Water harvesting from fog using building envelopes: part I
2018
New sources of clean water are currently being researched and implemented, to face global water shortage. Techniques such as desalination or cloud seeding can have a high yield but present problems such as excessive energy consumption or consistent environmental impacts. Fog harvesting stands out for being considerably simpler and inexpensive compared to the previous. In the last decades researchers have developed detailed studies and numerical models, supported by a number of successful examples located mainly in arid or seasonally arid climates. This study surveys existing methods to collect water from fog, such as drop coalescence on vertically placed meshes, chemical absorption and desorption and radiative condensers. Yields from different collectors are compared and some considerations on influencing climatic factors are discussed, suggesting that radiative systems may be applied on building envelopes as collection devices. A follow‐up paper will present experimental results on applying radiative collection systems in buildings.
