tilkusarvestust
Tilkusarvestust, literally "drop harvesting," is a term used to describe the process of collecting moisture from the air through condensation of microdroplets on specially designed surfaces. It is a form of atmospheric water harvesting. The concept combines physics of condensation with surface engineering to maximize droplet formation and collection. In practice, tilkusarvestust employs passive collectors such as dew-collection plates, cooled surfaces, or hydrophilic membranes, and sometimes active elements like fans or pumps to transport collected water. It is studied as a potential solution for water-scarce regions and disaster relief, offering low-energy water production when ambient humidity is sufficient. Efficiency depends on humidity, temperature, surface properties, and design geometry. Typical designs feature sloped collection surfaces, channels to guide droplets, and filtration systems to improve potable quality.
Advantages include low energy use and potential scalability for small communities; limitations involve variability with weather
