Abstract
A wind turbine unit for generating electricity in a confined space includes a pair of sails carried at either end of a pair of spaced, axially aligned rotatable arms mounted to the drive shaft of an electrical generator. As the prevailing wind strikes the sails in opposite directions, one of the sails is moved to a vertical position while the other sail is moved to a horizontal position. The wind incident on the then vertical sail causes the arms to rotate about the longitudinal axis of the generator and the sails are alternatively raised and lowered between a vertical and a horizontal position so that one of the sails is vertical while the other is horizontal.
Claims9
A wind turbine comprising at least one arm, first and second wind-receiving members or sails mounted in a common plane at either end of said arm, said arm being mounted for rotation about the central longitudinal axis of an electric generator, and means responsive to the sensed direction of the prevailing for alternatively positioning one of said sails in a vertical orientation to receive the incident wind while causing the other of said sails to be positioned in a horizontal orientation.
