    The patent application filed in July 1887. His first generator of this type went into operation in October 1887. [26] [27] 1887, Charles S. Bradley Motor/generators with a Gramme ring, having multiple radial connectors, led off at corresponding symmetrical points to slip-rings. He thus obtained alternate currents differing in phase.

    Robert Fludd's 1618 "water screw" perpetual motion machine from a 1660 wood engraving.It is widely credited as the first attempt to describe such a device. [note 1] [1] Something for Nothing (1940), a short film featuring Rube Goldberg illustrating the U.S. Patent Office's policy regarding perpetual motion machines (and the power efficiency of gasoline)

  5. Wimshurst machine - Wikipedia

    en.wikipedia.org/wiki/Wimshurst_machine

    The Wimshurst machine or Wimshurst influence machine is an electrostatic generator, a machine for generating high voltages developed between 1880 and 1883 by British inventor James Wimshurst (1832–1903). [citation needed] It has a distinctive appearance with two large contra-rotating discs mounted in a vertical plane, two crossed bars with ...

  6. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    In electricity generation, a generator[1] is a device that converts motion-based power (potential and kinetic energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even ...

  7. History of electric power transmission - Wikipedia

    en.wikipedia.org/wiki/History_of_electric_power...

    Electric power transmission, the tools and means of moving electricity far from where it is generated, date back to the late 19th century. They include the movement of electricity in bulk (formally called "transmission") and the delivery of electricity to individual customers ("distribution"). In the beginning, the two terms were used ...

  8. Motor–generator - Wikipedia

    en.wikipedia.org/wiki/Motor–generator

    A motor–generator (an M–G set) is a device for converting electrical power to another form. Motor–generator sets are used to convert frequency, voltage, or phase of power. They may also be used to isolate electrical loads from the electrical power supply line. Large motor–generators were widely used to convert industrial amounts of ...

    en.wikipedia.org/wiki/Franklin's_electrostatic...

    Franklin's electrostatic machine is a high-voltage static electricity - generating device used by Benjamin Franklin in the mid-18th century for research into electrical phenomena. Its key components are a glass globe which turned on an axis via a crank, a cloth pad in contact with the spinning globe, a set of metal needles to conduct away the ...
