Researchers at MIT have created a solar-powered device that can make seawater drinkable. The team says the device can remove the salt from seawater for less than the cost of US tap water. And, to top it off, the water produced by this device could eventually cost less than US tap water, according to a paper published last week in the peer-reviewed journal Joule. Yang Zhong, a graduate student at MIT and an author of the September 27 paper, said this desalination device is more efficient, longer-lasting, and cheaper than previous desalination devices. For Qadir, desalination is a key factor in solving this water crisis.
