Except you aren't leaving that heat in place.

You're concentrating it into a very small area of compute.

If you don't spread that heat back out, it's going to find a much higher thermal equilibrium than the solar panels themselves would find just absorbing the sunlight and radiating the energy back into space.

It's like you've pointed a magnifying glass at your compute, except with electricity, which means you can reach temperatures higher than you can with a magnifying glass.

I guess I'm curious: all the comments I see about this act as if the people proposing putting data centers in space are complete idiots. Do you believe they are complete idiots?

  • They're hucksters who know that adding "in space!" to a sales pitch is a free booster for tech enthusiasts.

    It's the same way that Sam Altman talks about the risks of AI deciding to kill humanity: because that's dramatic and attention grabbing, and also the most unlikely outcome. Talking about it keeps us from talking about the real, ground level problems like the massive, unplanned-for disruption in jobs and education.

    They just need to keep the money tap flowing, and tomorrow can worry about itself. Who's going to hold them accountable for data-centres-in-space five years from now, when they don't exist? Has Musk suffered any blowback from his hyping the Hyperloop that never materialized?

  • If they’re actually serious about this, they could simply address the points about cooling that numerous experts have raised. But they haven’t done that, at least not that I’ve seen. I have no idea whether they’re complete idiots, and I don’t really care. Maybe it’s idiocy, maybe it’s hubris, maybe it’s a grift, I have no idea. But until I see a compelling solution to this known problem, or a compelling suggestion as to why they’re not sharing a solution, I’ll continue to think they aren’t particularly smart or serious about this.
