An ocean wave powered desalination system

An ocean wave-driven sea water desalination plant for generating both fresh water and electrical power from sea water, the desalination plant comprising:

• at least one hinged flap for oscillation by wave surge force, the at least one hinged flap driving at least one pump which receives filtered sea water and generates pressurized filtered sea water, and the at least one pump supplying the pressurized filtered sea water to both a house power electric plant and a freshwater generation plant;
• the house power electric plant including a hydraulic motor for receiving a first portion the pressurized filtered sea water from the at least one pump and generating electrical power therefrom;
• and
• the freshwater generation plant receiving a second portion of the pressurized filtered sea water from the at least one pump and generating fresh water therefrom;
• wherein a speed of the hydraulic motor is varied so as to vary the flow of the first portion of the pressurized filtered sea water through the hydraulic motor and thereby maintain a substantially constant pressure of the first and second portions of the pressurized filtered sea water so that the second portion is supplied to the freshwater generation system at a substantially constant pressure so as to facilitate substantially continuous generation of fresh water during operation of the desalination plant at optimum RO feed water pressure.
