  3. Gravitation water vortex power plant - Wikipedia

    en.wikipedia.org/wiki/Gravitation_water_vortex...

    A schematic presentation of a gravitation water vortex power plant, showing the turbine in yellow. The gravitation water vortex power plant is a type of micro hydro vortex turbine system which converts energy in a moving fluid to rotational energy using a low hydraulic head of 0.7–3 metres (2 ft 4 in – 9 ft 10 in). This technology is based ...

  4. Kelvin water dropper - Wikipedia

    en.wikipedia.org/wiki/Kelvin_water_dropper

    The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's thunderstorm.

  5. Superconducting electric machine - Wikipedia

    en.wikipedia.org/wiki/Superconducting_electric...

    Because they are light-weight and therefore offer lower tower and construction costs they are seen as a promising generator technology for wind turbines. With super conducting generators the weight and volume of generators could be reduced compared to direct drive synchronous generators, which could lead to lower costs of the whole turbine. [ 2 ]

  6. Archimedes' screw - Wikipedia

    en.wikipedia.org/wiki/Archimedes'_screw

    The screw pump is the oldest positive displacement pump. [1] The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. [1] [3] The Egyptian screw, used to lift water from the Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation.

  7. Supercritical steam generator - Wikipedia

    en.wikipedia.org/wiki/Supercritical_steam_generator

    A supercritical steam generator is a type of boiler that operates at supercritical pressure and temperature, frequently used in the production of electric power. In contrast to a subcritical boiler in which steam bubbles form, a supercritical steam generator operates above the critical pressure – 22 megapascals (3,200 psi ) and temperature ...

  8. Gravity battery - Wikipedia

    en.wikipedia.org/wiki/Gravity_battery

    Pendulum clock driven by three weights as "gravity battery". An old and simple application is the pendulum clock driven by a weight, which at 1 kg and 1 m travel can store nearly 10 Newton-meter [Nm], Joule [J] or Watt-second [Ws], thus 1/3600 of a Watt-hour [Wh], while a typical Lithium-ion battery 18650 cell [2] can hold about 7 Wh, thus 2500 times more at 1/20 of the weight.
