<\/a> Ultra white paint, a cool solution to a warming planet: <\/strong>An ultra white paint developed by a team of engineers at Purdue University could reduce the need for air conditioning in buildings as the world continues to warm, The New York Times<\/a> reported last week. The paint, which is a Guiness World Record holder as the world\u2019s whitest paint, now has the world waiting. \u201cWe weren\u2019t really trying to develop the world\u2019s whitest paint,\u201d said Xiulin Ruan, a professor of mechanical engineering at Purdue University. \u201cWe wanted to help with climate change, and now it\u2019s more of a crisis, and getting worse. We wanted to see if it was possible to help save energy while cooling down the Earth.\u201d<\/p>\n

How it works:<\/strong> The paint \u2014 first unveiled in 2020 \u2014 can reflect 95% of the sun\u2019s rays away from Earth and into space. Since that announcement, the team has developed a formula that raised sunlight reflection to 98%. The paint can make surfaces up to 8\u00b0F cooler than air temperatures at midday and up to 19\u00b0F cooler at night. This would help reduce temperatures inside buildings and slash the use of ACs by nearly 40%.<\/p>\n

Don\u2019t expect it to roll out soon:<\/strong> The paint won\u2019t be ready for commercial use for at least a year, Ruan said. His team is also working on developing colored paints that use the ultrawhite as a base. \u201cThey will work less ideally than the white, but better than some of the other commercial colors,\u201d he said.<\/p>\n

Not fully-climate friendly:<\/strong> The standard version of the ultra white paint uses barium sulfate, which needs to be mined in a process that produces carbon emissions. However, Ruan says it creates no more damage than producing regular commercial paints, which use titanium dioxide that also has to be mined.<\/p>\n","protected":false},"excerpt":{"rendered":"
