Why ceramic and not just paint?
The article addresses that. It is because ceramics are durable while paints and coatings are not.
Seems like the effort involved in putting down paint would outweigh the durability. Perhaps they’re thinking about robots to place the tiles though, like on Starship?
Roof tiles. They want to make these into roof tiles. There is a big picture in the article and they even talk about roof tiles. Did no one read the article?
Most coatings like paint that have this effect include ceramics to do most of the reflection, but the other paint stuff the ceramic substrate is emulsified in does not have near the reflectivity, so you're impairing yourself if reflectivity/heat rejection is the only goal.
Maybe ceramics were considered more sustainable?
