  2. Small wind turbine - Wikipedia

    en.wikipedia.org/wiki/Small_wind_turbine

    A 1 kW micro windmill installed in the suburbs of Lahore, Pakistan. 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 ...

  3. Vaneless ion wind generator - Wikipedia

    en.wikipedia.org/wiki/Vaneless_ion_wind_generator

    Sustainable energy. A vaneless ion wind generator or power fence is a device that generates electrical energy by using the wind to move charged particles across an electric field . Ion wind generators are not commercially available, though working prototypes and proofs of concept have been created.

  4. Microgeneration - Wikipedia

    en.wikipedia.org/wiki/Microgeneration

    Domestic microgeneration technologies include: photovoltaic solar systems, small-scale wind turbines, micro combined heat and power installations, biodiesel and biogas. A small Quietrevolution QR5 Gorlov type vertical axis wind turbine in Bristol, England. Measuring 3 m in diameter and 5 m high, it has a nameplate rating of 6.5 kW to the grid.

  5. Flywheel energy storage - Wikipedia

    en.wikipedia.org/wiki/Flywheel_energy_storage

    Flywheels may be used to store energy generated by wind turbines during off-peak periods or during high wind speeds. In 2010, Beacon Power began testing of their Smart Energy 25 (Gen 4) flywheel energy storage system at a wind farm in Tehachapi, California. The system was part of a wind power/flywheel demonstration project being carried out for ...

    An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub

  7. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    In a series configuration, if a single battery dies, the other batteries will not be able to power the load. Parallel configuration If the goal is to increase capacity and prolong the runtime of the inverter, batteries can be connected in parallel. This increases the overall ampere hour (Ah) rating of the battery set.

  8. History of wind power - Wikipedia

    en.wikipedia.org/wiki/History_of_wind_power

    The NASA wind turbines were developed under a program to create a utility-scale wind turbine industry in the U.S. With funding from the National Science Foundation and later the United States Department of Energy (DOE), a total of 13 experimental wind turbines were put into operation, in four major wind turbine designs. This research and ...

  9. Vertical-axis wind turbine - Wikipedia

    en.wikipedia.org/wiki/Vertical-axis_wind_turbine

    A vertical-axis wind turbine ( VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair. VAWTs do not need to be pointed into the ...
