these guys claim more efficiency, no noise, best use of wind even in turbulence, lowest startup speed, and no upper limit on wind strength..
"In real environment testing in the Archipelago of Finland the Windside Wind Turbine produced up to 50% more electricity in a year than a traditional propeller type turbine of the same swept area.
With the Worlds average prevailing wind speed being only 3 m/s (10.8 km/h 6.75 mph) the lower the wind speed at which the turbine starts to generate power the better. The Windside Wind Turbine range with its unique vane construction utilises wind speed as low as 1-3 m/s (3.6 km/h 2.25 mph) other turbines are still standing still at these wind speeds. At the other end of the scale the Windside Wind Turbine will continue to produce at wind speeds up to 60 m/s (216 km/h 135 mph). Both these facts are world records.
Wind speed is not the only factor to consider. Turbulence and changes in wind direction effect a turbines ability to produce power at the rate stated in ideal test conditions. Conventional propeller type turbines are slow to react to these factors. The Windside Spiral Vanes always reach the wind at the right angle "
