Working in conjunction with UC Berkeley and the Peace Corps, a San Francisco-based laboratory has produced a prototype atmospheric well that, powered by wind alone, can harvest litres of clean water. The Water Seer’s turbine push air into a buried condensation chamber (cache) to be collected as needed and is a completely closed system, requiring no extra plumbing or purification-process—very similar to the techniques that Frank Herbert described for the Fremen of the desert world of Arrakis.
