MULTIPLE BLADE WIND TURBINE
A multiple blade wind turbine includes a base, a central support tower, and at least one rotor. The central support tower extends vertically from the base and is adapted to support the rotor. The rotor includes airfoil-shaped blades and an electric generator coupled to a set of closed loop tracks via a transmission. The set of closed loop tracks is spaced vertically apart from each other. The airfoil-shaped blades are interspaced within the set of closed loop tracks. Each airfoil-shaped blade is oriented perpendicular to the airflow and connected at each end to one of the set of closed loop tracks such that a windward and a leeward set of airfoil-shaped blades are aligned to form a linear cascade of parallel airfoil-shaped blades. Each airfoil-shaped blade has a pitch angle between 90 and 90 degrees and each airfoil-shaped blade is spaced between 1.0 and 2.5 chord lengths apart.
