They create white paint that cools more than an air conditioner

You won’t need an air conditioner to keep your home environment cool. Engineers from Purdue University, USA, created a white paint that cools more than any of these electrical appliances and has caused a sensation in the world of innovation.

The idea arose in an effort to stop global warming, managing to create whitest paint so far.

“If this paint were used to cover a roof area of ​​about 1,000 square feet (93 m2), we calculated that a cooling power of 10 kilowatts could be obtained. That is more powerful than central air conditioners they are used in most homes, ”said Xiulin Ruan, a Purdue professor of mechanical engineering.

The lightest white paint ever invented before

Cladding buildings with this white paint may, one day, cool them enough to reduce the need for air conditioningsay the researchers.

In the month of October, the team created an ultra white paint that expanded the limits of how white paint can be. Now they have gotten over it.

The newest paint is not only whiter, it can also keep surfaces cooler than the formula the researchers had previously demonstrated.

The extreme white created the coldest color on record. Using high precision temperature reading equipment called thermocouples, Researchers were able to demonstrate outdoors that paint can keep surfaces 10 degrees Celsius cooler than its ambient environment at night.

“We found that using barium sulfate, theoretically you can do very very reflective things, which means that they are very, very white ”, says Xiangyu Li, one of the researchers who has worked on this project quoted by El Confidencial.
