Wind Turbine for Urban Environment

The quietrevolution QR5, a helical wind turbine made for the urban environment, will soon be available in the United States. The twisted blades are designed to eliminate noise and vibration while capturing turbulent, shifting winds. The QR5 has only one moving part, making it easier to maintain. At five meters high and three meters in diameter, the turbine will integrate with many types of structures. The product will be displayed at the Wired NextFest in New York from September 27th to October 1st.
