New Tech Harvests Drinking Water From (Relatively) Dry Air Using Only Sunlight

A device that makes enough liquid for one person to survive in the desert literally harvests the equivalent of a soda can’s worth of water from the air in an hour, Science News reports. It’s still only a prototype, but scientists hope that similar water-from-air devices can be created to produce enough water for entire communities.

This is exciting news with the potential of addressing water needs around the world — a condition that literally has become a crisis as the commercial war on water is hitting us all heavily. From expanding agricultural uses to contamination to droughts and a burgeoning world population, water is an endangered product.

Only about 3 percent of the water on Earth is fresh water, which is dependent on rain for replenishment. Fresh water stored in aquifers, meanwhile, is being increasingly depleted, at a rate that cannot be naturally restored. Not only that, pollution has left water largely undrinkable while industry (often the same ones responsible for the pollution) is draining underground aquifers at alarming rates.

Some farmers are responding by using new forms of irrigation technology and farming methods to improve water efficiency, but even so, it’s still a question as to whether it will halt the impending water crisis. It's going to take change on a global scale — to industry, agriculture and public policy — to stop the water pollution that's already taking a health and environmental toll, but you can also act on an individual level to help the problem and protect yourself. For starters, choose organically grown foods, which are grown without the synthetic fertilizers that are now devastating so many waterways.

In addition, it's best to assume yours is less than pure and take steps to remedy it, such as using a high-quality water filtration system. To be certain you're getting the purest water you can, filter the water both at the point of entry and at the point of use.
