In the summer of 1931, Nikola Tesla, the inventor of alternating current and the holder of some 1200 other U.S. patents, along with his nephew Peter Savo, installed a box on the front seat of a brand new Pierce-Arrow touring car at the company factory in Buffalo, New York. The box is said to have been 24 inches long, 12 inches wide and 6 inches high. Out of it protruded a 1.8 meter long antenna and two ¼ inch metal rods. Inside the box was reputed to be some dozen vacuum tubes -- 70-L-7 type -- and other electrical parts. Two wire leads ran from the box to a newly-installed 40 inch long, 30 inch diameter AC motor that replaced the gasoline engine.

We will, of course, probably never know how he powered the car, or even if the event actually took place -- though we know Tesla was an unparalleled genius when it came to understanding electromagnetism and how to apply it for benign and some allege, deadly purposes. Legend has it that he actually invented a death ray of some type and this is why the government, on his death in 1943, is said to have confiscated all his personal papers. Presumably, they didn't want his research falling into the wrong hands… or was it because they didn't want the world to figure out how to propel our vehicles on free energy? read more at evworld.com
