I get skepticism that orbital datacenters will make sense economically. It would not surprise me if they never happen.

But if they made economic sense, then they would be much more environmentally friendly. On CO2 emissions, we're talking about a factor of 37. That's not a small amount. Even a factor of 10 would be a major issue multiplied by terawatts of power. Sure, maybe Earth-bound energy gets cleaner, but it's not going to get 10 times cleaner before 2036.

Currently we’re not on that trajectory but if we don’t get there we might be too busy with civilizational collapse to need space data centers.

It would require doubling the rate of 2025 renewable deployments on average for the next 11 years so technically and economically it’s feasible.

What aspect of an orbital data centre makes it more environmentally friendly than a terrestrial one?
