Scientists create nanotubes that suck water from air..
We know that, water is very essential to our life. Especially in desert areas, water is a demand one. So, researchers from the Rice University
considering the life of the Stenocara beetle
in the desert areas and they noticed how that kind of beetles survives in the desert.
These kind of beetles stretches its wings and by the help of this they collect the water from the morning fog and so the beetles survives its life by this manner. The same concept is used in this nanotubes. The top of the nanotubes attracts water from the air. The bottom of the nanotube repels water. The combination traps water inside each tube for later extraction. This process doesn’t require any energy at all..
Consider areas of the world where water is scarce (and becoming more scarce thanks to climate change). What if we could grow a large forest of carbon nanotubes that collect water from the air? Of course, because carbon nanotubes are so small, it would take a lot of them, and a lot of work, to make something like that a reality. However, it’s not unthinkable that we might be able to create a cup with a nanotube forest inside it, perhaps for those adventurers brave enough to go into the desert alone.http://www.dvice.com/2014-6-12/scientists-create-nanotubes-suck-water-airsource:http://news.rice.edu/2014/06/11/nanotube-forests-drink-water-from-arid-air/
