Off-grid sterilization

Read the full story in R&D Magazine.

Rice Univ. nanotechnology researchers have unveiled a solar-powered sterilization system that could be a boon for more than 2.5 billion people who lack adequate sanitation. The “solar steam” sterilization system uses nanomaterials to convert as much as 80% of the energy in sunlight into germ-killing heat.

The technology is described online in the Proceedings of the National Academy of Sciences Early Edition. In the paper, researchers from Rice’s Laboratory for Nanophotonics (LANP) show two ways that solar steam can be used for sterilization—one setup to clean medical instruments and another to sanitize human waste.
