A method and system to capture kinetic energy of the sea waves and convert it to electrical power is presented. The hydrodynamic power of the waves is converted to mechanical power after impacting and moving a special panel. The mechanical power is converted into a controlled-cycle hydraulic power to activate a hydraulic motor, which in turn activates an electrical generator. Electrical power is then measured, controlled and distributed to a power grid or end users.
