A plant for producing electrical power from the movement of waves. An offshore dam has a fixed generally vertical surface which is located in open water having wave movement and located vertically at the water surface. A submerged part which is fixed relative to the dam has an opening below the waves and in close proximity to the plane of the vertical surface to receive sea water. A force exerting structure such as a hydraulic pump or a thrust arrangement receives the water through the opening and forces that water through a one-way valve beyond which it is led to a turbine for producing electric power.

1. A plant for producing electrical power from the movement of waves, comprising: an offshore dam having a fixed generally vertical surface located in open water having wave movement and located vertically at the surface of the water where the waves would lap against it,a submerged part formed in and thus being an integral part of the dam and having an opening below the waves and in close proximity to the plane of the vertical surface for receiving the sea water and a one-way valve allowing the water entering the opening to pass through it,a force exerting structure also formed in and thus being an integral part of the dam for receiving the water entering the opening and forcing that water through the one-way valve, anda turbine in communication with the one-way valve for receiving the water which passes therethrough. 2. A plant according to claim 1, wherein the turbine is fixedly mounted with respect to the dam. 3. A plant according to claim 2, including a tank fixedly mounted relative to the dam, which tank has an inlet connected to the one-way valve to receive and store water passing through the one-way valve, the tank having an outlet in communication with the turbine for delivering water thereto. 4. A plant according to claim 3, wherein the outlet is positioned to deliver water downwardly by gravity to the turbine. 5. A plant according to claim 2, including a fluid line connected to an outlet of the turbine to recirculate the water. 6. A plant according to claim 1, wherein the turbine is located in a land zone at a distance from the dam. 7. A plant according to claim 1, wherein the force exerting structure comprises a hydraulic pump having a vertical cylinder, a piston mounted to reciprocate vertically in the cylinder and a float connected to the piston and movable vertically to follow the oscillations of the movement of the waves, the cylinder being in communication with the one one-way valve to force water out of the cylinder and through the one-way valve, upon such vertical movement of the piston. 8. A plant according to claim 7, said cylinder having near each end thereof on opposite sides of the piston a said one-way valve in communication with the turbine and a further one-way valve which comprises said opening for receiving sea water, whereby movement of the cylinder in each direction pushes water ahead of it through the said one-way valve to the turbine while permitting sea water to enter the cylinder behind the piston through a further one-way valve. 9. A plant according to claim 7, wherein said dam has fixed thereto a tubular seat in which said float is slidable vertically. 10. A plant according to claim 9, wherein the tubular seat is cylindrical. 11. A plant according to claim 10, wherein the float comprises an upper section and a lower section, each having a substantially conical or frustroconical shape so as to facilitate the rising and descending movement of the float. 12. A plant according to claim 10, including an expansion chamber entering the tubular seat above the said cylinder and below the float. 13. A plant according to claim 1, wherein said submerged part comprises a chamber with said opening in the form of a large inlet for receiving sea water, and said force exerting structure comprises an upwardly slanted bottom wall of the chamber and a vertical wall across from the inlet, the one-way valve being located at an upper part of the chamber, and the cross section of the chamber narrowing from said inlet toward said one-way valve. 14. A plant according to claim 1, including a floating platform anchored to the sea bottom, and said dam being supported on the platform. 15. A plant according to claim 14, including struts hinged to the platform to anchor the platform to the sea bottom. 16. A plant according to claim 15, wherein the struts are anchored to legs or sinkers on the sea bottom. 17. A plant according to claim 1, wherein the plant is made from prefabricated elements of sheet metal or concrete to be secured to existing dams. 18. A plant for producing electrical power from the movement of waves, comprising: an offshore dam having a fixed generally vertical surface located in open water having wave movement and located vertically at the surface of the water where the waves would lap against it,a submerged part fixed relative to the dam and having an opening below the waves and in close proximity to the plane of the vertical surface for receiving the sea water and a one-way valve allowing the water entering the opening to pass through it,a force exerting structure for receiving the water entering the opening and forcing that water through the one-way valve,a turbine in communication with the one-way valve for receiving the water which passes therethrough, andwherein said submerged part comprises a chamber with said opening in the form of a large inlet for receiving sea water, and said force exerting structure comprises an upwardly slanted bottom wall of the chamber and a vertical wall across from the inlet, the one-way valve being located at an upper part of the chamber, and the cross section of the chamber narrowing from said inlet toward said one-way valve. 19. A plant for producing electrical power from the movement of waves, comprising: an offshore dam having a fixed generally vertical surface located in open water having wave movement and located vertically at the surface of the water where the waves would lap against it,a submerged part fixed relative to the dam and having an opening below the waves and in close proximity to the plane of the vertical surface for receiving the sea water and a one-way valve allowing the water entering the opening to pass through it,a force exerting structure for receiving the water entering the opening and forcing that water through the one-way valve,a turbine in communication with the one-way valve for receiving the water which passes therethrough, andincluding a floating platform anchored to the sea bottom, and said dam being supported on the platform. 20. A plant according to claim 19, including struts hinged to the platform to anchor the platform to the sea bottom. 21. A plant according to claim 20, wherein the struts are anchored to legs or sinkers on the sea bottom.
