New Device Collects Water Out Of Thin Air To Hydrate Cyclists

A new invention aimed at ensuring cyclists stay hydrated may have applications in developing nations where water scarcity is a major challenge.

Fontus is a self-filling water bottle that converts air into water while someone rides a bike.

"This device 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 0.5L of water in an hour's time under the right climatic conditions," according to Kristof Retezár, an industrial design student at the University of Applied Arts in Vienna who created the project.

Retezár conducted many of the experiments that led to Fontus in his home.

"I simulated different climatic conditions in my bathroom, modifying the air temperature and humidity. After more than 30 experiments, I finally achieved a constant drop-flow of one drop of condensed water per minute. After developing a functioning inner system, I designed a compact and practical hull which can be easily attached to a bicycle, integrates the water bottle and can be comfortably handled," he said.

Retezar explained the potential applications for his invention, which is competing for a James Dyson award.

“Fontus can be applied in two different areas,” Retezar said, per the Christian Science Monitor. “Firstly, it may be interpreted as a sporty bicycle accessory [that’s] useful on long bike tours. Secondly, it might be a clever way of acquiring freshwater in regions of the world where groundwater is scarce but humidity is high.”

It remains to be seen what will happen with Fontus. "It’s just a prototype at the moment, and there doesn’t seem to be any plans for commercialization. But the product could be very interesting for outdoors enthusiasts who might want to venture out, away from the grid, for extended periods," Oh Gizmo! reported.
