Abstract: An electrical energy generating system that does not cause destruction of natural environment and environment pollution in installation of the generating device and in the operation thereof is provided. The electrical energy generating system comprises a water electrolyzer using a wind power generator as the power source, a hydrogen combustion furnace including a water tank connected to the water electrolyzer, and a generator having a turbine connected to the hydrogen combustion furnace; wherein hydrogen and oxygen electrolyzed by the water electrolyzer are fed to the hydrogen combustion furnace, the hydrogen is combusted in the hydrogen combustion furnace, water in the water tank of the hydrogen combustion furnace is heated by the heat generated by combusting hydrogen to generate water vapor, the water vapor is supplied to the generator, a rotary vane of the turbine is rotated and power is generated in the generator.

Abstract: In a wind power generating system, a pair of axially spaced turbines are connected to an outer rotor and an inner rotor of a generator, respectively, and are provided with blades having equal but opposite pitch angles so that the inner and outer rotor rotate at a same rotational speed in opposite directions. Because the relative rotational speed between the inner and outer rotors is twice as great as the rotational speed of the inner rotor or outer rotor, the generator system can produce a relatively large electric power even when the wind speed is low. If desired, a pitch varying mechanism for the turbine blades may be done away with so as to reduce the manufacturing and maintenance costs.
