On the cutting edge of technology - The next wind energy turbine (2nd in the series)

2. QUIET REVOLUTION QR5

What It Is:
The qr5 wind turbine is designed for an urban environment with low wind speeds and changing wind directions.

How It Works:
Traditional wind turbines capture horizontal winds and rotate to follow changes in wind direction. The qr5's helical design allows the turbine to collect wind from all directions equally.

Where To Find It:
The first qr5 turbine was installed in Dagenham, a suburb of London, in March 2007. At the end of 2008, over 70 turbines had been installed throughout the United Kingdom, where each unit generates between 4000 and 10000 kilowatt-hours per year, according to the company.
