> You just can't reach a temperature higher than the surface of the moon itself. False. You can't reach a temperature hotter than the black body which emitted the light. The moon is a reflector which is as cold as -153 C, not a black body emitter. Try reflecting sunlight with a large mirror cooled by air to 23 C through a magnifying glass onto an object in the shade. You can still light things on fire.
