World's First Self Filling Water Bottle

Self Filling Water Bottle Fontus

This is a self filling water bottle that turns air into drinking water called Fontus. As you ride your bike, air passes through the device and is condensed into drinkable water.


The stand alone version works the same way and is charged with a solar panel. As air passes through the hydrophobic surfaces, water vapor turns into drinkable droplets. Both designs can produce about 0.8 litre of water in one hour. There's a filter at the top of the bottle to keep dust and bugs out.


Imagine never running out of water again on your adventures.
