  2. Free-piston engine - Wikipedia

    en.wikipedia.org/wiki/Free-piston_engine

    Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).

  3. Newman's energy machine - Wikipedia

    en.wikipedia.org/wiki/Newman's_energy_machine

    Newman's energy machine. Newman's Energy Machine was a DC motor which the inventor, Joseph Newman, claimed to produce mechanical power exceeding the electrical power being supplied to it. In 1979, Newman attempted to patent the device, but it was rejected by the United States Patent Office as being a perpetual motion machine. [1]

  4. Earth battery - Wikipedia

    en.wikipedia.org/wiki/Earth_battery

    An earth battery is a pair of electrodes made of two dissimilar metals, such as iron and copper, which are buried in the soil or immersed in the sea. Earth batteries act as water-activated batteries. If the plates are sufficiently far apart, they can tap telluric currents . [citation needed] Earth batteries are sometimes referred to as telluric ...

    en.wikipedia.org/wiki/Stirling_engine

    The Stirling engine (or Stirling's air engine as it was known at the time) was invented and patented in 1816. [ 19 ] It followed earlier attempts at making an air engine but was probably the first put to practical use when, in 1818, an engine built by Stirling was employed pumping water in a quarry. [ 20 ]

  6. Free-piston linear generator - Wikipedia

    en.wikipedia.org/wiki/Free-piston_linear_generator

    The free-piston linear generator (FPLG) uses chemical energy from fuel to drive magnets through a stator and converts this linear motion into electric energy. Because of its versatility, low weight and high efficiency, it can be used in a wide range of applications, although it is of special interest to the mobility industry as range extenders for electric vehicles.

  7. Monotube steam generator - Wikipedia

    en.wikipedia.org/wiki/Monotube_steam_generator

    Monotube steam generator. Herreshoff steam generator in a Peruvian torpedo boat of 1879. A monotube steam generator is a type of steam generator consisting of a single tube, usually in a multi-layer spiral, that forms a once-through steam generator (OTSG). The first of these was the Herreshoff steam generator of 1873.

    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 ...
