Spongy new material pulls drinkable water from thin air in emergencies | This spongy composite material made of porous balsa wood, lithium chloride, and iron oxide nanoparticles, can capture water from the air fairly efficiently
One of the biggest difficulties in helping people affected by natural disasters is transporting and providing them with essential resources like safe drinking water. Researchers at Australia's RMIT University and five Chinese institutes have devised a simple and clever contraption that could solve…
Researchers at Australia's RMIT University and five Chinese institutes have devised a simple and clever contraption that could solve that, by pulling potable water out of thin air. The team's invention uses a newly developed composite material based on porous, lightweight balsa wood shaped into small cubes; these are installed into a cup with a domed lid, a simple cooling mechanism, and an activation system powered by the Sun. Dr. Junfeng Hou from Zhejiang A&F University, who led the Chinese institutes' collaboration with RMIT, noted that WLG-15 also worked just fine after being stored at sub-zero temperatures for weeks, and could be reused multiple times without much of a decline in efficiency.
