Artificial fibres that may accumulate water from the air, very similar to how spider silk gathers dew, might be used for large-scale water assortment from fog.
In locations the place the provision of ingesting water will be low, harvesting water from air tends to be an energy-intensive course of. Condensation, a typical technique, often requires a floor that’s saved cooler than the air temperature.
Now, Yongmei Zheng at Beihang University in China and her colleagues have designed synthetic microfibre threads coated in spiral-shaped bumps that may passively entice big droplets of water to condense on them.
