Patent ID: 7230348

Claim:
A wind turbine for generating electrical power, comprising: a vertical “Savonius rotor type” wind rotatable turbine having multiple fixed pitch blades; a rotatable wind inlet duct having an identical number of multiple infuser-shaped aerodynamic guides as said pitch blades and mounted in the duct to direct equal air flow at higher speed to load each of said multiple fixed pitch blades and forming an infuser system; said wind-rotatable turbine being mounted within said inlet duct and infuser system; a synchronous generator driven by said vertical turbine; an electrically driven hold-down spring system enabling said wind turbine to disconnect from said generator when the wind speed is above maximum safe operating speeds; an automatic control system that controls electrical power to said electrically driven hold-down spring system enabling the wind turbine shaft to be automatically loaded or unloaded to the generator shaft based on the incoming wind speed measurement; and a wind speed measuring system mounted to the rotating duct system and connected to said automatic control system.
