Water harvesting from fog using building envelopes: part I

Part I The Building Blocks of Soil

Investigation of Fresh Water Harvesting from Playa’s Wetlands

Playas are low-lands which is considered to be the locations of accumulation of superficial and ground waters fromhigher elevations and these waters have different types of salts and various salinity level. Therefore, because of lack ofrainfall and fresh-water both for human and animal useage or even for plants, it is needed to apply proper methods toharvest fresh water from these saline-waters...

Water vapour in circumstellar envelopes

We present observations of the 313 →220 line of p-H2O at 183 GHz in the direction of the circumstellar envelopes of 23 O–rich evolved stars. The 183 GHz data are complemented with observations of CO J=2 →1, p-H2O 515 →422 at 325 GHz, o-H2O 616 →523 at 22 GHz and SiO v=1 J=2 →1. The line profiles of these transitions are compared and discussed in terms of the regions where they are formed. We ha...

dynamical assessment of fog harvesting based on fractal theory

abstract the limitation of water sources in most places all over the world, especially in arid and semi-arid lands is an important issue for those who live in these areas. many governments have dedicated their efforts toward finding new water resources to obtain water. fog and cap clouds harvesting are one of the candidate methods to produce pure water. many countries including chile, peru, ecu...

Optimal design of permeable fiber network structures for fog harvesting.

Fog represents a large untapped source of potable water, especially in arid climates. Numerous plants and animals use textural and chemical features on their surfaces to harvest this precious resource. In this work, we investigate the influence of the surface wettability characteristics, length scale, and weave density on the fog-harvesting capability of woven meshes. We develop a combined hydr...
