For more about this new material, go to http://cenm.ag/vapor. Harnessing heat, light, wind, and other natural stimuli to generate electrical power is a major goal in science. Now, researchers at MIT have developed a material that can generate power from an ever-present substance in the environment: water vapor. In this clip, watch sheets of the team's polymer composite tumble around a moist surface and learn how the new material's continuous motion might someday charge small devices without help from an electrical plug.
