This desalination method is comprised of recycled materials thereby reducing the amount of pollution in the world. This desalination method uses no other power sources other than solar energy. The usage of recycled materials and renewable energy sources thereby ensures that this desalination method is a low cost way of transporting seawater and converting it into fresh water.

Abstract: A solar still apparatus is described for the multi-effect distillation of a fluid such as water. A transparent condenser air duct overlies an evaporator air duct having a light-absorbing floor, both sharing a transparent plastic film wall. Air, blown by a fan, flows through the lower duct, where it progressively warms and evaporates a feedstock fluid.

Thermal gradients established within the still facilitate the evaporation and condensation of the fluid with minimal heat loss to the environment and maximal recuperation of the heat of condensation for fluid evaporation. A working fluid may be used to extract useful power from the still's thermal gradients.
