Researchers at the University at Buffalo have created a highly efficient device that uses sunlight and black carbon-dipped paper to clean water. The paper is placed in a triangular arrangement, which enables it to vaporize and absorb water with nearly 100 percent efficiency. The simple, inexpensive technology could be deployed in regions where clean drinking water is chronically unavailable or areas that have been acutely affected by natural disasters.
