  2. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    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 ...

    en.wikipedia.org/wiki/Moses_G._Farmer

    At the age of 39 while living in Salem, Massachusetts, he lit the parlor of his home at 11 Pearl St with incandescent lamps, the first house in the world to be lit by electricity. He was a co-inventor of the self-exciting dynamo, an electric generator using electromagnets for the field which are energized by the generator output, in 1866. [ 5 ]

    en.wikipedia.org/wiki/Woolrich_Electrical_Generator

    The Woolrich Electrical Generator, now in Thinktank, Birmingham Science Museum, England, is the earliest electrical generator used in an industrial process. [1] Built in February 1844 at the Magneto Works of Thomas Prime and Son, Birmingham, [2] [3] to a design by John Stephen Woolrich (1820–1850), it was used by the firm of Elkingtons for commercial electroplating.

  5. Homopolar generator - Wikipedia

    en.wikipedia.org/wiki/Homopolar_generator

    A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim (or ends of the cylinder) with an electrical polarity that depends on the direction of ...
