The amount of folks who have melted their patio furniture with their sliding glass windows will always amuse me, but overall I don’t consider IR radiation to be a big problem. Using a bunch of VOCs to paint everything and pollute a city would be though.
Comment on Nissan develops paint that keeps cars cool in summer heat
Alexstarfire@lemmy.world 2 months agoProbably yes, but it may not actually be doable. Not just because of how much there is to paint, but because the energy doesn’t just evaporate. It’s got to go somewhere. In this case I’m assuming it’s reflected, even if diffused. If everything does this, things that don’t (people, cars, pets, etc) will get all that extra energy.
Wouldn’t want to end up in a situation like this: businessinsider.com/death-ray-skyscraper-is-wreak…

You ever seen that curved building that focused the sunlight into a spot in front of it and melted cars? Lol

Ok, so don’t paint it on any concave surfaces. Most buildings have flat or convex surfaces.

Dude your mom only has convex surfaces

It can reflect it out to space. It is possible to make paint the keeps things below ambient. Obviously you’re correct, but only for things not facing upward. Upward facing things will bounce the energy back away from Earth.
