ABSTRACT:
The wind rotor of the present invention includes a vertically disposed, rotatable shaft operatively connected to a conventional generator. A plurality of bent lever arms are uniformly radially attached to the shaft and extend outwardly therefrom. Each arm has a vertically disposed rectilinear airfoil blade connected to the outer end thereof such that the wind generates aerodynamic lifting forces on the blades to cause rotation of the wind rotor. The bent lever arm transmits a greater portion of the lifting forces to the central shaft for increased torque in the wind rotor.
