QuietRevolution: Another Small Wind Design...
A new design for small scale wind turbines. This turbine is made to be very quiet, usable around buildings, easily integrated into towers and the general urban environment. Their smallest model, the QR2.5 is 2.5m in diameter. It is expected to generate between 3,000 and 4,500kWh per annum on a site with a windspeed of 4m/s as a minimum annual mean.
The Bergey BWC XL.1 Wind Turbine, which is also 2.5m in diameter, is advertised to provide 1,898 kWh per annum. Bergey is a very well known wind turbine and many consider it to be the best available for home users. Despite this it only gets 1/2 the rating as the Quiet Revolution. It will be interesting to see some real world tests of these turbines on the exact same sites.
