Thomas Edison built his fortune on direct current, wiring the first power plants around incandescent lamps and motors he already controlled the patents for. George Westinghouse bet on alternating current instead, and hired Nikola Tesla, whose grasp of mathematical physics gave him a working system for generating, transmitting, and using AC over long distances. This student-made history documentary lays out the late-1880s fight between the two camps: Edison's insistence that DC was safer and more reliable, Westinghouse and Tesla's case that AC could travel farther and cheaper, and the personal grievance underneath it, since Tesla had worked for Edison and left after being denied pay he says he was promised. The film treats the rivalry as a business and engineering dispute as much as a personal one, tracing why AC eventually became the standard despite Edison's public campaign against it. It won third place in the Colorado History Day 2010 senior individual documentary category, and stays close to that competition format: plain narration, direct claims, no reenactments.
