Tiivistelmä
Atmospheric water harvesting has the potential to serve as a reliable source of drinking water in an increasingly water-scare world. The current most common method of accomplishing this is very energy-intensive, which limits the technology considerably.
The objective of this thesis was to give an overview over current methods of atmospheric water harvesting found in literature, as well as to explore the possibility of collecting water by using an electroosmotic pump to desorb a hygroscopic material. A hygroscopic material can passively dissipate the heat of condensation, so if the water can then be collected without inducing evaporation this could avoid the large energy cost associated with directly forcing the phase change of water through heat or cold.
