Building Integrated Solar Desalination (BIDSAL): Preliminary Works with Multiple Effect Solar Still

With relatively high productivity compare to single solar still, multiple effect solar still (MES) could be useful to supply water to remote place which can not afford enough budget to install huge scale desalination plant. Since MES has panel shape, it might be applicable as part of building surface material, enabling “building integrated desalination” (BIDSAL). Since cost of land and installation can be partially compensated by regular construction cost of buildings in BIDSAL, MES could be a practical solution for micro solar desalination, if it can be produced in low cost. Some preliminary work to make low cost MES was done as well as its outdoor test.
