Solar Desalination Device

Active desalination systems usually require energy for cooling or compressing the water vapor and for the fans used to pump the water vapor through the system. Other desalination processes such as electrolysis or reverse-osmosis also require significant energy use so that the most efficient systems can only produce usable water at about three dollars per gallon. In order to support the larger requirements of agriculture and household use, energy efficiency must get to where water is cheaper than 0.50 US dollars per gallon.

This device is a solar desalination array for heating sea water into steam for the production of usable water and power generation. The heating columns normally operate in parallel and are heated by cylindrical mirrors which concentrate sunlight on each heating column. The heated sea water is either turned to steam and ejected out of the heating column or passed on to another heating column for further heating (and then ejection). When the water vapor is ejected from a column the system generates power, or pressure builds in the array and is used to power an external turbine with the steam. In either case, the use of the steam for power generation cools the vapor by decompression. Further compression or cooling can be done in a cooling tank or in a compressor powered by the turbine so that fresh drinkable water is produced.
