NightHawkInLight · Tutorial · YouTube title: Making Infrared Cooling Paint From Grocery Store Items (w/Novel CaCO₃ Microsphere Synthesis)
Why it's here
It comes up whenever radiative cooling coatings are in the news, as a hands-on DIY guide that shows the approach working with household materials.
What it covers
NightHawkInLight shows how to make radiative sky cooling paint from grocery and hardware store materials, including a novel calcium carbonate microsphere synthesis. The paint can cool a surface below ambient air temperature in direct sunlight without electricity.
