Whitest paint in world created at Purdue, may help curb global warming
Guinness World Records book as the whitest ever made.
So why did the scientists create such a paint? It turns out that breaking a world record wasn't the goal of the researchers: Curbing global warming was.
“When we started this project about seven years ago, we had saving energy and fighting climate change in mind,” said Xiulin Ruan, a professor of mechanical engineering at Purdue, in a statement.
The idea was to make a paint that would reflect sunlight away from a building, researchers said.

Making this paint really reflective, however, also made it really white, according to Purdue University. The paint reflects 98.1% of solar radiation while also emitting infrared heat. Because the paint absorbs less heat from the sun than it emits, a surface coated with this paint is cooled below the surrounding temperature without consuming power.
Using this new paint to cover a roof area of about 1,000 square feet could result in a cooling power of 10 kilowatts. “That’s more powerful than the air conditioners used by most houses,” Ruan said.
