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

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

Apparatus for controlling the conversion of natural wind forces into useful energy comprising: a frame, shaft means rotatably mounted on said frame; first cross arm means connected to said shaft means having first impeller means disposed thereon to cause rotation of said first cross arm means and said shaft means means in response to wind; second cross arm means connected to said shaft means and disposed at an angle to said first cross arm means and having second impeller means disposed thereon to cause rotation of said second cross arm means and said shaft means in response to wind; adjustment means for moving said second cross arm means about said first axis relative to said first cross arm means to change selectively the angular position of said second cross arm means and second impeller means relative to said first cross arm means and first impeller means, whereby the speed of rotation of said shaft means may be controlled for varying wind conditions.
