ABSTRACT:
A windmill having a shroud rotatably mounted with respect to a horizontally rotatable vane assembly of the windmill and a directional vane mounted to the shroud to automatically position the shroud to expose half of the windmill vane assembly to the wind. The directional vane is adjustably mounted to the shroud so that the directional vane can be positioned with respect to the shroud to provide a range of positions of the shroud from a position in which the effect of the wind is at a maximum to a position at which it has no effect at all.
