Self-Filling Water Bottle for Your Bicycle
Solar-powered device converts moisture in the air into safe drinking water
Cycling is a good way to work up a thirst, but how do you ensure you always have some water to hand – even without a water source? The answer is Fontus, a self-filling water bottle designed by Kristof Retezar that collects the moisture contained in the air, condenses it and stores it as safe drinking water. Powered by solar cells, it can harvest up to 0.5 litres of water in an hour´s time – assuming you have the right climatic conditions.
Retezar conducted a series of experiments to try and identify the ideal conditions, materials and cooling systems for his water bottle. His high-tech laboratory also happened to be his bathroom, where he simulated different climatic conditions by modifying the air temperature and humidity.
