WIPO Patent Application WO/2012/075022
Kind Code:
A3
Abstract:
A windmill having a substantially vertical tower to which a rotatable hub is mounted. At least three arms extend substantially horizontally from the hub and terminate in cones having louvers that can be opened and closed, such as by a servo motor and linkage. A computer receives a signal from a wind direction sensor and actuates the opening and closing of the louvers to optimize wind resistance depending upon the orientation of the cone relative to the wind direction. Indicia are preferably placed on one or both sides of the louvers.
