We currently make around 1 TW of photovoltaic cells per year, globally. The proposal here is to launch that much to space every 9 hours, complete with attached computers, continuously, from the moon.
edit: Also, this would capture a very trivial percentage of the Sun's power. A few trillionths per year.
Orbit gets you the advantage of 1/5th the PV and no large daily smoothing battery, but also no on-site installation cost, no grid interconnect fees, no custom engineering drawings, no environmental permitting fees, no grid of concrete footers, no heavy steel frames to resist wind and snow loads. The "on-site installation" is just the panels unfolding, and during launch they're compact so the support structure can be relatively lightweight.
When you cost building the datacenter alone, it's cheaper on earth. When you cost building the solar + batteries + datacenter, it (can be) cheaper in space, if you build it right and have cheap orbital launch.
Besides making PV much more consistent, the main thing this seems to avoid is just the red tape around developing at huge scale, and basically being totally sovereign, which seems like it might be more important as tensions around this stuff ramp up. There’s clearly a backlash brewing against terrestrial data centers driving up utility bills, at least on the East Coast of the US.
The more I think about it, the more this seems like maybe not a terrible idea.
Like this argument just gets absurd: you're claiming building a data center on earth will be harder from a permitting perspective than FAA flight approval for multiple heavy lift rocket launch and landing cycles.
Mining companies routinely open and close enormous surface area mines all over the world and manage permitting for that just fine.
There's plenty of land no one will care if your build anything on, and being remote with maybe poor access roads is still going to be enormously cheaper then launching a state of the art heavy lift rocket which doesn't actually exist yet.
And permitting is challenging in part because it’s so different from place to place. Their permitting process with the FAA seems pretty streamlined.
Right? So if that's the case why would putting them in Space, far less accessible in every conceivable way, with numerous additional expenses and engineering constraints, be cheaper?
Maybe there's a concentration in VA because there's a set of deals/procedures in place with infra providers there that make it easy to scale up, similar to how DE has well developed corporate infrastructure, so everyone incorporates there. But that stops when the area hits its limit in power provision (which seems to be happening right now). In which case, being able to do this yourself end to end by putting this stuff in space with your own power generation makes it the ultimate scale-up opportunity - no real limits on space or power availability, so once you get that method down, you can mass-scale and get great economies of scale. Maintenance isn't a thing, these will be disposable.
I think that's it, money's not the limiting factor if they can pitch this successfully, which I think they will. They want massive scale without the constraints you hit when doing it on earth. I think he's aiming for scale that we haven't seen in DCs on earth.
