have you ever seen a detailed photo of the ISS? * https://images2.imgbox.com/64/4b/GhtUtq1m_o.jpg https://images2.imgbox.com/64/4b/GhtUtq1m_o.jpg look at how massive the solar panels and more importantly the thermal radiators are outside compare to the size of the human habitat tubes "AI" in space would demand as much if not even more for each node

The hotter you are, the less radiators you need for the same heat dissipation. The ISS needs to run at human-comfort temperatures, but a datacenter can run much hotter than that (note the "at 60 °C" in the article). I forget the scaling parameter, but it's like T^2 or T^4 or something like that, so running hotter makes a huge difference. Of course, that's offset by the enormous heat output of a datacenter. I'm not saying it's viable, just that you actually need to do the math instead of eyeballing the ISS radiators.

  I am curious to see if this causes an improvement in radiators though, that would be interesting or perhaps a whole new technology invented to vent the heat will be interesting to see what they come up with hmm, how do they radiate the heat from the capsule with humans going to the moon, now I am really curious, I've never seen panels like that on the lunar module past or future

Looks like the regular exterior of the service module provides enough area for heat exchange.
