> In the right orbit, a solar panel can be up to 8 times more productive than on earth, and produce power nearly continuously, reducing the need for batteries.

Sure. Now do cooling. That this isn't in the "key challenges" section makes this pretty non-serious.

A surprising amount of the ISS is dedicated to this, and they aren't running a GPU farm. https://en.wikipedia.org/wiki/External_Active_Thermal_Contro...

How much are you ready to bet against Elon's plans to scale up Starlink v3 for GPUs? Starlink v3 already has a 60M length solar array, so they're already solving dissipation for that size. Assume linear scaling to many thousands of modules.

From https://x.com/elonmusk/status/1984249048107508061:

"Simply scaling up Starlink V3 satellites, which have high speed laser links would work. SpaceX will be doing this."

From https://x.com/elonmusk/status/1984868748378157312:

"Starship could deliver 100GW/year to high Earth orbit within 4 to 5 years if we can solve the other parts of the equation. 100TW/year is possible from a lunar base producing solar-powered AI satellites locally and accelerating them to escape velocity with a mass driver."

I'm sure they'll be ready right after the androids and the robotaxi and the autonomous LA-NYC summoning.

Starlink v3 doesn't exist yet. They're renders at this point. Full-sized v2s haven't even flown yet, just mass simulators.

I love your enthusiasm

Please post where you are creating the bet. You should make a lot of money from it

Betting on "Elon misses a timeline" or "Elon waters down previous plans" is tough, because no one wants to take the other side. It's guaranteed.

Spacex turns the impossible into the late. Been a shareholder since 2008

You didn’t say it would be late, you said it’s impossible. Setup the bet sir

Perhaps you could reflect back on whether you were saying anything at all

You’re obviously intelligent. You could have bigger impact if you had the courage to be less cynical

Sure. AI datacenters IN SPAAAAAAAACE probably fall in the same vaporware category a good portion of Musk claims fall into. More DOGE/Hyperloop than Falcon 9/Tesla.

Impossible? No. Probable? Also no.
