A vertical axis sail-type wind turbine includes an array of sail-like structures that are mounted on rotating main masts. The sail-like structures can be oriented to interact with the wind. For example, when the sail-like structures are moving in a downwind direction, they are oriented to present a flat surface that is perpendicular to the wind direction. On the other hand, when the sail-like structures are moving in an upwind direction, they are oriented to present a surface that is at an angle that creates an upwind vector. The sail-like structures rotate about the sail masts, which are rotatably mounted to sail mounting arms that are firmly mounted to a main mast. The main mast rotates, transferring power through a gear and shaft drive to hydraulic pumps in the tower. This hydraulic fluid pressure is then used to drive an electrical generator.
