Joseph Westley Newman (July 2, 1936 – March 6, 2015) was an American inventor and author who developed an "energy machine" which he attempted to patent, but was rejected by the US Patent and Trademark Office on grounds of being a perpetual motion machine.
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 ...
[132] to take azimuths, altitude, time and declination while making observations [failed verification] Also known as an altitude Instrument, the equatorial sextant was first invented and made by William Austin Burt. He patented it in November 1856, in the United States as U.S. patent #16,002. [133] 1857 Toilet paper (mass-produced and rolled)
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 ...
