  2. Small wind turbine - Wikipedia

    en.wikipedia.org/wiki/Small_wind_turbine

    Small wind turbines, also known as micro wind turbines or urban wind turbines, are wind turbines that generate electricity for small-scale use. These turbines are typically smaller than those found in wind farms. Small wind turbines often have passive yaw systems as opposed to active ones. They use a direct drive generator and use a tail fin to ...

    en.wikipedia.org/wiki/Wind_turbine

    A forerunner of modern horizontal-axis wind generators was in service at Yalta, USSR, in 1931. This was a 100 kW generator on a 30-meter (98 ft) tower, connected to the local 6.3 kV distribution system. It was reported to have an annual capacity factor of 32 percent, not much different from current wind machines. [citation needed]

  6. Pico hydro - Wikipedia

    en.wikipedia.org/wiki/Pico_hydro

    Pico hydro. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes. [ 2] Even smaller turbines of 200–300 W ...

  7. Vortex generator - Wikipedia

    en.wikipedia.org/wiki/Vortex_generator

    A vortex generator ( VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface (or airfoil, such as an aircraft wing) [1] or a rotor blade of a wind turbine. [2] VGs may also be attached to some part of an aerodynamic vehicle such as an aircraft fuselage or a car. When the airfoil or the body is in motion ...

    en.wikipedia.org/wiki/History_of_wind_power

    By 500 AD, windmills were used to pump seawater for salt-making in China and Sicily. [24] Wind-powered automata are known from the mid-8th century: wind-powered statues that "turned with the wind over the domes of the four gates and the palace complex of the Round City of Baghdad". The "Green Dome of the palace was surmounted by the statue of a ...
