Rainwater harvesting/Fog harvesting system

Fog collection (or fog harvesting) is an innovative, environmentally appropriate, socially beneficial and economically viable use of fog, rain and dew as sustainable water resources for people in arid regions of developing countries. Fog is composed of enormous numbers of tiny water droplets. The wind blown droplets can be collected by a plastic mesh. Typical fog harvesting in a well selected desert environment would be 5 liters of water per square meter of mesh per day.
