ABSTRACT:
The double effect floating solar still uses a partly immersed corrugated metal plate to heat the upper layer of a body of water in order to establish a temperature difference between the upper and lower sections of the still. The difference in temperature creates a difference in vapor pressures, forcing the vapor produced in the hot section of the still to flow into a submerged condenser, giving up the heat of condensation to the surrounding water, preheating it before it reaches the stage of evaporation.
