One in 10 people on Earth lack access to safe water , which is why artist Ap Verheggen has been working so hard to address water scarcity over the last decade or so. He and the rest of the SunGlacier team, invited by the Dutch Ministry of Defense, recently tested their idea of making water from thin air in what they describe as the driest, hottest place on the planet: the Sahara Desert . They were able to accomplish the feat solely with the power of the sun and a bit of basic physics. Take a closer look at their groundbreaking Desert Twins , designed specifically for this project, after the jump. From an ice-making leaf in the desert to a solar-powered desert waterfall , SunGlacier has pioneered creative, artistic approaches to the lack of water in Earth’s dry areas. They recently made water from air in Mali with the solar-powered Desert Twins, two devices built for the Sahara Desert test. One device makes water, the other houses an energy unit. Condensation enables the devices to create water.

According to the team, air in Mali on a summer day only has around half the water vapor of a dry summer day in the Netherlands. They faced several days of challenges as they tinkered with their devices, adding insulation and re-configuring cooling air streams before they finally succeeded in producing any water. The team knew their design could operate in ideal conditions, but the Mali success shows it can work just about anywhere in the world. SunGlacier says their device is “probably the world’s first artificial water well to work entirely off the grid .” SunGlacier intends to keep improving their technology, and say in the future they plan to focus on cleaning and enriching water with salts and minerals, and water storage. Their goal is to build a machine that is able to operate without electricity or a liquid water source, much like a well. + SunGlacier Via SunGlacier Images courtesy of SunGlacier
