Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A yaw control device for a wind turbine, comprising:
 a vertical wing having a leading edge and a trailing edge, wherein the vertical wing is configured to receive a vertical shaft, wherein the vertical shaft is biased toward the leading edge of the vertical wing, wherein the vertical wing rotates about a longitudinal axis of the vertical shaft.   
     
     
         2 . The yaw control device of  claim 1 , wherein at least a portion of the trailing edge is configured to accept a plurality of rotor blades disposed toward the trailing edge of the vertical wing. 
     
     
         3 . The yaw control device of  claim 1 , wherein the vertical wing is configured such that the leading edge faces in the direction of an approaching wind. 
     
     
         4 . The yaw control device of  claim 1 , wherein the vertical wing has symmetrical vertical surfaces.
