A Cheaper, Faster and More Effective Solar Water Purifier

Researchers at the University of Buffalo have created what they believe could be a faster, cheaper and more efficient solar-powered water purifier. With some 850 million people without access to clean water, a product like this is a necessity. A reinvention, or modernization of ancient technology, the product “involves draping a sheet of carbon-dipped paper in an upside-down V. The paper’s bottom edges soak up water, while the carbon coating absorbs solar energy and transforms it into heat for evaporation,” according to Smithsonian Magazine. It can remove 100% of bacteria and viruses harmful to those in areas in which clean water isn’t accessible. Read more at Smithsonian.
