Hundreds of companies are investing in electricity transferred through magnetic fields.
Nikola Tesla, the inventor and rival to Thomas Edison, in the early 1900’s built the Wardenclyffe Tower, a 187-foot-high structure on Long Island, which he said could transmit electricity wirelessly. Financier J.Morgan backed the Wardenclyffe Tower. The project failed, and Tesla ended up broke. (In an earlier experiment in Colorado, Tesla had wirelessly lit up 200 lamps over a distance of 25 miles, but pedestrians witnessed sparks jumping between their feet and the ground, and electricity flowed from faucets when turned on. Oops.)
