WEDEW, Creates Artificial Clouds That Can Produce Drinking Water
Teknologi.id . October 26, 2018
Judges have chosen the winner of the Water Abundance Xprize, and it might just be vital to solving some of the world's most difficult shortages. The Skysource/Skywater Alliance has earned $1.5 million for WEDEW (Wood to Energy Deployed Water), a system that converts air into drinking water using natural resources for power. WEDEW creates its own clouds within a box the size of a shipping container. Powered by wood chips and similar biomass, it draws warm air from outside and sends it through an antimicrobial air filter to remove impurities. Once inside the box, the WEDEW introduces the warm air to generated cold air inside. This produces condensation. With few running parts, the machine can run for 10-15 years, according to its company website. There's enough water within the atmosphere at any given time to fill the Great Lakes, around 3,100 cubic miles. Given the fact that this atmospheric water is constantly replenishing due to the planet's hydrologic cycle, the Venice Beach, California, company has created a system that is unlikely at the current moment to effect the atmosphere negatively. And on top of all that, keeping with the rules of the XPrize competition, it uses electricity efficiently at the cost of two cents per liter. Skysource/Skywater Alliance won the Xprize.

"Our process is one that is really antithetical to the slow-moving infrastructure that exists that is not able to be responsive to a changing climate as it is in the case of say, Cape Town, for instance,” he says, referencing the water concerns that have the South African city considering towing down an iceberg. The global water crisis isn't solved yet. A Skywater Emergency Services Unit can produce 450 to over 900 gallons in a day. That's nothing to sneeze at, but it's worth keeping in mind that the average person uses 100 gallons a day. But still, the technology is promising. And over a million dollars worth of prize money sounds like just the type of encouragement Skywater needs. You Might Also Like: Gita, Suitcase Robot with Artificial Intelligence.
