The Watercone makes salt and brackish water fresh using only the sun, evaporation, and a simple, portable plastic cone. Every day 5000 children die as a result of unsafe water-related diseases, and Watercone provides up to 1.6 liters a day, covering all of a child’s daily water needs. The process is simple- fill the black base pan with salty or brackish water, float the cone on top. The black pan absorbs sunlight and heats up the water to support evaporation. Through condensation, the evaporated water collects in the form of droplets on the inner wall of the cone. These droplets trickle down the inner wall into a circular trough at the inner base of the cone. The cone can then be flipped over and the fresh water poured out.
