- absorption and radiation are correlated (a black surface would radiate more than a white surface when heated to 6000K (assuming they survive the temperature unchanged))
- a solid polished surface reflects better than a powder surface (thats imho a flaw in the article)
- basically you want a surface that is white in solar and black in atmospheric
- trilbyglens 3y agoExactly. The trick here is that you're exploiting overlaps in emission and absorption spectra in the atmosphere.
