Hybrid active fog-water harvesting device HygroCatch

An experimental prototype of the hybrid fog water harvesting device, HygroCatch, was designed and equipped with Peltier cooling elements. The basic operating modes of harvesting method were tested, with the following relative share: ionization of fog droplets in a high-voltage field (56 %), additional condensate collection based on the Peltier effect (25 %), and mechanical water collection on electrode grids (19 %). The distinctive feature of HygroCatch is its hybrid adaptability, which enables fog water harvesting across varying fog saturation parameters under conditions where other methods are not applicable.
