Aeolian Wind Focus Effect
- Uses existing surface area of a pitched roof to collect and focus the prevailing wind
- Wind forced to travel over the roof surface
- Forms a pinch point at the roof ridge
- Air flow is accelerated through the turbine
- Measured wind speed around the ridge can be just over three times the actual wind speed
- Up to nine times the energy is available to it compared to a VAWT (Vertical Axis Wind Turbine) system

Unique Design,Unique Performance
- Consistent power generation even in turbulent wind conditions
- Uses advanced aerodynamics to prevent noise in operation
- Designed to self-limit the speed of the rotor
- Units achieve full capacity at wind speeds of only 25mph
- Self-regulating so rotor speed is not exceeded, even in severe storm conditions
- Low-profile, self-regulating and “planning-friendly” design
- Ideal for commercial and urban areas with turbulent winds
