IR-Reflective Black Paint
The cluster discusses a novel black paint that appears dark in visible light but highly reflects infrared/heat radiation for passive cooling, with debates on its durability, dust resistance, wear from use, and advantages over white paints for applications like roofs and vehicles.

Maybe some transparent non-IR reflective paint?
Are the incremental improvements over regular black paint meaningful?
Wouldn't the reflectivity degrade almost immediately, as dust landed on said painted surface?
Would this actually look like bright white paint? Maybe because they're also trying to reflect light outside the visible spectrum it might not be as bright in the colours we can actually see.
My sedan has reflections from the dash on the windshield and it gets annoying in the sun. Can this paint help or will it turn into millions of lung impaling particles when the car is parked in the sun?
Just need to make sure that the white coating doesn't block radiation of heat to the building underneath when black is facing the sun.
How wear resistant is it? Presumably any coating would add reflectivity?
You can't run tires on a reflective surface and expect it to remain reflective.
Title doesn't do the article justice: the paint increases the reflectivity so over the course of time the Sun's photons deflect it.
I'm pretty sure regular black paint has aluminum to reflect a lot of energy back out.
