Do you imagine there'd be less red tape involved in launching multiple rockets per day carrying heavy payloads?
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.
> Ok, why are so many being built in Northern Virginia, rather than in the middle of nowhere where there will be no backlash?
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?
Yeah, I don't know if it wins on cheaper, even with $2M fully reusable starship launches. Maybe rollout speed vs piecing together BD deals with a bunch of different infra providers? The expansion of the grid is going to be hamstrung until congress finally passes energy permitting reform, which they've tried and failed at repeatedly. But they could do non-interconnected microgrids in the desert like Redwood Materials has been trying.
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.
Just based on weight, looks like a Block 4 starship should be able to bring up ~150 30 panel pallets of 550W panels, about 2 MW. They're trying to get a starship launch down to $2M with full reuse. GPU DCs are frequently in the neighborhood of 500GW, so maybe 250 launches for just the power generation, or $500M? And then there's radiators, so let's say $1B for launch of power and heat dissipation. For comparison, 500MW of H100 machines retails for >$10B, and the launch cost for those shouldn't be too bad compared to the power, since they're more value dense. And then there's land and ongoing power and cooling spending for the terrestrial version, which you don't have for the space version. So actually, doesn't seem terrible economically? This is obviously very back-of-the-envelope, and predicated on the optimistic scenario for starship launch cost.
You cannot just block out the mass of stuff and declare it'll cost exactly the launch cost, nor can you take the cost of current datacenter servers and go "they'll definitely cost the same to put in space".
A regular set of servers will straight up be destroyed if put on a rocket and launched into space: the motherboards and PCBs aren't mounted or rated to survive the vibration. The connectors and wiring isn't rated for that vibration. Sure, some probably make it, but you will lose machines from just launching them alone. Any electrolytic capacitors in there? If your system exposes them to vacuum or even just low pressure, then those likely die too. Solar panels? We can launch them obviously, there's a reason people send up expensive solar panels: because you're doing a lot of work making sure they'll physically survive the launch.
So of course, now you have to build a space-rated server frame, PCBs and GPUs. You ain't going to buying bulk H100's from Nvidia. And you have to package and mount it to get it both survive the launch and physically fit into the payload bay. Then you have to add a deployment system for it, sensors etc. And then you have to add an assembly system, because if it doesn't fit in one launch (you're proposing 250+ launches for power alone) then all of these systems need to be assembled in orbit. How are they going to be assembled? How are they going to be maneuvered? Even if you could rendezvous accurately with the construction orbit, we're talking months of drift from every little thing knocking stuff around, putting it into a spin, etc.
So either each of these is now a fully contained satellite, complete with manoeuvering system and power, or you're also needing to develop a robotic assembly system - with power and manoeuevering in order to manage and assemble all this.
And let's not forget mission control: every single one of these steps is incurring a bunch of labor costs to have people manage it. And not cheap labor costs: you're going from "guys who roll racks in and plug stuff in and can be trained up easily" to "space mission control operators".
Is this doable? Probably. Is this going to be in anyway cheaper then Earth? Not in the slightest, and it's not going to be close.
Heh relax, it’s back of the envelope to try and see if it’s anywhere in the ballpark, and if they get launch to be cheap enough, it seems like it might be. You don’t assemble one massive thing in space, it’s a bunch of disposable individual sats with laser interconnects, like Starlink.
