The Watercone® is a solar water still, making distilled water from salty/brackish water, yielding 1 to 1.4 liters of water per day. The design is a conical self-supporting, stackable unit made from transparent, thermo-formable polycarbonate material outfitted with a screw cap spout at the tip and inward circular colleting trough at the base. Based on the evaporation rate of 8.8 liters per square meter, the salty/brackish water evaporates and forms droplets on the cone's inner wall. To empty the distilled water, unscrew the cap at the tip of the cone and turn the cone upside down. This simple, utilitarian solution will improve the lives of the world's population and is a powerful example of back to basics problem solving.

"The Watercone® is a highly innovative solution to one of the most basic needs in developing countries. The design developed by Augustin is one of the most compelling examples of design I have seen. The focus on performance has created a design that is uniquely relevant to the need. It's beautifully simple, functional and intuitive. The Watercone® demonstrates how design can play a key role in improving the lives of many around the world." -Duncan Paul, I/IDSA, Global Design Leader of Fabric and Homecare, Procter and Gamble Eurocor NV.
