This Bottle Can Turn Air Into Water.

Categories: Gadgets

What if there was a device that could "pull" moisture from the air and transform it into drinking water? That's the idea behind Austrian designer Kristof Retezár's Fontus, a "self-filling" water bottle that can make water out of thin air.

Created by Kristof Retezár, an industrial design student at the University of Applied Arts in Vienna,  the gadget collects and condenses moisture from the air while a bicycle is in motion. It then fills up a water bottle attached to the bike frame.


The solar-powered bike accessory uses a Peltier Element to generate water. It's essentially a cooler with two chambers that facilitates condensation, and takes in air as the bike moves, which is then slowed and cooled down by barriers that allows it to condense and form water, which is channelled and collected in the bottle.

The gadget can produce 0.5 liters of water in an hour, and works best when temperatures are around 20 degrees Celsius (68 degrees Fahrenheit) and humidity is around 50 percent. Of course, the Fontus wouldn't be suitable in urban areas where there might be polluting particulates in the air. Though there is a filter to keep bugs out of the condensed water, there isn't one for contaminants, yet.

Named after the Roman god of wells and springs, “Fontus” uses the principle of thermoelectric cooling, in which an electricity-powered heat pump transfers heat from one side of a container to another.

Fontus is still in the prototype stage. The design was recently a finalist for the 2014 James Dyson Award, an international design competition.
