WatAir: A Dew-Catching Inverted Pyramid

Leaves and spiders' webs beaded with dew have inspired a low-tech solution for collecting fresh water. WatAir, an inverted pyramid made from elastic canvas, recycled polycarbonate, metal or glass, can reap dozens of litres of water a day from the air. The inexpensive solution could help bring clean drinking water to people in remote or polluted areas. Joseph Cory & Eyal Malka from Haifa, Israel have a developed a device to catch water from air. The device features 96sq m of dew collecting panels arranged in an inverted pyramid shape and they estimate each device could collect 48 litres of water a day in remote places or places with contaminated water supplies.
