Noise:
The way of the turning of the blades is of horizontal and the design of the blade is of the scheme of the wing of the air-plane, so in operation the VAWT will not make any noise. Capacity of wind resistance:
Due to the advantage of the design of the VAWT, the press force the turbine suffered is minimized and as the result such VAWT can stand on the extra strong typhoon of 50 m/s.
Space requirement:
It needs much smaller working space than other kinds of wind-power turbines. Thus not only saves the space, but also aises the working efficiency.
Power curve: It needs lower wind speed for its starting and the increasing of the power is slow and stable. So its production capacity is 10-30% higher than other kinds of turbines.
Scope of the wind power needed:
Due to the adoption of the new control system, this VAWT is suitable to be used in the wind speed scope from 2.0 25 m/s.. It means we can get full use of the wind source and producing more power economically.
