You're not just watching paint dry; Scientists from NTU Singapore have created a new method of #recycling #plastics like acrylic, PVC and polystyrene foam into a paint that can cool surfaces by mixing it with barium sulphate.
This #innovative paint makes use of passive radiative cooling, which sends heat from objects on Earth into outer space through a "window" in the atmosphere that allows certain wavelengths of heat to pass through, while reflecting most sunlight.
When tested in real-world conditions on the rooftops of the #NTUsgSmartCampus, the paint reduced the surface temperature to 1.2°C below ambient temperature during the day, and 3°C below ambient temperature at night, helping to mitigate the effects of #climatechange while boosting #sustainability efforts.
