Researchers have developed a solar-powered purifier, which could provide a highly efficient and inexpensive way to turn contaminated water into potable water for personal use.
The device could help address global drinking water shortages, especially in developing areas and regions affected by natural disasters, researchers said.
“Using extremely low-cost materials, we have been able to create a system that makes near-maximum use of solar energy during evaporation. At the same time, we are minimising the amount of heat loss during this process,” said lead researcher Qiaoqiang Gan, Associate Professor at the University at Buffalo in the U.S.
The team built a small-scale solar still. The device, called a “solar vapour generator,” cleans or desalinates water by using the heat converted from sunlight.
