Abstract

Fog harvesting is a technique used to collect waterfrom the fog. This technique became widely used around theworld due to the lack of fresh water, as fog harvesting isconsidered to represent an economical and a reliable source ofwater. On that sense, fog collecting methods are mostlyimplemented in areas that lack access to fresh water and ismostly used for agricultural purposes and, in some cases, alsofor providing clean drinking water. The basic idea ofharvesting the fog was first developed by farmers when sometypes of adjoining cavities and containers were put aroundplants to collect water from humid air, after that thosetechniques were turned into fog harvesting structures. Theintroduction of fog harvesting techniques was accompaniedwith the introduction of new materials and different structures,providing a range of options in regards to the meshes and to theharvesting methods. In this paper, a practical and theoreticalassessment of existing fog harvesting meshes is performed inorder to characterize their economic and physicalcharacteristics. The final objective is to provide informationabout their ability to perform in different conditions which is tobe added to an environmental conditioning structure forexterior spaces.
