An article in the World Economic Forum reports on research by Qiaoqiang Gan, associate professor of electrical engineering, to develop a cheap solar still that uses sunlight to purify dirty water up to four times faster than a current commercial version.
“Using extremely low-cost materials, we have been able to create a system that makes near maximum use of the solar energy during evaporation. At the same time, we are minimizing the amount of heat loss during this process,” he said.
