Will we ever know what happened to all of Tesla's...?

Tesla was a genius, but also a flimflam artist. A lot of his "inventions" were figments of his imagination embellished to lure investors.

Nickola tesla was a great man but the us government did take all of his Scientific Research its probly in some top secrit lib ray with climate controls and all that stuff to keep the paper alive for a long time but you probly could guess what would be on those paper i think that's how the government found how to make stelf bombers absorb radar waves but any person who studies the laws of physics could figure it out i mean their only 118 elements some kind of combination has to do something

Tesla was a great inventor and engineer, but he was no expert on modern physics. No death rays, no particle beams, no directed energy beam weapons, I'm afraid.
