It took Austrian designer Kristof Retezár more than 30 different trials in his bathroom, where he tinkered with temperature and humidity to mimic different climates, before he perfected his newest creation — a self-filling water bottle that could be a game-changer for bikers and water-scarce countries alike.
Christened the “Fontus,” Retezár’s solar-powered water bottle is meant to attach to a bike frame. Depending on how hot and humid conditions are, it can generate up to 17 ounces of water by absorbing humid air as it passes over a two-piece mechanism that converts it into cool, drinkable water. Right now it’s also competing for a James Dyson Award, the Academy Awards for design engineering.
