Photothermal fabric panels could cut heating energy up to 23%

Researchers at the University of Massachusetts Amherst have unveiled a tool to combat climate change, fossil-fuel dependency, skyrocketing home-heating bills, and gentrification all at once—a simple fabric treated with a special photothermal dye that, when placed on outside walls, can help keep a home 8.64ºF warmer over the course of a day.
