New self-filling water bottle harvests drinking water from the air

A new self-filling water bottle has been invented that can not only serve as a nifty device for long bike tours and races, but could also offer a new method of fresh water collection in parts of the world where groundwater sources are hard to come by.

Developed by industrial designer Kristof Retezar from Austria’s University of Applied Arts, the new device - called the ‘Fontus’ - works best in humid weather, which allows it to condense the moisture in the air into safe, fresh drinking water. Experiments have shown that under the right weather conditions, it can produce 0.5 Litres of water in just under an hour.

"My goal was to create a small, compact and self-sufficient device able to absorb humid air, separate water molecules from air molecules and store water in liquid form in a bottle,” says Retezar at the James Dyson Award website.

Retezar says he was inspired to invent the device as something that could be beneficial to some of the 2 billion people in more than 40 countries that live in regions where clean and safe sources of water are scarce. According to the UN, by the year 2030, 47 percent of our global population will be living in areas of high water stress. So he decided to take a 2,000-year-old technology - ancient civilisations from Asia and Central America were some of the first to employ it - that taps into some of the 13,000 kilometres cubed of fresh water held in the Earth’s atmosphere.

Scenes from Central Florida

I very much prefer this hidden side of Central Florida as compared to the theme parks which it is known for. Taken from this afternoon’s 14 mile bike ride on the Van Fleet State Trail. All photos taken with my phone and processed with VSCO Cam.
