ABSTRACT:
A wind turbine has a horizontal axis of rotation and features a hub beam and two turbine blades attached to opposing ends of the hub beam in a spaced-apart relation. The blades have a first position in which the blades are radially arrayed about the hub beam. The blades have a second position in which the blades are folded and moored to the tower. A control system communicates with weather sensors and determines whether to move the blades between the first and second positions.
