Flash-white paint developed by Purdue University research team to comb- The New Indian Express | Rare Techy

Now there isn’t a plane, train or car idling on the tarmac, station or parking lot that doesn’t need the air conditioning turned on on a hot, sunny day. A painting is now available for you to work on. The ultra-white paint was developed by Xiulin Ruan’s research team at Purdue University late last year as an initiative to combat global warming.

It’s a new commercial-ready avatar with a thin texture that can be sprayed on cars, refrigerators and spaceships. The whitest paint on record, its average cooling power is 113 watts per square meter and reflects 98.1 percent of the sun to cool the surface by seven degrees Celsius.

The heater is a shade under the original paint that was developed last year. Being 80 percent lighter makes it an ideal coating for spacecraft.

Researchers believe that paint can reduce our dependence on greenhouse gases in the near future. Unlike other heat-dissolving paints on the market made with titanium dioxide, the one developed by Purdue University uses barium sulfate, a UV-reflective compound that known.

The component is already used to make jewelry, photographic paper, oil paint, X-ray testing and other applications.

The miracle chemical is also a climate hero because, according to the experimental model, it covers only 0.5 to 1 percent of the earth’s surface with a super-white paint that contributes to global warming.
How cool is that!

Why is paint better than AC?

Reducing reliance on air conditioners means less energy consumption. As a result, the paint has an indirect effect on the burning of fossil fuels. Also, air is known to work on the principle of convection.

To cool the inside, the hot air is pushed out, and it stays around and gets hotter. Modern painting, on the other hand, works on the principle of radiation. When electromagnetic waves are emitted, they do not remain in the environment but travel through the air into deep space.

At least, that’s the theory.
