Fog & Dew Collectors: Contraption For A Thirsty World


Here’s a potentially life-saving and thirst-quenching design prototype that we like: British designer Alon Alex Gross has created fog and dew collectors that build on conventional techniques of rain harvesting with lightweight, modern materials. Yet, the design is easy enough for people living in water-scarce developing areas to collect clean drinking water.

His dew collector, pictured above, weighs a mere 400 grams and has a special laminate foil that pulls dew drops to it, allowing it to collect up to 1.5 liters of fresh water per night. Because extreme conditions can harm the laminate foil, Gross has also designed an additional sensor system that can react to atmospheric changes by opening or closing the apparatus accordingly. Both are very refreshing and low-tech design responses, providing water to people who need it most.
