New physics-defying nanomaterial gathers water from air directly | The material works through capillary condensation, a phenomenon where water vapor turns into liquid within microscopic pores, even when the humidity is relatively low.
US develops portable device that extracts water from air using 50% less energy | The device uses special materials that change temperature when stretched or compressed, allowing it to cool the air and condense water vapor with minimal energy use.
A hydrogen-powered air taxi flew 523 miles emitting only water vapor
