A low-tech way to turn dew into fresh, usable water has been developed by two architects at the Technion-Israel Institute of Technology. Inspired by the dew-collecting properties of leaves, the invention can extract a minimum of 48 liters of fresh water from the air each day. Depending on the number of collectors used, an unlimited daily supply of water could be produced even in remote and polluted places. Their invention recently won an international competition seeking to make clean, safe water available to millions around the world. The brainchild of Technion Architecture and Building Planning grad student Joseph Cory and his colleague Eyal Malka, "WatAir" is an inverted pyramid array of panels that collects dew from the air and turns it into fresh water in almost any climate. According to Cory, WatAir can be easily incorporated into both rural and urban landscapes because it has a relatively small base. Its vertical and diagonal design utilizes gravity to increase the collection areas. The panels are flexible and easy to collapse when not in use, and provide shelter from rain and heat and play areas for children. The project was selected from 100 entries from North America, Europe, Africa and Asia as the winner of the "drawing water challenge" sponsored by Arup - a global firm of designers, engineers, planners and business consultants specializing in innovative and sustainable design. "WatAir is a wonderfully simple concept which draws its inspiration from nature," said competition judge Jo da Silva. "This is a simple and effective idea using tried and tested technology."
