Genius Little Gadget Turns Air Into Drinkable Water As You Ride Your Bike

Have you ever been out for a run, walking a long trail, or just plain thirsty but guzzled all of the water before you can head to the next fountain? Fear not: here is a water bottle that can create instant drinking water from the humidity in the air through a simple process.

Austrian industrial design student Kristof Retezárhas created Fontus: a water bottle system that condenses humid air into clean, drinkable water.

His design made him a finalist for the 2014 James Dyson Award (an award that celebrates university student invention to inspire the next generation of design engineers). Not too shabby. Currently, The Fontus is capable of producing a drop of water per minute, in air that is approximately 50% humidity with temperatures at least 20˚C (68˚F).

The only current defeat is that this means it will take a significant amount of time to create plenty of water to swig. Retezár’s home city of Vienna is not known for its humidity, so he was forced to conduct his experiments in his restroom using steam from the shower.

The Fontus attaches to the bicycle frame and consists of a condenser unit and a bottle for collection. A solar panel on top of the unit that powers the condenser. As the motion of the bike causes air to blow into a channel, the moist air is cooled, causing it to condense. The droplets roll back down the condensing unit, collecting in a water bottle mounted underneath.


According to Live Science, “Fontus can produce 0.5 quarts (0.5 liters) of water in 1 hour in what is considered “really good” conditions, with temperatures between 86 degrees and 104 degrees Fahrenheit (30 to 40 degrees Celsius) and between 80 percent and 90 percent humidity.”





The price of each Fontus device would likely to come in under $100, and could be available sometime later this year. You can check out more of it here. What do you think? Let us know below, and make sure to give this a share on Facebook before you go. (h/t IFLS) (Photo Credits: Kristof Retezár)
