Quiet Revolution’s QR5
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.
