Drink Up Some Humidity

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.
