's inventions is that many tinfoil/conspiracy theorist types have latched onto him in a sort of "This man solved all of mankind's problems, but the evil big government/big corporations/organized religion/ect killed him because he was going to free everyone. I've seen many of his ideas replicated and they just don't work as well as people could hope. Yeah, alot of his stuff was awesome, however some of it was not, and people seem to think that someone somewhere is keeping a vault full of his magical inventions away from the public because it would destroy everyone.
The thing is, there are MANY smart people in the world. Yeah, many governments and ideologies love to try and limit the resourcefulness of people, yet people still create amazing and awesome things.
I'm curious, with all of the money and brainpower here on wickedfire why someone hasn't taken that money and done something really amazing with it, rather than build a bunch of websites or on hookers & blow in some southeast Asian country.
