Dew-harvesting 'web' conjures water out of thin air

A portable dew-harvesting kit inspired by a spider's web is being developed by Israeli architects for use in areas where clean and safe water is scarce.

In February 2007, UK engineering firm Arup and charity WaterAid held a competition aimed at finding new technologies to help people gain access to clean water in areas where it is scarce. This is a problem for about 1 billion people worldwide.
