  • Vertical axis wind turbine with self-orientating blades
    Patent number: 10378510
    Abstract: The invention is a wind turbine that is part of a system for utilizing the energy of wind to produce electrical energy. The turbine is a vertical axis wind turbine that is characterized by the design of its blades. The blades are shaped and attached to the turbine in a way that allows them to self-adjust their orientation with respect to the direction in which the wind is blowing. In this way the torque that each blade exerts on the turbine consist of two portions. When the blade is on the windward side of the turbine, it exerts on the turbine torque from the drag force. When the blade is on the leeward side of the turbine, the torque that the blade exerts on the turbine is from lift force.
