![]() The original world’s whitest paint used nanoparticles of barium sulfate to reflect 98.1% of sunlight, cooling outdoor surfaces more than 4.5☌ below ambient temperature. ![]() “They mostly had two questions: Where can I buy it, and can you make it thinner?” “I’ve been contacted by everyone from spacecraft manufacturers to architects to companies that make clothes and shoes,” said Xiulin Ruan, a Purdue professor of mechanical engineering and developer of the paint. Now the Purdue University researchers who created the paint have developed a new formulation that is thinner and lighter – ideal for radiating heat away from cars, trains and airplanes. The world’s whitest paint – seen in this year’s edition of Guinness World Records and “The Late Show With Stephen Colbert” – keeps surfaces so cool that it could reduce the need for air conditioning.
