UPDATE 2: Guinness World Records has recognized this as the "world's whitest paint": https://www.purdue.edu/newsroom/relea...
UPDATE: The whitest paint in the world is now even whiter... and cooler! https://www.purdue.edu/newsroom/relea...
What if paint could cool off a building enough to not need air conditioning? Prof. Xiulin Ruan has pioneered radiative cooling paint; instead of absorbing sunlight, it radiates the heat back into space. This actually cools surfaces below ambient temperature, something paint has never done before.
