Scientists in Hong Kong have demonstrated a new ultra-white ceramic material that can drastically cool buildings by reflecting sunlight and heat at record highs. The beetle-inspired material gets its ability from its nanostructure, stays tough to the elements and should be relatively easy to scale…

    Can mostly handle. Snow blindness is a thing, and that’s all diffuse reflection too, not specular. But it’s unlikely a roof would be such a problem.

      The reason for snow blindness is the fact the snow fills such a high portion of the visual field.

        Yeah, hence it’s unlikely a roof would fill it to the same extent and wouldn’t be a problem.
