High Reflectance Roof Paint

Hi Hish,

I think this paint only reflects solar light and does little to encourage heat transfer.

Here's an interesting research project: http://www.sciencemag.org/news/2017/02/c...uches-10-c

These guys created a film composed of glass beads and backed by a silver mirror. The mirror reflects 96% of the sun's energy and the glass beads absorb heat from the body that the film is in contact with, it could be our bus rooftops. The glass beads then resonate and radiate the heat into outer space as infrared energy. According to the article, this film can passively cool any surface by as much as 50 deg F.
