This self-filling water bottle was built for your bike. The solar-powered invention takes moisture in the air and turns it into drinkable water. Designed by Kristof Retezar, Fontus can collect up to half a liter of water in one hour in ideal climate conditions, or a constant flow of one drop a minute.
Based out of Vienna, the industrial designer was inspired by the 2 billion people in over 40 countries who do not have access to clean water. The method of water harvesting is an old one practiced for over 2000 years.
Retezar explains his aim to make a self-filling water bottle as "a small, compact and self-sufficient device able to absorb humid air, separate water molecules from air molecules and store water in liquid form in a bottle."
