High-speed filter uses electrified nanostructures to purify water at low cost - 0 views

thinkahol * on 01 Sep 10Researchers have developed a water-purifying filter that makes the process more than 80,000 times faster than existing filters. The key is coating the filter fabric -- ordinary cotton -- with nanotubes and silver nanowires, then electrifying it. The filter uses very little power, has no moving parts and could be used throughout the developing world.
