THE VISIONS OF TESLA - When Nikola Tesla saw a drawing of Niagara Falls as a boy he told his uncle he’d place a wheel underneath to harness its power. He went to university but didn’t finish, before immigrating to America from Europe in 1884. Tesla found work quickly at Thomas Edison’s laboratory, often interacting closely with the brilliant inventor. Edison’s electrical system, based on direct current power (DC), was supplying light to homes in Manhattan but its reach was limited to a mile. Not long after leaving Edison, Tesla showed his alternating current (AC) motor design to George Westinghouse, another captain of industry. AC waves have gaps between the peaks, transmitting a secondary wave to fill in, thus switching directionality back and forth. A vision of AC came to Tesla in the form of a picture, allowing him to see the transmission of power over long distances. Meanwhile, Edison was shut out of the company he founded (Edison Electric) and further humiliated with a name change to General Electric. When Niagara Falls was harnessed as a power source in 1896 as Tesla predicted, General Electric dropped DC which obliterated it forever. Even today, AC is still the standard. Tesla’s ideas surpassed what he was able to accomplish in his lifetime. Particle beam weapons, the Tesla coil, radio antennas, the quark, remote control, neon/ fluorescent lights, X ray, seismic activity, radar and atmospheric energy transmission. Tesla demonstrated the principles behind the radio nearly ten years before Guglielmo Marconi. Radio patents were issued to Tesla, then reversed to Marconi, only to be posthumously credited back to Tesla. Westinghouse convinced Tesla to foolishly give up his patents early on during the AC/DC energy wars. At the age of 86 in 1943, Tesla died penniless, the recipient of more than 800 patents. Science looks to his notebooks for new discoveries to this day.
