Abstract: A wave operated power plant is provided wherein a buoyant vessel is anchored on the ocean surface with the wave motion causing displacement of water carried in a chamber in the hull such that upon rocking motion the water is forced upwardly through pipes on one side of the vessel. The water contacts turbine blades which through shafts rotate electrical generators and generate electricity. The water is returned to the chamber when the vessel moves in the opposite direction and the cycle is repeated with water forced up through pipes in the other side of the vessel, used for electrical generation and then returned to the chamber. The water being forced up from the chamber can contact the blades directly or be stored in a tank on top of the vessel and released at a predetermined rate.
