Abstract

A wave energy conversion system in a body of water with land, including a stationary element, which is secured to bottom of a body of water; Buoyancy means including buoy portion and wave energy collector shaped as passive cavity mounted on the buoy. The cavity includes an opening, which is oriented at general direction of the oncoming waves. Coupling to connect the buoy to the stationary element, so that the buoy lies in a vertical plain by a central axis in the alleged stationary element; At least one piston for the pressing and pumping of hydraulic fluid, when the piston expands and retracts, respectively. The piston is connected to one end of stationary element or to the floor, and at the other end to the buoy or coupling; Hydraulic motor connected to electrical generator or a similar device; Piping system, which combines hydraulic fluid in the piston to hydraulic motor.
