Right. Cuz the photons are the same temperature as the sun. That's why sun photons feel warm.

- shasta 16y agoInteresting, thanks. It seems plausible that it isn't possible to redirect light from a uniform temperature black body to produce a higher temperature somewhere else. I'll have to think about it more, though. The thermodynamical argument made in that thread seems flawed to me.
