Abstract: There is described a rotor for a vertical axis wind turbine comprising: first and second blades connected to one another and arranged to rotate around an axis; wherein the first and second blades are disposed 180° apart with respect to one another and are offset from the axis in a radial direction; wherein an inner edge of each blade is spaced radially inwardly from an outer edge of the opposing blade to form a pair of diametrically opposed openings which open in opposite directions; wherein each of the first and second blades comprises a first curved section and a second oppositely curved section, the first and second curved sections being separated by a point of inflection; and wherein the first and second curved sections of the first and second blades overlap one another to form a passageway between the first and second blades which extends between the openings.

Abstract: A wind turbine system including a plurality of modules, each module including a frame and at least one wind turbine, a set of first electrically conductive members, and a set of second electrically conductive members. One of the first electrically conductive members is attached to a terminal of a generator and another of the first electrically conductive members is attached to another terminal of the generator to form a collection circuit configured to collect electricity generated by the turbine. The set of second electrically conductive members are connected to adjacent modules to form a concatenated string of second electrically conductive members to form a transmission circuit. The collected electricity is fed from the collection circuit to the transmission circuit along the concatenated string. At least one of the first electrically conductive members and at least one of the second electrically conductive members form structural rails of the frame.
