This novel wave energy technology can deliver large volumes of high pressure water ashore for desalination or power production (or both).

By combining solar PV, solar thermal, and a heat exchanger, Desolenator has developed a low-cost portable water purifier and desalination device powered by renewable energy.

This system could produce 3,500 gallons of clean water per day, at half the cost of current desalination methods, using just the motion of the waves to power the Reverse Osmosis process.
