Almost 20% of the world’s population has no access to electricity, according to the International Energy Agency. Without electricity, people in developing regions can’t run modern-day sanitation and sterilization devices needed to prevent the spread of infectious diseases.

To address this problem, a research team led by Naomi J. Halas of Rice University has engineered a portable sterilization apparatus—an autoclave—that generates steam by using sunlight and metallic . . .
