ABSTRACT:
An improved fluid driven turbine blade system is provided, which is self-governing at relatively high fluid velocities. This is achieved by a combination of two sets of turbine blades, one having a positive efficiency, and the other having a negative efficiency at the fluid velocity at which the self-governing effect occurs. Also provided is a variable friction drive apparatus for powering an energy conversion device. The combination of the improved turbine blade system and the variable friction drive comprises a windmill for driving an electric generator, the windmill having a low required start-up torque at low wind speeds and being self-governing so as not to overspeed the generator at high speeds.
