7. Fog-Harvesting Mesh

Researchers have developed lightweight polymer meshes with micro- and nano-scale surface features that mimic desert beetles, enabling water molecules to condense into droplets as air passes through. Mounted in fog-laden regions, these meshes capture and channel moisture into storage containers without pumps or power.
According to ScienceDaily, single panels yield several liters per square meter each night. This decentralized hydration offers remote villages a low-cost water source, reducing reliance on scarce wells and lengthy transport.
