Revolutionary Paint Reflects Heat and Produces Water!

Australian scientists have developed an innovative paint capable of cooling buildings while also collecting water from the air, offering a potential solution to rising global temperatures and water scarcity. The idea led to the launch of a startup named DuPoint Innovations, which aims to create advanced cooling coatings for urban buildings. Researchers say such technology could significantly reduce heat absorption in cities and lower electricity consumption caused by air conditioning usage.

The newly developed paint uses advanced nano materials made from PVDF-HFP and works through a process called passive radiative cooling. The coating reflects up to 96% of solar energy and keeps rooftops nearly 6 degrees Celsius cooler than the surrounding air without using additional electricity. Scientists also discovered that the cooler surface helps condense moisture from the air, allowing water collection. During early trials, researchers collected nearly 74 litres of water per day from a 200-square-meter rooftop coated with the paint.
