Are you a cyclist? If the answer is positive, you must have certainly thought, even once, how perfect it would be if there was a self-filling water bottle for bikes, so you will never be thirsty on the road.
The answer to your need is Fontus!
Fontus is a self-filling water bottle for your bicycle.
It collects the moisture contained in the air, condenses it, and stores it as safe drinking water. It is powered by solar cells, and it can harvest up to 0,5 l water in an hour under the right climatic conditions.
A second use of this device might be for acquiring freshwater in regions of the world where groundwater is scarce but the temperature and the air humidity is high.
Here are some photos of Fontus:
