Abstract: A solar tracking device for overcoming the disadvantages of a conventional solar energy system utilizing motors and to lower electricity consumption and decrease cost is provided. The device includes a solar module or solar collector supported by two springs under both ends and two water tanks on both ends. The solar module or solar collector, similar to a heliostat, is adapted to slowly revolve in response to the imbalanced water tanks filled with different amount of water.

Abstract: A method and apparatus includes supplying fresh water and generating electricity from collected rainwater. The method includes providing hollow buoyant members under the reservoir as support. The method also includes providing steel ropes, driving piles into the ground and securing the piles to the steel ropes. The method also includes forming gates, building hydroelectric generators, building a waterworks, and providing tubes connected from the gates to the waterworks through the hydroelectric generators. Rainwater collected and stored in the reservoir is transferred to the hydroelectric generators. Further, the waterworks is adapted to receive water from the hydroelectric generators. Moreover, sprinklers, drive devices, and oblique plates for directing rainwater and decreasing evaporation may be provided.

Abstract: A solar tracking device is disclosed. In particular, a solar tracking device for overcoming the disadvantages of conventional solar energy system utilizing motors and to lower electricity consumption and decrease cost is provided. The device includes a solar module or solar collector supported by two springs under both ends, and two water tanks on both ends, wherein the solar module or solar collector, similar to a heliostat, is adapted to slowly revolve in response to the imbalanced water tanks filled with different amount of water.

Abstract: An ocean wave energy conversion apparatus includes a float adapted to ride on the surface of the ocean in reciprocal vertical motion in response to ocean wave front action and a lever adapted to ride on the surface of the ocean. The lever has one end coupled to the float. A fulcrum pivotally supports the lever. A magnet is coupled to the other end of the lever. Parallel stator cores having electric coils wound thereon together with the magnet form a magnetic circuit. Springs are adjacent the magnet and interconnected to the lever and the magnet. A barrier is disposed between adjacent stator cores. The upward motion of the float caused by impact of waves will move the magnet downward by the lever and compresses the springs. Downward motion of the float will move the magnet upward by the lever and expand the springs. Repeated movement of the magnet will induce a voltage in the electric coils.
