<p>Disclosed are various embodiments of cross wind turbines (100) that are capable of providing high efficiencies over a wide range of wind velocities. An airfoil stator (102) causes wind to accelerate along its surface and creates a low pressure area on the leading face of the rotor blade (110) during the power stroke. A blocking stator blocks wind from impeding the movement of the rotor blades during the return cycle and directs wind onto the trailing face (122) of the rotor blades (110, 112) during the power cycle. A large pressure differential is created between the leading face (120) of the rotor blade (110) and the trailing face (122) of the rotor blade (110) during the power cycle which creates a large amount of force that rotates the rotor blade (112) about the central shaft (114). In some embodiments, gaps (208) are provided between the inside edge of the rotor blade (206) and a stationary shaft (202) which vents wind collected by the rotor blade (204) during certain portions of the rotation cycle. The vented wind increases the pressure on the trailing face (212) of the rotor blades (204) during the return cycle to further assist in the efficiency of this system.</p>
