Abstract: The kinetic energy of the wind is converted into compressed air which is stored, in a system which maintains a predetermined output pressure, for use in driving a turbine coupled to an electrical power generator. The gas storage system includes two pair of serially connected storage tanks with the first tank in each pair receiving compressed air from wind driven compressors and including a hydraulically actuated piston for use in forcing the air into the second tank. Each of the second tanks of each pair includes a floating piston which will be caused to ascend in response to the delivery of pressurized gas thereto from the serially connected tank including the hydraulically actuated piston and the pressure in each of the second tanks will be maintained by the weight of the floating piston.
