ABSTRACT:
A fluid driven turbine includes a central rotor having a plurality of wind blades mounted circumferentially around the axis of the rotor and arranged to define a general spiral configuration extending along the axis of the rotor in a predominant fluid flow direction. The hub is spherically shaped to force the fluid outward with an increase in velocity into engagement with the blades.
