ABSTRACT:
A wind responsive power generating apparatus (20) comprises a pair of normally mutually orthagonal cross arms (22,24) carrying impeller members (22a,22b, 24a,24b) that apply torque to a load (38) through an output shaft (26). The power output of the apparatus (20) is reduced from maximum by reducing the angle between adjacent cross arms and simultaneously rotating impeller members about corresponding cross arm axes to provide air spillthrough. The impellers are selectively vented by valves (46) to reduce drag as each impeller member swings upstream. Operation of the valves (46) is synchronized to impeller rotation and wind direction by a synchronization device (54). Various different types of impeller members and applications are disclosed. 00202
