A solar-powered sterilizer could provide remote areas in the developing world with a portable, off-grid solution for sanitizing medical instruments and equipment, according to a study. In remote, resource-poor locations, the lack of readily availablesterilization processes for medical or dental tools increases the risk of disease propagation. Now, researchers from Rice University in the United States have developed two prototype sterilization devices that harness the sun's power: one to sanitize medical equipment and the other to sterilize human waste without the need for an external electricity source. Their work was published in Proceedings of the National Academy of Science.
