I'm hoping you're wrong. I just made a simplified version, which is just the concertina-ed paper without the parallel reverse folds to angle the keyboard up. Its made from a 96gsm a3 sheet.
My reasoning for thinking it's safe is that 451F/230C would probably damage/burn/melt the cheap plastic table it normally sits on.
Wouldn't you just use earthlight and normal solar panels? The internet says moonlight is 1/345th the power of sunlight but once you factor in Earth's larger radius and larger albedo you get 1/9th the power of sunlight. IE you just use 10 times as many solar panels to get you through the night.
