Solar Stills  Solar still is a device to desalinate impure water
like brackish or saline water. It a simple device to get
potable/fresh distilled water from impure water, using solar
energy as fuel, for its various applications in domestic,
industrial and academic sectors.  Solar Still Water  A solar
still consist of shallow triangular basin made up of Fiber
Reinforced Plastic (FRP). Bottom of the basin is painted black 
so as  to absorb solar heat effectively. Top of the basin is 
covered with transparent glass tilt fitted so that maximum solar
radiation can be transmitted in to the still. Ages of the glass
are sealed with the basin using tar tape so that the entire
basin becomes air tight. Entire assembly is placed on a
structure  made of MS angle. Out let is connected with  a 
storage container.  Provision  has been made to fill water  in 
the  still basin.  A window is provided in the basin to clean
the basin  from inside. Water is charged in to the basin in a
thin layer.  Solar Stills have got major adva
