Quiet Revolution qr5, Windspire, Mageen Air Rotor System, Windbelt, WePOWER and Spiral Drag Wind Turbine are some designs of wind turbines. The qr5 is a helical wind turbine specifically designed for low wind speeds and changing wind directions. Unlike traditional wind turbines, it collects wind from all directions equally.
The Windspire is a vertical wind turbine that can generate 2000 kilowatts per hour of power from 12 miles per hour of wind speed. The Mageen Air Rotor System features a helium-filled airship-like body, which rotates about a horizontal axis to generate electricity. The Windbelt is an inexpensive, small-scale turbine that can generate 40 milliwatts of electricity from 10 miles per hour of wind speed.
