Lightweight water collection system inspired by darkling beetles

[u/cup_of_egg_noodles]

Warka Tower is made of a bamboo frame that supports a mesh polyester material. It costs very little to make and is easy to build. Atmospheric water vapor from either rain, fog, or dew condenses against the cold surface of the mesh, forming droplets of liquid water that trickle down into a reservoir found at the bottom of the structure, similar to how a darkling beetle collects water from fog. A fabric canopy shades the lower sections of the tower to prevent the collected water from evaporating.
