If you’re out biking, you need to keep hydrated. And to make sure that you don’t run dry, industrial design student Kristof Retezár has designed a self-filling water bottle prototype that turns air into water while you ride a moving bicycle.
Using the principle of thermoelectric cooling—where humid air is passed through solar cells that will condense moisture from the air into water droplets—the product is able to collect up to 0.5 litres of water within an hour, in countries that have the right climate of course.
“I wanted to bring a solution to many problems, including water scarcity,” Retezár said.
The Fontus is designed as a handy bicycle accessory for long bike tours, and is also a solution to water scarcity. The basic elements of the device aren’t too expensive, Retezár said. He estimated that the prototype cost between $25 and $40 to make. However, that may change depending on future iterations of the gadget, he notes. Kristof hopes to refine the device with a purification system so that it can be used in cities with pollution, and will be looking into crowdfunding options and investors to mass-produce the device.
