AI summary: Researchers at the University of Massachusetts Amherst and the Lisbon-based Catcher project are developing technology to generate electricity from humidity in the air. The teams are using nanowires and nanopores to create a small but continuous electric current. Despite challenges such as microbial contamination and high initial costs, experts are optimistic about the potential of this hygroelectric power. The technology could offer a renewable energy source that operates day and night, indoors and out, and could even be incorporated into building materials.
