ABSTRACT OF THE DISCLOSURE: A windmill of the type having a rotor rotatable about a vertical axis, and a wind deflector rotatably mounted relative to the rotor about the same vertical axis to be able to position a wall between a portion of the rotor and the wind. This wall is advantageously shaped in a manner to create a reduced pressure behind it to make the rotor more efficient. A driving system is provided for automatically rotatably positioning the wind deflector to maximize the wind effect on the rotor. This system can be override for auto-rotatably positioning the deflector back in such a position as to reduce the wind effect on the rotor as the wind speed increases above a predetermined speed.
