So, the AP believes that 166.9/150 == 1.24. Guess again, guys.
OK, innumaracy raises its loathsome head. But with the /AP/?
(I get 166.9/150 == 1.11; interestingly, 24% of 150 is 36, not 16.9 --
so I don't want to hear about how I am misundertanding their
statement.)
Of course, since this is all "funny money" anyway, it doesn't really
matter. If the share price dropped to, say $83, Musk would be a half-trillionaire immediately.

This is interesting: it suggests that businesses feeding each other in >circular fashion is responsible for much of this hype. It also suggests
that SpaceX is being used as a fig-leaf for Musk's Grok AI plans.
Musk has announced some plans for putting "AI data centers" in space which seems like a terrible idea to me since your problems of getting rid of heat become that much worse.

I wish the many people repeating this would explain the problem to
me.
You have a body that orbits (the Earth which orbits) the Sun at the
Earth-Sun distance. This body is heated by the solar illumination
is receives and cooled by radiation against the background of space.
At that distance from the Sun, the average temperature of such a
body will be similar to that of Earth. Whether it's a proposed AI
satellite, any of countless existing satellites, or a dumb rock.
Where is the extra heat coming from that getting rid of is supposed
to be the problem? The satellite converts some of the incoming
light photovoltaically intro electricity which it uses to perform
work, but that doesn't change the heat balance.
You can question the _economics_ of the proposal, but that is
a different issue. Musk put up a video where he is discussing
his ideas:
https://x.com/SpaceX/status/2064099405758906727
I couldn't be bother to sit through half an hour of talk, but
from what I glimpsed, his thinking appears to be:
* We want/need so much AI that running it would take a significant
part or even more than the electrical power that is available
in existing or near future terrestrial grids.
* Economy of scale will make this cost-effective if we just scale
it up enough.

The computers that do the AI generate heat, just like the computers on
the ground generate heat. If I remember right, the ISS has issues with
extra heat at times.
I'm just guessing but the heat problem is that all of the power from the incoming photons is concentrated into a small area, and the small area
heats up. That heat must be radiated away.

Presumably the ISS has problems with _distributing_ the heat. In
particular, there is no convection in zero g, so you have to be
very careful with inside equipment designed for Earth conditions,
because it can develop hot spots. You need forced cooling, i.e.,
a fan.

Yes, you need a cooling circuit to distribute the heat. But I fail
to see how the absolute amount of heat to be dumped is a problem.

Yes. The _only_ cooling you get is by radiation. Cooling by radiation
is only useful for very hot objects... you don't get convection cooling
in space.

Well, that's the OTHER half of the problem. Where IS all the energy to
run those computer systems going to be coming from? You have a couple >megawatts of electricity going in and a couple megawatts of heat coming
out and both ends of that are problematic.
Musk says:
* We want/need so much AI that running it would take a significant
part or even more than the electrical power that is available
in existing or near future terrestrial grids.
* Economy of scale will make this cost-effective if we just scale
it up enough.
If we can't get that much electrical power on earth, how are we going to
get it in space? Nuclear power is feasible but that's only half the >equation.
I can't help but think that the solution for all of this mess lies in
more efficient software.
