Abstract: A desalination system is provided that may be operated in a self-sustained fashion. The desalination system is comprised of (i) a wind turbine; (ii) an air compressor coupled to, and powered by, the wind turbine; (iii) a compressed air storage tank for storing the pressurized air from the air compressor; (iv) a pneumatic actuator that is powered by compressed air stored in the air storage tank; (v) at least one compression cylinder coupled to, and powered by, the pneumatic actuator; (vi) a source of salt water that is introduced into the compression chamber(s) of the compression cylinder(s); and (vii) a reverse osmosis desalination column that is configured to receive pressurized salt water from the compression cylinder(s) and output desalinated water.
