What does space give us that Earth does not in this scenario? Free real estate? They only mention falling costs for deployment.

There's an answer in their whitepaper[0] - see Table 1. tl;dr - power is continuous and free via solar array

> power is continuous and free via solar array
It’s is on earth as well using solar and batteries. What is likely to get cheaper faster? Solar and batteries? Or lifting datacenters to space? The world is almost at the point of deploying 1TW/year of solar, and batteries are catching up. No space required. There aren't a lot of VC investment opportunities speeding the rate of solar and battery deployments though.
The argument probably is that battery advances require not yet existing tech via new chemistry etc while what they are proposing is basically just integrating tech that already exists

Just spitballing here, but what if you built it on Earth, and then used the savings to build a second one on the opposite side of Earth? Now you have equivalently continuous power via solar array and also, as a bonus, air.
Not continuous because weather is a thing. Also the sun isnt directly overhead the entire time so need a much larger array

Free in the sense of astronomical capital and operational costs.
r&d sure, not sure about ops as you can probably just detach a faulty module and launch a replacement.

Power in needs to equal heat out, and that isn't easy in space. They, deceptively, claim that their novel solution is radiative cooling. Relying on radiation for cooling in space is the problem statement! Convective (as on Earth) is significantly more effective.
I'm not one of those idiots who would claim that "we should focus on terrestrial problems instead of space," but this idea seems to have only downsides.

It's kind of depressing that the only way to make this tech better is to feed it more energy. (And apparently now to send it to space)
It's also interesting that everyone is convinced the same capabilities can't be realized with drastically less compute.

Can you please not post comments like this? Thoughtful criticism is welcome, of course, but this sort of thing isn't. Besides breaking the site guidelines, it takes threads in less interesting directions and evokes even worse comments from others. We're trying to avoid that here.

Really, on second look, snark still feels justified here. The issue is with TFA. There is little room for a thoughtful comment in response to something transparent.
Some type of submissions will invariably not result in very deep discussion, when the topic itself is so shallow.

Tbh your moderation is normally very restrained and even handed so was a bit surprising to see you take down several borderline overly snarky comments in a row (that just so happen to be directed against VC investors or YC founders).

I do wonder about data centers in the arctic. Cut out the middle step of greenhouse gases and melt the polar caps directly.
Not to mention the benefit of directly harming extremely vulnerable ecosystems! Win-win

Can you please make your substantive points thoughtfully, without snark or putdowns?
