Abstract:
By means of solar energy potable water is produced from seawater or
brackish well water in the process of desalination or distillation.
The solar still consists of a shallow pool of brine covered by sloping
panes of glass. The water is evaporated by absorbed solar radiation and the
vapour condenses on the underside of the glass covers, which are cooled at
the outside by convection. The water droplets trickle down the glass to be
collected in narrow drains along the bottom.
