My draft blog post about all the things that are up with space data centres keeps getting bigger and bigger. "The other half of the MS model is data centres. “Orbital compute deployments” start in 2028, reach cost parity with their earthbound equivalents by 2031, and put 364GW of rigs in space by 2040." With 25% efficient cells, at 500 km altitude, in a terminator-tracing SSO, this is enough to occupy a *contiguous*…
He3 is needed as a cryogenic for quantum systems, not fusion fuel.

> Starship is going to be huge when it's finally operational. Any day now. Yep, real soon, honest!
Don't repeat mistakes of people that were making fun of SpaceX landing rockets before they started to land. Starship has so much innovation in there, the raptors itself etc. It launches, it flies, it re-enters and it lands. The engines work. The heat protection work. Even when they push it to the limits by intentionally experimenting with different heat protection, omitting tiles etc. Even when they are in R&D stage.…

I just skimmed that linked paper. Only mention I found of cooling is: > Cooling would be achieved through a thermal sys- tem of heat pipes and radiators while operating at nominal temperatures. Isn't that drastically underselling potentially one of the harder parts of this whole endeavor?
Very drastically, the ISS solar panels can generate up to 120kW of power, look at the size of its radiators needed to cool it down. Scaling that to the hundreds of GW range is quite laughable.
While I'd suspect the design is still in flux, the current design is for a 120kw satellite with 110 square meters of radiators. Scaling to hundreds of gigawatts is intended to be by repeatedly launching smaller designs.

There just isn't that much demand for space. Space is cool to nerds like me, but what do I really need from it? I've got all the navigation satellites I could want (which I don't pay for) and the best satellite imagery I use is still hyperspectral airborne imagery. Now, of course that's not the full story but the use cases get rather specific beyond that: the launch market just isn't actually very big (afaik $30 bill…
Without doing a google search - optical fibers factories and pharma factories can deliver higher quality products when built in space. And I bet there are hundreds of other examples. Just because launch costs were high and these weren't viable before, doesn't mean they won't be viable now.
Those seem like classic examples of what you get when you have a solution in search of problems.
What’s the monetary value of the incremental improvements in those products, and how does it compare to the cost of setting up and operating manufacturing facilities in orbit?

Starship is going to be huge when it's finally operational. It seems like it should be worth more than $8/shr if the potential is accounted properly.

China and other competitors have other ideas, even if you're not aware of them. When your whole pitch is that you're commoditising a technology, don't be surprised when you get a commoditised market.
Their lead is insurmountable, might bleed 1/2% to china but they own launch market and will do for the next century.
China is going to eat them, just like they ate Teslas insurmountable lead in a few short years.

#49This feels like the “there’s a global market for maybe 4 computers” of the 21st century.

The whole AI/orbital datacentres/launch thing is a giant grift.
