Water is the most precious resource we have, but it's in dangerously short supply. Just imagine if we could extract this life-giving fluid directly from the air around us, using solar power to cool and condense the molecules into liquid.

That's exactly what the amazing Fontus water bottle can do, and we predict it's going to be the future must-have accessory for all bikers, hikers and adventurous souls. More importantly, this invention has the potential to save lives in the developing world!

Fontus bottles never run dry, and are capable of harvesting up to 0.8 liters of water in an hour under the right climatic conditions. The technology uses a small solar panel to cool humid air into condensation, which then magically fills up your drinking bottle with water, as demonstrated by these images:

Warm air enters the bottle with the aid of a small solar panel

The humid air condenses

And Voila! The bottle is filled with fresh, clean water

The bottle is the brainchild of a young team of innovators from a small company called Fontus, based in Vienna, Austria. They each have diverse backgrounds in business, engineering or design, and they say their mission statement is to create innovative green solutions for a higher quality of life ("on a global scale").

Fontus points out that water has been harvested from the air for more than 2000 years. "The project was an attempt to discover these resources," the group says, adding:

The Earth's atmosphere contains around 13,000 square km of mostly unexploited freshwater. Fontus was invented to bring an alternative way of collecting safe drinking water to regions where drought and unclean water are a big issue."
