Engineering Marvels The use of Alternating Current in the World Columbian Expo convinced investor J.P. Morgan, a former supporter of Edison, to fund the construction of Tesla's and Westinghouse's power plant at Niagara Falls. Built in 1895, it could transmit power an astonishing 25 miles away, using Alternating Current of course. Tesla eventually established his own laboratory to experiment with a multitude of physical phenomena. He would give tours of his lab to the public, light lamps by electrifying the air or allowing electricity to flow through his body, all in an effort to assuage the fear of AC power. In 1891 he created his most iconic invention, the Tesla coil, whos application is widely used in today's modern world.  This year also marked the date of his US Citizenship.                        J.
