The rain, wind, wave, and solar energy 4-in-1 electric generating installation comprises mainly a wind wheel (2), a water wheel (3) two solar plates (1 and 1A), a wind and current plate (4), a turntable (6), and four floats (14). All these components work in combination to convert 4 natural resources, namely rain, wind, waves, and sunlight into useful electricity with automatic adjustment to the level of tide, and direction of wind and current. The installation can be used either in water or, with some minor modifications, on land. By means of this installation, even without 1, 2, or 3 of the 4 natural resources, generation of electricity will not be suspended. The invention, therefore, has great advantages over the conventional electric generators.

A wind power generation system mainly includes a wind catching mechanism slidably mounted on a guide rail mechanism. The wind catching mechanism includes a wind-catching means that is selectively oriented to face wind blowing against it, so as to cause the entire wind catching mechanism to slides along the guide rail mechanism before the wind and pulls a linking cable connected to a dynamo, so that the dynamo is actuated to generate power.

A wind-generated power system for producing supplemental electrical power from wind-producing resource. The wind-generated power system includes a subway system tunnel having a wall and support structure with wind being generated by subway trains passing or traveling at high rates of speed therethrough; and also includes wind-collecting ducts being spaced throughout the subway system tunnel and being attached to the wall and support structure; and further includes shrouds being mounted to the wall and support structure and being connected to the wind-collecting ducts; and also includes turbine generators being mounted in the shrouds and being adapted to transform wind to electrical power.

An apparatus is provided for generating power, including modules connected in a closed loop. At least one module includes a duct. A motive fluid passes through the duct from the upstream side to the downstream side. An inlet fan is mounted in the duct at the upstream side for rotation about an axis. A motor or engine drives the inlet fan. A reaction turbine wheel is mounted in the duct downstream of the inlet fan on a rear shaft. The reaction turbine wheel has a plurality of pressure chambers disposed about the periphery of the reaction turbine wheel. The reaction turbine wheel is rotatable about the axis in a first direction, and the pressure chambers are curved from an upstream portion to a downstream portion in a second direction, opposite the first direction. An exhaust stator is mounted to the duct downstream of the reaction turbine wheel. An aft fan is mounted to the duct for rotation about the axis and is operably engaged to a rear axle. The rear axle is also attached to the reaction turbine wheel such that the aft fan rotates at a fixed speed with respect to the reaction turbine wheel. A power means is operably engaged to the reaction turbine wheel such that rotation of the reaction turbine wheel results in the generation of power.

A self-propelled wind power regenerator powered by the natural wind, by a propeller or a combination of both, depending on the condition of the wind and the demand of the electricity. During the period when the natural wind flows constantly above the cut-in wind speed, the wind turbine may be powered by the natural wind. When the useable natural wind becomes unavailable, the propeller is activated by a sensor that detects the drop of the output of the wind turbines. The propeller thus keeps the wind turbines running at the level of rated wind speed, and maintains the quality of the wind power regardless of the natural wind condition.
