Harvard scientists design new material to harvest water from thin air
Q. Which are the plants that can harness water from thin air?- Published on 26 Feb 16a. Cactus
b. Pitcher Plant
c. Geraniums
d. Both a and b
ANSWER: Both a and b
Harvard scientists have designed a new material akin to organisms such as cacti, pitcher plants and desert beetles which harvest water from thin air. This is the first step towards developing a system that can collect water and guide it to reservoirs. While the Namib beetle collects water droplets on the bumps of its shell, the V shaped cactus spines move droplets into the body of the plant. Complex bioinspired approach involves the use of these natural systems and SLIPS/Slipper Liquid Infused Porous Surfaces Technology to collect and direct flow of water droplets that are condensed.
