Calling all active travelers! Designer Kristof Retezár has designed a product that adds a bit of magic to summer's muggy months. Meet Fontus, a self-refilling water bottle that attaches to a bicycle and turns humid air into drinking water. You read that right: This bottle turns air into water. 

The bottle uses a thermoelectric cooling mechanism (a fancy word for a device that cools down a given material) to collect air as the bicycle moves. The two-chamber device pulls in the outside air and sends it through the cooling device to be collected as condensation in the second chamber. The entire process is solar-powered, adding another eco-friendly layer to the contraption. According to a write-up on Treehugger, the bottle can produce up to 0.5 liters in ideal conditions (around 68 degrees Farenheit with 50 percent humidity).

Fontus does have a filter to keep out bugs and other sizable pests form the drinking water, but currently does not filter out smaller contiminants or pollutants. That being said, best to keep this device for remote trips. Naturally, this kind of design could also come in handy off of the bike for high-humidity areas around the world with little access to drinking water. Fontus is not yet on the market, but the project was shortlisted for a 2014 James Dyon Award.
