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 ...

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
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]
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 ...
The Van's Aircraft RV-14 is an American aerobatic kit aircraft designed by Richard VanGrunsven and produced by Van's Aircraft. It was introduced at AirVenture in July 2012. [ 1] The aircraft is supplied as a kit for amateur construction. [ 3][ 4] As of November 2022, 207 RV-14s have been completed and flown. [ 2]
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.
a charge controller for charging the batteries or other energy storage. For converting DC battery power into AC as required for many appliances, or for feeding excess power into a commercial power grid: an inverter or grid-interactive inverter. The whole is also sometimes referred to as "power conditioning equipment".
