Solar Desalination Systems
The provision of freshwater is becoming an increasingly important issue in many areas of the world. In arid areas, potable water is very scarce and the establishment of a human habitat in these areas strongly depends on how such water can be made available. A brief historical introduction to solar desalination is given in Chapter 1, Section 1.5.2.
