The whitest-ever paint has been produced by academic researchers, with the aim of boosting the cooling of buildings and tackling the climate crisis. The new paint reflects 98% of sunlight as well as radiating infrared heat through the atmosphere into space. In tests, it cooled surfaces by 4.5C below the ambient temperature, even in strong sunlight. The researchers said the paint could be on the market in one or two years. White-painted roofs have been used to cool buildings for centuries. As global heating pushes temperatures up, the technique is also being used on modern city buildings, such as in Ahmedabad in India and New York City in the US.
