ABSTRACT:
A system is disclosed for generating electric power in response to the rise and fall of tidal water. The system comprises a movable container which is mounted on a float to move up with the tide with reference to a coaxially enclosed fixed plunger, which comprises and forces a body of liquid in the movable container to overflow into a first trough adjacent its upper end. The movable container is rigidly coupled to a movable plunger which depends coaxially into a fixed container, the plunger moving down with the tide to compress a body of liquid in the fixed container, causing it to overflow into a second trough adjacent its upper end. The two troughs are interconnected vertically through a gravity flow system, including a turbine which is constantly operated by the liquid falling from one or the other of the troughs, as the tide rises and falls. One embodiment comprises two fixed containers with movable plungers and two movable containers with fixed plungers. In another embodiment, a fixed container coaxially encloses a fixed plunger, between which is coaxially disposed a third body which serves in the dual capacity of a movable plunger to the fixed container, and a movable container to the fixed plunger.
