But it doesn't make any _money_. Approximately all the ballpoint pens in the world are dependent on a single company, Mikron Group. It has a market capitalisation of about CHF 275.5 million. "We're the only ones who do that" is insufficient; it has to make money. And honestly, generally, "we're the only ones who do that" is a strong sign that a thing doesn't really make much money; if it did, well, other people would do it.
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* ring roughly 25 m tall, all the way around that orbit.
Also, from other statements they're clearly copying Alphabet's study which said cost parity in 2035, if they can actually launch 370,000 tons and maintain their learning rate.
"A $668bn funding obligation to 2034 that delivers free cash flow that year of negative $48bn sounds less than ideal, though FCF might flip positive to $138bn in 2035 if everything goes to plan, so that’s nice. The SpaceX CEO presumably has a long history of delivering products on time and to the required specification that can support such confidence."
I love the snark here.
"Helium-3 is one of the clearest examples of why lunar infrastructure could matter. The isotope is extremely rare on Earth, with current supply largely tied to tritium decay, but the Moon has accumulated helium-3 for billions of years because it lacks Earth’s atmosphere and magnetic field. NASA mining concepts often assume concentrations around 20 parts per billion, meaning helium-3 is abundant in total but painfully diffuse, requiring hundreds of tons of regolith to be mined and heated to recover small quantities."
Ugh. This will need a separate blog post for why it's stupid. At 20 ppb, even if we could fuse He3, that makes lunar regolith marginally less energy dense than firewood. Also, anyone with a fusion reactor can make He3, even highschool students with home-made fusors can already do this. I'll have to check sources and maths to make sure I've not missed something important about which would be cheaper, *currently existing* neutron sources like fusors or going to the moon, but regardless, we can't currently use this stuff for fusion and the moment we can we won't need to mine it.
(I have not yet formed an opinion about non-fusion uses for He3).
The cost of fuel is not the problem. We have unlimited uranium and thorium, and there is no reason a fusion should be cheaper. Sure its more dense then fission but fission is absurdly dense already and the economics don't improve that much.
The idea that it makes sense to use moon based He3 compared to using thorium that is already mined in waste quantities is absurd. Thorium is free energy already and the machine that turns it into energy is simpler the any fusion reactor we can come up with.

Ah. There it is. Even if that's all done as investment-grade debt (with a 50 bp underwriting spread), that's $3+ billion of banking fees.

I have a hard time imagining how spx stock will drop to a reasonable price. You have to be a true believer at its current valuation, so who is going to sell? Maybe if enough insiders or stock options start selling it will drop.
Well, as I understand it, SpaceX intends to continue to raise money from the market. Eventually the true believers will stop having money to give them.
I expect via court order or government intervention.
How many of the HODLers will be SpaceX believers, vs. Musk believers? Musk's already only narrowly avoided being banned from running publicly traded companies from the $420 tweet years back.
