Over a quarter of a building’s energy is lost through today’s glass-pane windows. Inspired by the color-changing skins of squids and krill, newly designed liquid-filled panels dynamically change how they let light through. Retrofitting windows with these panels could cut the energy costs of heating, cooling, and lighting buildings by well over 40%. The device moves various liquids—dye solutions, glycerol, and carbon powder suspensions—through channels carved into thin plastic sheets, using simple, relatively inexpensive, non-toxic, aqueous fluids.
