This is Fontus, a self-filling water bottle that turns air into drinking water. It extracts humidity form the air and condenses it into drinkable water. Humid air flows into the device and hits a series of hydrophobic surfaces. The hydrophobic surfaces turn the water vapor into actual droplets.A small solar panel on the top of Fontus keeps a batter charged. It includes a filter at the top to keep dust and bugs our of the water.It can produce 0.5 quarts (0.5 liters) of water in 1 hour.
