July 10th is the birthday of Nikola Tesla, the man who invented the most widely used power transmission system in the world today; the alternating current (AC). This year will be his 162nd anniversary. To commemorate his birthday and celebrate his accomplishments, we have consulted authoritative and objective sources to bring you documentation of the clash between him and his foremost archrival, Thomas Edison, who invented direct current (DC). Both men were accomplished inventors who transformed the world of electricity, but they had strong opposing views on the preferable mode of transmitting it, with each man rooting for his method. When you have power wars between two famous legends, expect sparks, fireworks, and even a real fire.
