Autonomous Wave Powered Desalination
First Claim
1. A desalinating device, comprising:
- a compression chamber having an interior and being configured to receive water,the compression chamber having an inlet, a proximal end, a distal end, and a major axis extending longitudinally from the proximal end to the distal end;
an inlet one-way valve sealably engaged with the inlet,the inlet one-way valve being configured to permit flow into the compression chamber from exterior to the compression chamber;
a piston operatively coupled to a wing,the piston being sealably disposed within the compression chamber, and,the piston being configured to move along the major axis of the compression chamber in the direction of the distal end of the chamber in response to the movement of the wing;
a reverse osmosis membrane being in fluid communication with the interior of the compression chamber such that motion of the piston in the direction of the distal end of the compression chamber exerts contents of the interior of the compression chamber against the reverse osmosis membrane; and
a spring member in fluid communication with the interior of the compression chamber,the spring member being configured to compress when the piston moves in the direction of the distal end of the compression chamber.

Abstract
A wave powered water desalinating device may receive untreated salt water, and produce desalinated fresh water. The device consists of a pressure chamber, with a piston coupled with a pitching-type wave energy converter and configured to move along the major axis of the compression chamber; an inlet one-way valve configured to permit flow into the compression chamber from the exterior; a spring in fluid communication with the piston configured to absorb and control the cyclic pressure of the system; and a reverse osmosis membrane in the interior of the compression chamber such that motion of the piston in the direction of the distal end of the chamber exerts contents of the interior of the chamber against the reverse osmosis membrane producing fresh water.
