A video of Abundant Renewable Energy's ARE 442 wind turbine. Text Version

As part of the National Renewable Energy Laboratory and U.S. Department of Energy (NREL/DOE) Independent Testing project, NREL tested Abundant Renewable Energy's ARE 442 turbine at the National Wind Technology Center (NWTC). The ARE 442 is a 10-kilowatt (kW), three-bladed, horizontal-axis upwind small wind turbine. It has a hub height of 30.9 meters and a rotor diameter of 7.2 meters. The turbine has a single-phase permanent-magnet generator that operates at variable voltages up to 410 volts AC.
