George Westinghouse was an amazing American who changed the world. He invented the air brake for trains. Until this invention, only locomotives had brakes and thousands died annually in train wrecks. Every train in the world today still uses his system. In addition, the AC power used all over the world was pioneered by Westinghouse. Edison wanted to use DC power because he could make more money but Nikolai Tesla convinced Westinghouse that AC was better . His impact on the world was huge.
Nikola Tesla and George Westinghouse - With the big money supporting DC currents (Edison Electric, J.P. Morgan, Thomson-Houston Company - through a merger into G.E. General Electric), Pittsburgh magnate George Westinghouse stood by Tesla's AC current, because as an inventor himself, he knew that the technology was superior, and felt that it would eventually win the war of the currents. Tesla, amazingly, would later give up his $2.50 per horsepower of electrical capacity sold that he was due.
The Inventor George Westinghouse and His Influence on Electricity
In what is considered the first industrial use of alternating current in 1891, workmen pose with a Westinghouse alternator at the Ames Hydroelectric Generating Plant. This alternator was used as a generator producing 3000 volt, 133 Hertz, single-phase AC.
