Designed to use the existing roof area of a pitched roof to collect and focus the prevailing wind using the Aeolian wind focus effect. This is where the wind is forced to travel over the roof surface and forms a pinch point at the roof ridge, accelerating the airflow though the turbine. As a result, measured wind speed around the ridge can be just over three times the actual wind speed. Placing th
e turbine in this high flow area means that up to nine times the energy is available to it compared to a HAWT (Horizontal Axis Wind Turbine) system. The RidgeBlade uses advanced aerodynamics to prevent noise in operation, and is also designed to self-limit the speed of the rotor through its unique patented aerodynamic properties. This means that the units achieve full capacity at wind speeds of only 25mph and at this level of wind, the turbine speed achieves its maximum rotational speed, and this rotor speed is not exceeded, even in severe storm conditions. The Ridgeblade product is currently owned and sold by the Power Collective company in Canada.
