It’s getting simpler and cheaper to chill out: US scientists have developed an ultra-cool white paint that can reflect more than 95% of the sun’s rays and keep the house cooler on the hottest days. Across the Pacific in Singapore, researchers have developed a “smart window” clever enough to block the incoming sunlight and regulate the building’s internal temperature. It’s pretty good at blocking the noise from the streets, too.
