A wind turbine including a frame, a driveshaft rotatably mounted on the frame, and a body adapted to be driven by a wind. The body includes one or more spiral vanes attached to the driveshaft. The vanes may be assembled from a number of vane layers. The axis of rotation of the wind turbine is intended to be normally vertical, but it could be operated at other angles, including horizontal.
