Abstract

Drums floating on the sea slide vertically following the variations in sea level on account of waves or tides. Pistons of smaller surface area connected to them thus slide inside fixed cylinders connected to pressure chambers into which the sea water enters via suitable valves, developing high pressures. With suitable surface areas of drums and pistons, the pressures achieved produce desalinated water by reverse osmosis on passing through semipermeable membranes located in the chambers. The yield of desalinated water is proportional to the square of the tidal range or the waves. For 1m2 of drum surface area, it is possible to produce between 10 and 250 litres of water per day with tides and between 1 and 5m3 per day with waves. In general, desalination of sea water using wave and tide energy, through pressure amplification, is patented.
