FH Münster University of Applied Sciences graduates Louisa Graupe and Julika Schwarz have designed a 3D-printed prototype device aptly named Water from Air. They claim the device can produce up to 1.6 gallons of clean drinking water per day using nothing but air. A recent paper by researchers at Arizona State University estimates that up to 12 percent of U.S. residents may be experiencing water insecurity. The World Economic Forum estimates that around 72 percent of people worldwide experience some form of water insecurity. In theory at least, a household could use a Water from Air device during the day to collect the amount of water they need.
