This is almost magic: A water bottle that keeps filling itself as it condenses the air. The fear of dehydration during a long hike is gone. The Fontus water bottle is designed to capture the moisture contented in the air, condense it and store it as safe drinking water. A small fan draws the air from the surrounding environment, runs it through a special filter and presses it into the condensation chambers. Great for outdoor enthusiasts but also a promising technology for the many places in the world where clean drinking water is scarce.
