  • Ocean raft energy generator
    Patent number: 4379388
    Abstract: A system for generating electricity contained within an ocean raft. The raft has a series of raceways for heavy metal balls, and, as they roll back and forth, they engage levers which reciprocate back-to-back paired pistons in opposite directions. Each pressurizing movement of a piston discharges a jet of fluid to a common pressure tank from which the pressurized fluid drives a turbine.
