Title: Wind turbine

Abstract: A wind turbine having a wing rotor with two rotor blades supported on a hub; to accommodate different wind velocities nearer and further from the ground and to accommodate the components of wind force transverse to the rotor blade plane of rotation, the pitch of the blade that is then higher above the ground is altered with respect to the pitch of the blade that is nearer to the ground; this can be done by appropriate swivel mounting of the rotor hub for allowing its reorientation to change the effective pitch of the blades as they rotate high and low; or it can be done by a blade swiveling means sensitive to wind conditions.
