Related" "A City on Mars" (2024) [1] A useful book on why self-sustaining settlements on Luna, Mars, or earth orbit are pretty much hopeless. Remote bases that take a lot of supply, maybe, with great difficulty. The environment is just too hostile and doesn't have essential resources for self-sustaining settlements. The authors go into how Antarctic bases work and how Biosphere II didn't.

The worst real estate on Earth is better than the best real estate on Mars or Luna.

I wasn't terribly impressed with this one. I found it mostly just a bundle of vague negativity and insufficient (disingenuous?) use of problem-solving. However if you want to try it then give the rebuttal a fair shake too.

"One modern idea that O’Neill did not consider is to move server farms in space, where power is cheap and you can dump heat into space with a black piece of metal."

Hmmm.

Minor quibble - radiators are white in the visible spectrum.

> The radiators on the ISS are a high-emissivity white paint, meaning that they are dark in the infrared spectrum where the heat is emitted. They are white in the visible spectrum to reflect sunlight.

> The radiators on the shuttle are have a two-layer coating: a silver reflective layer covered by a thin Teflon film. The Teflon layer is opaque to infrared light, so the high emissivity of Teflon dominates. Visible light passes through the Teflon layer and is reflected by the silver layer, so the solar absorbance is low.
