Using Ocean Movement To Power Desalination

Desalination is the process of taking seawater and processing it to make it drinkable for humans and animals. Although we have abundant seawater available to us, the desalination process is expensive in terms of building plants and using electricity to run them.

Since we are using ocean water, could we maybe use ocean tides and currents to power the desalination process? That's not my idea, but the concept behind a new process by SAROS Desalination, building on work done by the University of North Carolina at Charlotte.
The floating SAROS device (which is an acronym for Swell Actuated Reverse Osmosis System) isn't a wave energy device in the conventional sense - it doesn't generate electricity - but rather uses the energy of ocean waves to pressurize sea water and run it through a Reverse Osmosis process, and to then pump the fresh water to shore via a hose system. The device is said to be currently capable of producing about 500 gallons per day, and can produce up to 3,500 gallons of desalinated water per day at a slightly larger size, and to do so at a cost of about half of current desalination processes.
