Let's see about the feature of this energy ball. of the hottest news recently.
The website is in Swedish, you can click here.
Max power generated is 2500 Watt for V200 (1.98 m rotor diameter, weight 90 kg) in the max wind speed of 40 m/s. The starting speed can achieve 3 m/s.
But some report say that typical wind speed in urban area is only 1.73 m/s although max wind speed can achieve 16.17 m/s. You can check the source at http://www.scoraigwind.com/citywinds/
The company claim that it can substitutes 50% of electricity consumption household, but the data is very minimum.
Good points are that it is said very silent, claimed very efficient comparing other type, the price is $4,600 for V100 and $8,100 (exclude mounting), and it can be plugged in home electric installation with the control panel.
I think they must publish the data of each wind speed for us to start using it. It is not very cheap.
