Closed loop multiple airfoil wind turbine

A multiple blade wind turbine comprising:

• at least one rotor comprising a set of closed loop tracks arranged in a single plane with respect to an airflow direction;
• a plurality of airfoils interspaced within the set of closed loop tracks, wherein the set of closed loop tracks is oval,
• wherein each of the plurality of airfoils have a leading edge, a trailing edge, a pressure side, a suction side, a chord length, and a span length;
• wherein each of the plurality of airfoils is connected at each end to one of the set of closed loop tracks, where the leading edge and trailing edge are parallel to the single plane, and each of the plurality of airfoils are fully rotatable with respect to the single plane;
• wherein the plane of the set of closed loop tracks is perpendicular to the airflow;
• wherein each of the plurality of airfoils have a pitch angle between 15 and 90 degrees;
• wherein each of the plurality of airfoils are spaced between 0.3 and 6.0 chord lengths apart;
• a central support tower, wherein the central support tower is coupled to the at least one rotor;
• a transmission mechanically coupled to the set of closed loop tracks, wherein the set of closed loop tracks drives the transmission;
• an electric generator connected to the transmission;
• and
• a generator housing that contains the electric generator and the transmission.
