There are a number of simple solar stills out in the world, but cost-effective, portable water desalinization equipment remains out of the reach of many in need. The Watercone is a low-tech device that uses the power of the sun to condense brackish or polluted water, then allow it to be collected for drinking.

Made of recyclable UV-resistant PET plastic, the Watercone has an average lifespan of five years. After its life as a water still, the Watercone can be used to collect rain water, as a roof panel or container for other goods.
