Eric Schmidt Apparently Bought Relativity Space To Put Data Centers in Orbit (arstechnica.com)

(Friday May 02, 2025 @05:20PM (msmash) from the sky's-the-limit dept.)


An anonymous reader [1]shares a report :

> In the nearly two months since former Google chief executive Eric Schmidt acquired Relativity Space, the billionaire has not said much publicly about his plans for the launch company. However, his intentions for Relativity now appear to be increasingly clear: He wants to have the capability to launch a significant amount of computing infrastructure into space.

>

> We know this because Schmidt appeared before the House Committee on Energy and Commerce during a hearing in April, speaking on the future of AI and US competitiveness. Among the topics raised then was the need for more electricity -- both renewable and non-renewable -- to power data centers that will facilitate the computing needs for AI development and applications. Schmidt noted that an average nuclear power plant in the United States generates 1 gigawatt of power.

>

> "People are planning 10 gigawatt data centers," Schmidt said. "Gives you a sense of how big this crisis is. Many people think that the energy demand for our industry will go from 3 percent to 99 percent of total generation. One of the estimates that I think is most likely is that data centers will require an additional 29 gigawatts of power by 2027, and 67 more gigawatts by 2030. These things are industrial at a scale that I have never seen in my life."

The largest power supply in space is the ISS solar panel array, supplying around 100 kilowatt, only ten millionths of the 10 gigawatt data centre quoted in the article. Even so, the panels are the size of a football field. So yeah, good luck with that.

Even assuming the energy demands are met somehow, all that energy eventually would turn into heat which would need to be dissipated away.

In orbit, having to rely only on radioactive heat transfer instead of much more efficient conduction/convection, dissipating enough of that heat away to keep the datacenter's temperature within reasonable limits would be completely unrealistic.

Negative, although I approve of your pedantry. In terms of instantaneous radiated power, the largest power supply in space is a black hole collision. The largest observed so far was also the first, named GW150914. It radiated over 10^49 watts, temporarily exceeding the output of the rest of observable universe.

Why you'd want to put all those computers into space, OTOH, is beyond me. The solar power available in space is strong and continuous, sure, but the costs of getting the equipment up there and keeping it serviced and running are so high that just about any kind of ground-based power would be orders of magnitude cheaper.

Just from a technology perspective, are there any of the bleeding-edge chip processes that yield radiation-hardened parts, or parts that take the kind of vibration that goes with launch to orbit?

Quite the crisis they've manufactured there. Maybe we just don't need this sort of pervasive AI that these guys envision. Actually they envision the money coming in. The technology itself is just a vehicle. The older I get the more in favor I am of the Butlerian Jihad.

AI is a fantastic tool, but given the choice between having clean water and electricity, or AI, I'd prefer meeting humanity's basic needs.Plus a little work and actual creativity never hurt anyone.

First of all, with all the space debris, unless one sticks the data center way up there, it is likely to get perforated by space debris, especially when Kessler Syndrome hits.

Fortunately the two problems with the scheme cancel perfectly. There is no way to generate even megawatts in space, and there is no way to dissipate megawatts in space, for any practical space station size in the foreseeable future.

Both the production of that much electricity and the consumption of that much electrical power has to generate a shitload of heat. I guess a data center in space would not have quite the same cooling problems as one on Earth. BUT that would require careful design to make sure the heat radiates off the back of the solar panels.

Cooling fins don't work in vacuum.

Cooling in space is hard. Harder than on Earth because you don't have an atmosphere, so even though space isn't hot, it's not cold either. It's more like a huge insulator. So, for an example, you have a 10GW nuclear reactor generating power, you need to cool it before we even begin talking about the datacenter it will be powering.

How do you emit any serious part of that 10GW out of the space datacenter? The mechanism we h

How does one move heat? There are three ways. Conduction, but there is nothing touching the heat source in orbit so that won't work. Convection to a fluid. Oops, space is a vacuum, no fluids.

That leaves radiation. That will work, but "Stefan-Boltzmann law, states that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature."

How hot can you get these chips again? I didn't think so.

Sure. It's expensive, but if you have enough solar panels and the right orbit, you have eternal power for free after the initial investment.

What you don't have is easy cooling, nor low data latency. And you have to deal with high energy radiation.

Out of all the issues, the cooling issue is probably the largest obstacle. The idea of a real datacenter in orbit is just stupid.
