On the AC electrical system alone, Tesla held 40 basic U.S. patents, which he later sold to George Westinghouse, an American engineer and business man who was determined to supply the nation with the Tesla's AC system. He would succeed in doing just that, not long after purchasing Tesla's patents. Around this time, conflict arose between Tesla and Edison, as Edison was determined to sell his direct-current system to the nation. According to the Tesla Memorial Society of New York, Tesla-Westinghouse ultimately won out because Tesla's system was "a superior technology," presenting greater "progress of both America and the world" than Edison's DC system. Outside of his AC system patents, Tesla sold several other patent rights to Westinghouse.
At the 1893 World Columbian Exposition, held in Chicago, Tesla conducted demonstrations of his AC system, which soon became the standard power system of the 20th century, and has remained the worldwide standard ever since. Two years later, in 1895, Tesla designed the first hydroelectric powerplant at Niagara Falls, a feat that was highly publicized throughout the world.
Around 1900—nearly a decade later after inventing the "Tesla coil"—Tesla began working on his boldest project yet: Building a global communication system—through a large, electrical tower—for sharing information and providing free electricity throughout the world.
