  • Fresh water pulled from the sky. It is an ambitious goal, but to win the Water Abundance XPrize, teams have to extract 2000 liters a day from the atmosphere in a cheap and sustainable way. The five teams through to the finals were announced last week by XPrize, the non-profit that organized the competition. These had been whittled down from an initial field of 98 based on their prototypes. Final testing will happen in July. Teams must produce the water using renewable energy at a cost of no more than 2 US cents per liter. Whichever group extracts the most water at the lowest cost will receive $1.5 million. The World Health Organization states people need at least 20 liters of water a day for drinking and basic hygiene, but increasing demand from growing populations and the impact of climate change means global fresh water supplies are rapidly depleting.
