Abstract

A wave pump apparatus includes a number of upstanding cylinders connected together by a subframe. Each cylinder mounts a float on the outside of the cylinder connected to a piston within the cylinder. The upstanding cylinders are spaced approximately a distance of half of an average wave length from the main floats of a particular wave pattern such that as certain floats are moving upwardly, other floats are moving downwardly. Each cylinder is connected to a chamber at the bottom thereof with an inlet valve and an outlet valve, such that as the piston in the cylinder is moving upwardly, it will draw in water, and as the piston moves downwardly in the cylinder, it will pump the water.
