    You’re right: it’s probably not practical to paint a building with the stuff. Nighthawkinlight briefly comments on this. I believe the idea is to use it on passive radiator panels to sink heat from a pumped coolant fluid. That way you can strategically place panels (e.g. on the roof) and control them, just like solar heating panels.
