Ultra-White Paint to Reduce the Use of Air Conditioners

A group of researchers at Purdue University have developed an ultra-white paint that is said to decrease or even eliminate the need of air conditioning. It is considered to be the World’s Whitest paint developed dexterously at Purdue University. And it has earned a Guinness World Record. The concept behind making this paint was to help reduce global warming.

The white paint was invented by Xiulin Ruan, who is a Purdue University professor of mechanical engineering, and his students. It is hard work of seven years in the making with the purpose of saving energy and fighting climate change.

The paint created reflects 98.1% of solar radiation and it also emits infrared heat at the same time. It ends up absorbing less heat from the sun than it emits which lets a surface coated with this paint cool below the surrounding temperature, and that too without consuming power. This paint used to cover a roof area of around 1,000 square feet could result in a cooling power of 10 kilowatts, according to Purdue researchers. This is also considered to be more powerful than the air conditioners used by most houses.

Why It Is Better Than Commercial White Paint?

The disadvantage of commercial white paint that we get actually warmer than cooler. Moreover, these new innovative paints are designed to reject heat reflect only 80% to 90% of the sunlight and can’t make surfaces cooler than their surroundings. The paint would not only send heat away from a surface, but also away from Earth into deep space where heat travels indefinitely at the speed of light. This way, heat doesn’t get trapped within the atmosphere and contribute to global warming.

Earth’s surface would actually get cooler with this technology if the paint were applied to a variety of surfaces including roads, rooftops and cars all over the world, the researchers said.

We could see this white paint hitting the market soon as the researchers have partnered with a company to scale up production. The researchers have also filed patent applications for this white paint. There is strong seriousness on making this white paint available for commercial use which could help eliminate the use of air conditioners and thereby help reduce power consumption.
