Who invented electric power?
I visited the home town of Gennai Hiraga on Japan’s island of Shikoku. According to Wikipedia, he invented “The Elekiter (エレキテル, Erekiteru?) is a Japanese invention created by Hiraga Gennai in the 1700s. It is a small box that uses the power of friction to generate electricity” in the 1700′s. He also invented the compass and thermometer. How does he compare to other inventors?
When you ask the question “Who invented electric power?”, I presume you mean the electric power distribution that we know of today.
One of the primary contributors would be Nikola Tesla, a Serbian-American electrical engineer and scientist. He along with the Westinghouse corporation developed the three-phase AC power distribution used around the world today. Tesla and Westinghouse corp were also heavily involved in developing new generators and motors using three-phase power. Edison was trying to promote a relatively inefficient DC distribution system at the same time, but failed to gain widespread support. Though Edison did create inventions, such as the light bulb, that helped make use of the ever-growing power grid.
I had not heard of Gennai Hiraga before, but sounds like a pretty interesting inventor as well.
