Scientists create world's 'whitest' paint, could fight global warming

Scientists at US University have created the world’s ‘whitest paint’, its white properties could fight against global warming. The paint have been developed by Xiulin Ruan, a professor of mechanical engineering and his team at Purdue University. The paint has earned a Guinness World Records book for being so white.

This white colour reflects 98.1% of solar light and also emits infrared heat, which can cool the air around buildings. It absorbs less heat than the heat emitted from the sun. This can reduce the use of air conditioners. Commercial white generally reflects only 80 to 90 per cent of sunlight.

"Typical commercial white paint gets warmer rather than cooler. Paints on the market that are designed to reject heat reflect only 80-90 per cent of sunlight and can't make surfaces cooler than their surroundings," Purdue University said in a statement.

Using the paint to cover a roof area of about 1,000 square feet could generate upto 10 kilowatts of cooling power, said researcher at Purdue researchers. According to Ruan, this is more powerful than air conditioners used in most houses.

"When we started this project about seven years ago, we had saving energy and fighting climate change in mind," said Ruan, in a podcast episode of "This Is Purdue."
