Device Pulls Drinkable Water From the Air As You Cycle

Most bicycles have a place to hold a water bottle. This isn't most bicycles. Fontus—a device created by Austrian designer Kristof Retezár—takes the standard bottle holder a step further, collecting moisture from the air in order to fill an attached water bottle with clean, drinkable water.

Powered by solar cells, Fontus can collect about half a liter of H20 with an hour's worth of cycling and the correct weather conditions.

Essentially, the solar-powered cooler and the speed of the air traveling through the device condense the moisture in the air. When moist air enters the upper chamber (shown at the top right of the diagram below), it is slowed by a series of barriers, which give the air the time it needs to release its water molecules. Once properly cooled, these molecules can turn back into liquid water. The harvested H2O then flows down a tube into the bottle. 

After 30 trial runs, the designer is confident the invention works. The device will likely come in handy for bikers who don't have a lot of room to spare and don't want to make any pit stops.
