A robot that cleans water with sunlight

Researchers have developed a novel, self-propelled water purifier that combines photocatalysis, photothermal evaporation, and robotics, utilizing sunlight as its sole power source. This innovative technology, comprised of a foam made from graphene oxide, MXene, and titanium dioxide, holds the potential to provide decentralized, sustainable access to clean water, especially in remote or disaster-stricken areas.
