‘Smart’ Windows Block Heat, Not Light

Facebook X LinkedIn Email
A new kind of smart window blocks out heat when the outside temperature rises, potentially reducing the use of air conditioning. Developed by researchers from several Chinese institutions, the windows turn an opaque white in response to external heat; this prevents heat from entering while still allowing light through. The windows become transparent again as temperatures drop. Current methods for making smart windows use jelly-like materials called hydrogels that swell in the heat, which hurts performance. The new smart windows incorporate microscopic hydrogel beads...Read full article
