DEVICE FOR GENERATING ELECTRICITY BY HYDROSTATIC PRESSURE OF SEA* LAKE OR RIVER

摘要

A large container is placed at the bottom of a reservoir. It has an inlet controlled by a valve through which water flows from the reservoir into the container. This flow drives a turbine just inside the container. A pump takes water out of the container through a suction pipe and returns it to the reservoir outside the container. The pump can be driven by off peak electricity while the valve is shut so that the container is emptied for generation to take place by gravity flow during the peak period. Alternatively the pump can be driven by a wind impeller while the turbine is running.
