Look, hydrated lime is one of the surprisingly highly efficient ways of passive cooling, maybe you want to try it?

There's plenty of literature around it, so I'll drop just this for a food start: https://www.sciencedirect.com/science/article/pii/S235271022...

LOL. We could all be Greek! I have 2, 50lb bags of Western Miracle Type S Lime that I moved across the country to a new house and don't have a current use for. It made really awesome pavers with the gazebo excavation dirt on the previous project.

Would painting lime work on city streets, interstate freeways, and parking lots, though? I hadn't thought of that. I'm not going to look it up but an enormous number of house roofs here are pure white from some sort of white/plastic/rubber concoction.
