Could this paint replace your AC?
Scientists are developing advanced cooling paints that could help buildings stay cooler without relying as heavily on air conditioning. The secret is in how the coating interacts with sunlight.
These specially engineered paints are designed to reflect a large portion of solar radiation instead of absorbing it as heat. That can lower surface temperatures and, in the right conditions, reduce the amount of heat entering a building.
The technology could be especially useful in hot climates, where cooling systems consume huge amounts of electricity. If it can be scaled affordably, cooling paint could become a simple way to make buildings more energy-efficient.
So, could your walls help keep you cool?
