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
