A system for the conversion of sea wave energy including a breakwater structure including a wave energy collector integrally formed within the breakwater structure. The energy collector collects and directs oncoming waves to an upwardly extending duct having hydraulic oil separated from seawater by a membrane for converting the wave energy into oil pressure. The wave energy collector incorporates a plurality of control valves which are electronically coupled through a computerized control system which regulate the control valves so that the optimum wave pressure is collected and transferred to the hydraulic oil. A piping system conducts the pressurized hydraulic oil to a pressure tank which is connected to a hydraulic motor which is mechanically coupled to an electric generator. The system may be combined with a solar distillation apparatus.
