Only a fraction of the Earth's water is drinkable - an estimate from the U.S. Geological Survey puts all of the world's freshwater at just 2.5 percent of the total global water. What if we could diversify and pull water from the air, instead? Now, a new invention does just that. Fontus is a water bottle that pulls moisture from the air, and in ideal conditions, can fills itself up in under an hour. The water bottle comes from Austrian industrial designer Kristof Retezr, who wanted to make a simple, portable tool to help people where drinkable water isn't easy to get. The UN Department of Economic and Social Affairs reports that 1.2 billion people, around a fifth of the world's population, live in areas where water is physically scarce. Another 1.6 live in countries where water infrastructure and storage is lacking. The Fontus uses solar energy to power a small cooler or condenser that works by the so-called Peltier effect. Air passing through the cold chamber rapidly condenses like droplets on the outside of a cold glass. In "really good" conditions, or temperatures between 86 and 104 degrees with humidity between 80 and 90 percent, the Fontus can generate half a liter of water in an hour. In the future, Retezr says the company hopes to improve that so the bottle can work in more conditions. The project was shortlisted for the 2014 James Dyson Award. Next the company hopes to launch a crowdfunding campaign and get the price of the water bottle under $100.
