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 ...
A bolometer measures the energy of incident electromagnetic radiation. It was invented in 1878 by American astronomer Samuel Pierpont Langley. [229] 1879 mechanical production of Photographic plate. Photographic plates preceded photographic film as a means of photography. A light-sensitive emulsion of silver salts was applied to a glass plate.
Another more complicated belt machine was invented in 1903 by Juan Burboa. [1] [5] A more immediate inspiration for Van de Graaff was a generator W. F. G. Swann was developing in the 1920s in which charge was transported to an electrode by falling metal balls, thus returning to the principle of the Kelvin water dropper. [1] [6]
"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 ...
John Ernst Worrell Keely (September 3, 1837 – November 18, 1898) was an American fraudster and self-proclaimed inventor from Philadelphia who claimed to have discovered a new motive power which was initially described as "vaporic" or "etheric" force, and later as an unnamed force based on "vibratory sympathy", by which he produced "interatomic ether" from water and air.
Tesla's electro-mechanical oscillator is a steam-powered electric generator patented by Nikola Tesla in 1893. [ 1 ] [ 2 ] Later in life, Tesla claimed one version of the oscillator caused an earthquake in New York City in 1898, gaining it the colloquial title "Tesla's earthquake machine ".
2009 (): On August 26, 2009, Team Inspiration broke a second record by setting a new speed record of 148.308 mph (238.679 km/h) over a measured kilometer. [26] Steam turbines are made to 1,500 MW (2,000,000 hp) to generate electricity. [27]
1663 – Otto von Guericke: first electrostatic generator; 1676 – Ole Rømer: Rømer's determination of the speed of light traveling from the moons of Jupiter. 1678 – Christiaan Huygens mathematical wave theory of light, published in his Treatise on Light; 1687 – Isaac Newton: Newton's laws of motion, and Newton's law of universal ...
