Solar stills

The use of solar energy in thermal desalination processes is one of the most promising applications of the renewable energies. Solar desalination can either be direct; use solar energy to produce distillate directly in the solar collector, or indirect; combining conventional desalination techniques,

A novel continuous single-stage solar still that makes use of a phase change energy storage mixture (PCESM) for promoting energy usage has been devised and constructed. The still consists of a module made from an external body of galvanized iron, a frame of galvanized iron, a pan at the bottom of th

A solar still in which charcoal functions both as heat absorber medium and as wick has been constructed. The still presents a 15% improvement in productivity over wick-type stills, is cheap, simple to construct, and in addition has the advantages of low thermal capacity, lightweight and ease of oper
