-Teleforce [deathray, particle ray that would destroy armies & all the airplanes in the air. "But it is not an experiment... I have built, demonstrated and used it. Only a little time will pass before I can give it to the world." ]
-Free Energy. [wikip claims that he meant "utilizing untapped natural sources," but the line's pretty hazy, he was describing harnessing "energies" like gravitational fields]
Here's my earlier post dealing with these two points

-Force Field: a Scalar field dome made of energy that will eventually be built big enough to protect a city from attack during wars.
-Tesla's Flying Machine: cigar-shaped. Nuff said.
-Tesla's car powered by cosmic energy -- a hoax having nothing to do with Tesla, that his loony admirers nevertheless attribute to him. See here.
-Thought Camera
here, though wikip is really shaky on Tesla. Some stuff pruned/some added.
I'm not sure what sort of citations you expect. I can certainly give you Wikip links, would you be happy with that? I can point you to books like "The Fantastic Inventions of Nikola Tesla," multiple biographies, and other questionable authorities. I can not otherwise document my claims without doing some serious poring through the stacks & a healthy dose of luck. If Tesla was not granted a patent for a particular "invention," what would you accept as "documentation"?
If you *are* happy with wikipedia as a source, everything i have mentioned could be found here: http://en.wikipedia.org/wiki/List_of_Nikola_Tesla_patents
Finally, i hope you have read my post in its entirety. I'm not trying to make Tesla out to be a loon. He's someone i admire.
