Multiple southern states and a few midwestern states are at "extreme threat" levels of "wet bulb temperature".

I wonder. He did need the snow-scattering effect to get the barium-based pigment to work, but it seems like the dense packing achieved by the varied sizes of nanoparticles might suffice for light rejection without that effect. It didn't sound like he re-tested that with the new recipe.

Tech Ingredients also covered cooling paint and referenced the NightHawkInLight Video but they went into a bit more on application. It still needed a thick coat. https://youtu.be/dNs_kNilSjk

It's been a while since I watched that one. I'll have to give it another look. They were also using the barium pigment, but I can't remember if they used the multiple sizes of nanospheres.
