I hope it was worth it. Refuting the assertions isn't a big deal. It's the same old naive garbage. It's the tedium of having to read that whole thing that really gets you. It's so redundant. And he needs an editor worse than I do. Somewhere in a huge paragraph of invective and name-calling and extraneous verbage might live a statement that merits an answer, but you have to wade knee-deep through all that muck to see if it's there.

I find it very amusing that someone who goes on at length about albedo hasn't tried to see if it applies to any of the earthly surfaces he's been photographing with stopped-down lenses and split-second shutter speeds. He seems to think that 10% of the light from the sun is a very small amount, photographically speaking. Most assuredly it is not.

Oh, there's an addendum to the issue of why you can't work on the earthlit nightside of the moon. The equipment does have to be kept at certain suitable temperatures. The ascent fuel, for example, has to stay at room temperature. In the dark all the heat will radiate away and there essentially won't be any. So for that equipment that has to stay above -250 F, you'd have to provide heaters. (You do anyway for some of it, but you'd need them everywhere.) That makes it heavier and use more electricity, and that means heftier batteries.

It's not very hard to control how much radiant energy something absorbs. You have isolation techniques, coatings, etc. So the sun essentially provides free heat. For equipment like electronics which generate heat, heat rejection is something of a problem. (But it would be anyway.) For biological systems (i.e., astronauts) that generate heat, heat rejection is the same problem. (Again, solvable.) But for things that don't generate heat and, but for the influx of heat from some other source, would freeze solid, there's the sun. You simply apply whatever coating brings your equipment to the desired equilibrium. You don't need to heat the ascent fuel or the gaseous O2 tank or any of the other stuff that was intentionally placed where the sun would shine on it and impart some heat.
