Answer:

Fog collection is the harvesting of water from fog using large pieces of vertical mesh netting to induce the fog-droplets to flow down towards a trough below. A material that can collect water from fog should be able to induce condensation of atmospheric water vapor from the air into droplets of liquid water. Some designs use parallel wires while others use tiny structures inspired by cactus spines.

When designing a material for collecting water from fog, some important criteria and constraints might include its ability to collect moisture efficiently under different conditions (such as cool fog or sunny conditions), its durability and cost-effectiveness. Additionally, bioinspired designs have been shown to be effective for collecting water from fog.
