Claim:
Production of electric power from the vertical motions of the sea mass characterized by a device based on shore in a natural, artificial pier or a breakwater, the device consisting of a metal or plastic cylindrical float ( 1 / 1 ) kept afloat half emerged, protected from side pressures and horizontal movements of the sea water inside a metal frame consisting of four vertical metal railway rails firmly fixed on the walls of the recess of the pier, this float being free to move vertically, sliding up-down following the motions of the sea surface, the motions of the float being transferred to a mechanism that converts the vertical motions to rotational ones, this mechanism consisting of two sections, the metal rectangular triangle ( 1 / 3 ) with its 90° corner founded in the edge of the pier inside the recess ( 1 / 4 ) shifts up-down, the other corner towards the sea being connected with the upper end of the intermediate vertical metal beam of the float ( 1 / 19 ), and the third corner of the triangle is connected to an additional metal arm ( 15 ) that acts as an intermediate between the metal triangle and the metal construction, having the shape of a reverse saw which in the place of the metal blade has two chains ( 3 / 20 ), these chains transferring the vertical motions of the float to two one-way gears ( 3 / 20 ) fixed side-by-side, one next to the other, in a common shaft ( 3 / 8 ), these gears rotating dynamically towards one direction and freely towards the opposite direction, the upper perimeter of gear A ( 3 / 20 ) embracing one chain and the bottom perimeter of the gear B embracing the other chain in such a way that in every motion of the sea surface, up or down and of any length, the shaft rotates on the same direction and activates the electrical generator.
