Solar sterilization (IMAGE) Massachusetts Institute of Technology Caption Autoclaves, which are used to sterilize medical tools, require a steady supply of hot, pressurized steam. Researchers at MIT and the Indian Institute of Technology have come up with a way to generate that steam passively, using just the power of sunlight, to help maintain safe, sterile equipment at low cost in remote locations. This photo shows an example of the new autoclave developed by researchers. Credit Courtesy of the researchers. Edited by MIT News.
