TECHNOLOGY
ADVANTAGES:
  • The wind flow on the rotor will together with the rotor rotational speed create a lift on the blades (like on an airplane)
  • The lifting force on the blades integrates to a rotor rotational driving force.
  • The yaw drive holds the turbine in the wind.
  • The turbine uses an aerodynamic and secure mechanical brake.
