The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all the power for electrical grids . In addition to electricity- and motion-based designs, photovoltaic and fuel cell powered generators use solar power and hydrogen-based fuels, respectively, to generate ...
1893 (): Nikola Tesla patents a steam powered oscillating electro-mechanical generator. Tesla hoped it would become competitive with steam turbines in producing electric current but it never found use outside his laboratory experiments. 1897 (): Stanley Brothers begin selling lightweight steam cars, over 200 being made.
German scientist Otto von Guericke invented a device that creates static electricity. This is the first ever electric generator. 1705: English scientist Francis Hauksbee made a glass ball that glowed when spun and rubbed with the hand 1720: English scientist Stephen Gray made the distinction between insulators and conductors. 1745
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
Commercial popcorn machines are usually found in movie theaters and carnivals, producing popcorn of the oil-popped type, which has approximately 45% of its calories derived from fat. The first commercial popcorn machine was invented by Chicago resident Charles Cretors in 1885. His business that he founded, C. Cretors & Company, still to this ...
Chicago Pneumatic is a brand name in the pneumatic tool industry with a history tracing back to 1901. John W. Duntley had in mind the idea of sourcing and selling construction tools "that weren’t yet available". He established the Chicago Pneumatic Tool Company, [5] with an office in Chicago.
Steam turbine generator: The first commercial Westinghouse steam turbine-driven generator, a 1,500 kW unit, began operation at Hartford Electric Light Co. in 1901. The machine, nicknamed Mary-Ann , was the first steam turbine generator to be installed by an electric utility to generate electricity in the US.
Van de Graaff was the inventor of the Van de Graaff generator, a device which produces high voltages. During 1929, he developed his first such generator, producing 80,000 volts. [6] By 1933, he had constructed a larger generator generating 7 million volts. [6]
