With the benefits of Windmills come common concerns like the whooshing sound that regular turbines produce, as well as their divisive visual aesthetics. Keeping in mind the volatility of the speed of wind in the urban environment, the QR (Quiet Revolution) has been designed. A new type of wind turbine intended to address both of these issues, Quiet Revolution’s QR5 Vertical Axis Wind Turbine, or VAWT for shawt, is smaller, quieter, and way better looking than your typical windmill, plus it should produce the equivalent of its £25,000 price tag in clean energy within 15 years or less. The elegant helical (twisted) design of QR ensures a robust performance even in turbulent winds. It is also responsible for virtually eliminating noise and vibration.

At five metres high and three metres in diameter, it is compact and easy to integrate, and with just one moving part, maintenance can be limited to an annual inspection.

Though the energy output will vary according to the wind speed but is likely to be between 6,000 and 10,000 kWhrs on a typical site. And if that wasn’t all, according the usage of such windmills will also lead to reduction in CO2 emmisions.
