Thanks for the video!

Yes, from chatgpt:

These are so-called “radiative cooling paints.”

Here’s how they work:

They reflect almost all sunlight, so the surface doesn’t heat up.

At the same time, they emit thermal radiation in a specific infrared range (around 8–13 micrometers) that can pass through the Earth’s atmosphere and escape into space.

Such paint can make surfaces cooler than the surrounding air, even in sunlight.

So it doesn’t convert solar energy into another form — it selectively reflects and emits infrared radiation that sends heat directly into space.
