This is something right out of a science fiction movie, Fontus is a self filling water bottle. It uses the sun to condense and filter the moisture in the air to get drinkable water. Fontus comes in two designs, Airo which is a standalone water bottle and Ryde which is engineered to fit a bike.differences_fnrayb

Fontus Ryde and Airo might be a clever way of acquiring freshwater in regions of the world where groundwater is scarce but air humidity is high.


The Airo unit uses a small fan that pulls air in then runs it through a filter and into the condensation chambers. Small coolers bring the moisture contained in the air to condense on special surfaces. The resultant liquid water then drops into the bottle’s main body and is stored.


The Ryde unite utilizes the air stream generated while riding a bike in place of a fan. The air is then condensed across a complex cooling system. A series of small coolers powered by solar panels, attached at the sides, bring the moisture contained in the turbulent air to condense on special surfaces. The water is then stored in the bottle.
