Desalination of sea water - producing fresh water and salt from solar heat collectors, evaporators and wind power

摘要

A desalination system for the prodn. of drinking water and salt from sea water is based on solar and wind energy. Sea water is heated in covered shallow ponds during the hrs. of sunshine and is concnd. to produce fresh water by circulating through expansive evaporators during the remaining hrs. The power required for the circulation is gained from wind-driven generators. This saves fossil or nuclear energy and produces fresh water and salt from sea water and indigenous wind energy.
