Windstar Turbine
The Windstar vertical-axis turbine is a lift-type device with straight blades attached at each end to a central rotating shaft. Windstar turbines were invented by Robert Nason Thomas and developed by Wind Harvest International, Inc., formerly the Wind Harvest Company, based in Point Reyes, California. Windstar turbines are operated as Linear Array Vortex Turbine Systems (LAVTS). Each rotor unit has a dual braking system of pneumatic disc brakes and blade pitch. All Windstar models use off-the-shelf generators, gearboxes, bearings and other components.
