Abstract
A self priming gravity wave water pump, double acting, vertically self adjusting incorporating a submerged column platform as shown in FIG. 4A, the submerged column platform (22) can be tethered (28) or secured by a pivot to a weight (29) or fixed into the water bed (31). The column (22) can be incorporated into an additional submerged water filled column chamber (23), to operate as a hydraulic tidal adjustable column platform. The gravity wave pump (9) is a wave energy converter using wave energy in the form of wave motion to displace a float (2), to lift the pumps reciprocating piston (12) and uses gravity, causing a weight (3) to push a piston down as the wave passes. The pump could pressurise piped water to a head of up to 100 meters or more and could pump pressures in excess of 150 pounds per square inch when adjusted accordingly.
