Editing Desalination (section)

====Solar distillation====
[[Solar distillation]] mimics the natural water cycle, in which the sun heats sea water enough for evaporation to occur.<ref name=Khawaji /> After evaporation, the water vapor is condensed onto a cool surface.<ref name=Khawaji /> There are two types of solar desalination. The first type uses photovoltaic cells to convert solar energy to electrical energy to power desalination. The second type converts solar energy to heat, and is known as solar thermal powered desalination.
