In 1896, at age 39, Nikola Tesla was at about the time his inventions were being used to create hydroelectric power at Niagara Falls. According to the story, the idea for the AC motor was drawn on the ground during a walk with a friend. He is shown drawing three sine waves that are out of sync by 120 degrees, the revolutionary idea that created AC electricity. Those waves flow out and into the real foundation beneath him, the AC motor. That idea became the foundation of every motor and generator to this day.
