Water from Air – Might be good for survival

…a four-sided structure shaped like an inverted pyramid, with each panel about 3 metres tall.At night, dew drops bead up on both the tops and undersides of the panels. Because the dew collecting on top may contain dust, dirt or insects, that water could be used for irrigation. But dew from the underside is drinkable.
Gravity draws the drops downward into tanks, wells or bottles at the bottom.
A 96 square metre structure can extract a minimum of 48 litres of fresh water daily. But the dimensions can vary, says Cory, from a small personal unit that fills a water glass to several large-scale units that provide water for a community.
The low-tech approach requires only low-cost materials and is quick and easy to deploy, says Cory.
