Academic researchers have reportedly produced the brightest ever white paint, capable of reflecting 98% of sunlight and radiating infrared heat into space. Could this be key to tackling the climate crisis?
My fellow Thred enthusiasts, we’re quite possibly looking at a game changing all-natural air conditioner, and it comes straight from a tin.
Academic researchers have reportedly developed a white paint so bright it could prevent us from emitting between 600 million and 1.1 billion tons of carbon dioxide by 2050 through artificial cooling systems.
If you’re privy to a bit of travelling, or a villa holiday in the summer somewhere with heights of 30+ degrees, you’ll no doubt have noted how white paint is used to keep the exterior – and thus the interior – of buildings cool.
This reflective method has been employed for centuries and is widely effective, but as global temperatures continue to rise it is becoming less so. White outdoor paints available on the market today reflect 80% to 90% of sunlight but unfortunately cannot cool a roof to below air temperature.
A new grade of what’s being described as the ‘whitest paint on record’ may not just be the answer to mitigating this issue, but could position us to one day replace powered air conditioning almost entirely.
Developed by Scientists at the University of Purdue in India, this ultra-white paint is capable of reflecting up to 98% of sunlight and crucially can cool surfaces by up to 4.5 degrees.
For context, if you were to cover the exterior of a roof area around 1,000 square feet in this paint, leading professor Xiulin Ruan claims ‘you could get a cooling power of 10 kilowatts.’
