On a small scale solar thermal  can  provide  much  lower cost  drinking water from seawater than  other methods.   According to Nottingham University experiments  up to 20 kilos of water per day per  square metre collector area.  Heat is used to evaporate  seawater and seawater also cools the  condenser.  Pumps can be PV driven.    The system needs to  have mass produced  evaporator/condenser units to become fully viable and unfortunately most of the areas that need these systems have  low incomes.
