Most of the outlandish stuff you hear about Tesla comes from bad biographers who got most of their information from show bills about his acts. In his time, Inventors were presented as magicians, and so thats what they made them sound like. In reality, Tesla was a brilliant man who did a lot of amazing things, and to me the really amazing but false things you hear about him undermine his true accomplishments.
I'm not sure why people claim that 'most of his patents never saw the light of day' and that they were stolen by the government. His papers were taken from the hotel that he lived in partly because with no family in this country, there was no one to collect them. As for his patents, I have his book that he wrote (the fantastic inventions of Nikola Tesla; modest, no?) and it is largely a collection of all of his patents.
What may be confusing you is the fact that he didn't actually patent many of his inventions, since he saw them as toys for his own enjoyment, such as fluourecent lights, the discovery of plasma, the predessesor of the electron microscope (
carbon button lamp), etc. etc.
Most people latch on to some of his more outlandish ideas and tout them as having been repressed by the government or other shady illuminati-esque shadow men, but in reality they just aren't practical or feasible. Unlike what is portrayed in the prestige, you can't really just charge the ground with electricity. Tesla also described a train that would encircle the globe and would be supported by its own counter acting gravitational pull, but who would really build such a thing? Sure it would be essentially frictionless but who cares, its unwieldy as all hell.
