Nissan develops "cool paint" technology that lowers roof-panel and interior temperatures, potentially reducing air conditioning usage.

Japanese automaker Nissan has developed a "cool paint" technology that lowers vehicle roof-panel temperatures by 12°C and interior temperatures by 5°C, potentially reducing air conditioning usage and easing strain on engines and electric vehicle batteries. The paint, six times thicker than conventional paints, reflects sunlight more effectively and emits electromagnetic waves that block solar rays. Nissan tested the technology at Tokyo's Haneda airport in collaboration with Radi-Cool of China, which specializes in heat-reducing materials.
