Abstract:
1. A sea electricity energy production unit for passing a flow of water through a turbine to drive an electric generator, comprising: an intake section in fluid communication with a body of water and with a turbine inlet section for passing a flow of water from the body of water to said turbine inlet section; said turbine inlet section for receiving said flow of water from said intake section; a turbine connected to said inlet section for receiving said flow of water therefrom, and configured for discharging said flow of water to a discharge chamber, wherein said flow of water passing through said turbine powers said turbine to drive an electric generator; said electric generator connected to said turbine for generating electricity in response to being driven by said turbine; said discharge, chamber configured for receiving said flow of water from said turbine and passing said flow of water to a pressure reservoir; a first one-way valve disposed between said discharge chamber and said pressure reservoir for preventing a first flow from said pressure reservoir to said discharge chamber and passing said flow of water from said discharge chamber to said pressure reservoir; said pressure reservoir connecting between said discharge chamber and a discharge section for passing said flow of water from said discharge chamber to said discharge section; a second one-way valve disposed between said pressure reservoir and said discharge section for preventing a second flow from said discharge section to said pressure reservoir and passing said flow of water from said pressure reservoir to said discharge section; a hydraulic pump having a first section and a second section, said first section having a first piston moveable within said first section and said second section having a second piston moveable within said second section, said hydraulic pump having a hydraulic working fluid therein such that said second piston is moveable in response to movement of said first piston; a float disposed at a surface of a body of water and subject to waves occurring at said surface, said float moving upwards and downwards with the waves; a connecting rod connected on one end to said float and connected on another end to said first piston, such that upward movement of said float urges said second piston to move in a first direction, and downward movement of said float urges said second piston to move in a second direction; and wherein said hydraulic pump is connected to said pressure reservoir, such that said second piston is moveable in one of said first direction and said second direction to apply pressure to said pressure reservoir and push said flow of water through said second one-way valve and from said pressure reservoir, and said second piston is movable in the other of said first and second directions to draw down pressure on said pressure reservoir and pull said flow of water through said intake section, said turbine, said discharge chamber, through said first one-way valve and into said pressure reservoir.
