The document proposes a solution to purify salt water for consumption in poor, rural areas by using a simple distillation process. It involves heating salt water in a metal cup placed above a cardboard box lined with aluminum foil and containing a concave cardstock reflector. The rising water vapor would pass through a plastic tube into an empty bottle, where it would condense into fresh water for drinking. Research showed salt water contains 3.5% salt on average and distillation is an effective purification method using common, reusable materials. Key steps and materials for the design are outlined.
