Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

The temp is low but it is a vacuum. Vacuums are bad at dissipating heat. Think of the vacuum walled drinking vessels. They are so efficient at keeping beverages hot/cool because the vacuum insulates the majority of the surface area that heat can move across.

Likewise a cooling tank of water (typical nuclear reactor design) itself surrounded by vacuum, will not cool efficiently at all. Presumably they'd have to use piping to circulate the water over a large surface area of some other medium like the moon rock itself.

I've got it. Since we're worried about rising sea levels on earth, we can just pipe the excess water to the moon and flood the moon's surface with water and use that for cooling.

Hello, Nobel prize foundation?

Yes, this man right here!

Vacuums are bad at dissipating heat.

They're also very good at not stopping infrared radiation.

The IR band gap is high enough that you'd need really efficient heat pumps to keep things radiating well. Otherwise the heat pumps generate more heat than you can radiate.
