The weight of water limits how much can be brought on a long bike ride. There isn’t always an option to stop and fill up from a clean stream or drinking fountain, but water could be obtained from a different source: the air. Austrian industrial design student Kristof Retezár has created Fontus: a prototype of a water bottle system that condenses humid air into clean, drinkable water. His design made him a finalist for the 2014 James Dyson Award.
The Fontus attaches to the bicycle frame and consists of a condenser unit and a bottle for collection. There is a solar panel on top of the unit that powers the condenser. As the motion of the bike causes air to blow into a channel, the moist air is cooled, causing it to condense. The droplets roll back down the condensing unit, collecting in a water bottle mounted underneath.
