Industrial designer Kristof Retezár has created a self-filling water bottle that can turn an hour of cycling into half a litre of water

A new self-filling water bottle has been created by an Austrian designer that can turn pedal power into water.

Industrial designer Kristof Retezár came up with the ‘Fontus’ self-filling water bottle design, which condenses the water in the air as you cycle, producing fresh drinking water.

According to Retezár, in ideal conditions (hot and humid) the creation will be able to produce half a litre of water from an hour of cycling.

“Firstly, it may be interpreted as a sporty bicycle accessory… Secondly, it might be a clever way of acquiring freshwater in regions of the world where groundwater is scarce but air humidity is high” Retezár said.

Fontus works by cooling the air travelling through it, then a filter traps the water in the air by condensing it, which then drips into the attached bottle.

The design – shortlisted for the 2014 James Dyson Award – could help in aid in bringing water to those in developing part of the world where it is hard to come by.

However, with the issue of air pollution, it would appear the bottle would not be much use on your commute around a city.

    Looks very un-aerodynamic and not at all racy for professionals and Sportive racers.
    What’s wrong with getting off the bike for a drink and snack? I don’t drink on the move any more.
