Quietrevolution wind turbine

Quietrevolution wind turbine

The Quietrevolution is a brand of (VAWT) vertical axis Darrieus wind turbine which has won several awards including the "Sustainable Innovation Award" in 2006. There are proposals to use the turbine in projects in New York and Shanghai.

The turbine consists of three vertical aerofoil blades which have a helical twist of 60 degrees, almost similar to Gorlov's water turbines. Since the wind pulls each blade around on both the windward and leeward sides of the turbine, this feature spreads the torque evenly over the entire revolution, thus preventing the destructive pulsations of the straight-bladed giromill.

The QR5 6kW turbine measures 3.0m in diameter by 5m high. A 2.5kW model is in development.
