Did Purdue Researchers Invent the Whitest Shade of White Paint?
And it has an ecological purpose that could fight global warming.
In 2021, Guinness World Records named paint developed by researchers at Purdue University the world's whitest.
In September 2021, Snopes saw social media posts claiming researchers at Purdue University in West Lafayette, Indiana, had invented a paint that received a Guinness World Records title for the being the whitest in existence.
The assertion was accurate.
In a Sept. 20 news release, the university announced the 2022 edition of Guinness World Records features the paint formula developed by mechanical engineering Professor Xiulin Ruan and his graduate students. Additionally, the website for the records indeed lists the Purdue researchers’ “barium sulphate paint” as the world’s whitest.
But that isn’t the paint’s only special quality.
The paint made news headlines months earlier in spring 2021, soon after the American Chemical Society published a report written by Ruan’s team.
In that publication, as well as an April news release by Purdue, the researchers explained how the white paint reflects up to 98.1% of sunlight, and simultaneously sends infrared heat away from its surface — a process that could help keep buildings cool without so much air conditioning, unlike similarly designed products. (For comparison, other paints that aim to reject heat only reflect 80%-90% of sunlight and do not contain properties to make surfaces cooler than their surroundings, according to the release.)
“If you were to use this paint to cover a roof area of about 1,000 square feet, we estimate that you could get a cooling power of 10 kilowatts. That’s more powerful than the central air conditioners used by most houses,” Ruan said in the April release.
In other words, the paint has the potential to help buildings rely less on air conditioning systems that are responsible for a portion of the world’s greenhouse gas emissions, according to the researchers.
The Guinness World Records’ website stated:
Such paints are considered to be a potential game-changer for keeping the planet — particularly cities — cooler and reducing electricity use; buildings with a coating of this would need to rely far less on energy-hungry air conditioning. […]
[The] scientists estimate that it would only require 0.5–1% of Earth’s surface to be coated in this paint (e.g., by painting roofs) to reverse global warming to date.
As of April, Ruan’s team was working with a company to produce and sell the paint, according to the BBC.
“I already had an inquiry from a museum that wants to put up a display of our whitest white paint side by side with the blackest black,” he told the news outlet.

I'm not white, but my efforts will benificially contribute.

I can only answer the title, because the post is dumb as fuck.
Whites are a liability to the planet. They are homicidal and suicidal, genetically. If they're not mass murdering with the ultimate fruits of the enlightenment, they're cutting off their own fucking dicks, probably more due to the exorbitant cost of raising their children than to fit snugly into their tights.
Diluting them out of existence is the only solution.

Op post is fine but it’s literally talking about white paint and not white people which makes this a clickbait thread as usual with stl1

Would you rather it be a white supremacist thread?
Count your blessings.

you should paint 0.00001% of earth with your brains

Title misleading. This could be user conundrum. Nevertheless, I'd use it if it kept the house cool.

just make concrete white hurr durrr

The thing is that with any cool technology it needs to be durable and cheap to be widely deployed. Like how does this ultra white paint hold up against rain and pollution?
