Vertical Axis Wind Turbine Installation - Renewables NB

This vertical axis wind turbine is unique because it is equipped with diffusers, which create a vacuum effect and help to draw wind from all angles into the center of the turbine. This property allows the wind turbine to begin producing electricity at much lower wind speeds 5 km/h (3 mph) as opposed to standard windmills 13-16 km/h (8-10 mph ).
