Purdue researchers create the world’s whitest white paint

“A new paint developed by researchers at Purdue University is the coolest — literally. When Xiulin Ruan, a professor of mechanical engineering at the school, and his graduate students began working on this project seven years ago, they didn’t set out to invent a new paint color. Rather, they wanted to find a way to conserve energy and fight climate change. But what they found is that paint could do just that. And so Ruan and his team created the world’s whitest paint, a title it recently earned in the Guinness World Records book, a never achieved status. This paint, however, can do much more than set world records. It is considered a breakthrough in sustainability, one that could reduce or even eliminate the need for air conditioning, and thus the energy needed to power it.” (01/02/22)
