Super cool white paint basically creates ‘free air conditioning’ – CNET [CNET]
The researchers published their results in the journal Cell Reports Physical Science.
“Your air conditioning kicks on mainly due to sunlight heating up the roof and walls and making the inside of your house feel warmer. This paint is basically creating free air conditioning by reflecting that sunlight and offsetting those heat gains from inside your house,” said study co-author Joseph Peoples.
Developing the paint was a multi-year process involving a lot of testing of different paint formulations. The team ultimately hit on calcium carbonate (a compound found in chalk, limestone and seashells) as a main ingredient.
