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 method of collecting water and generating electricity by a reservoir in the air or on the water is disclosed. The method includes the steps of providing hollow buoyant members under the reservoir as support; providing steel ropes; driving piles into the ground and securing same to the steel ropes; forming gate; building hydroelectric generators; building a waterworks; and providing tubes connected from the gates to the waterworks through the hydroelectric generators. Rain 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 rain and decreasing evaporation may be provided.
