The SpaceX AI1 Satellite is awesome! I love it!
$SPCX
BUT to put things in perspective, relative to a land-based data center:
- A 120 kW compute payload = 1/2 a Rack
- Today's 1 GW DCs have ~4,000 racks at 250 kW
- You would need 8,000 AI1 Satellites for 1 Data Center
- IF Starship (which has never flown successfully yet) could take 80 AI1 satellites up at a time (it can't), it would take 100 Starship launches for equivalent of 1 Data Center!
- IF Starship launches cost just $100 Million each (Falcon 9 costs ~$60 Million), that would mean $10 Billion for JUST the launch cost, not counting the actual hardware (solar/chips/cooling/etc.)
- These 8,000 Satellites would have MASSIVE communication delays relative to a data center with 4,000 racks sitting next to each other with high-speed fiber communication between the racks.
I was more optimistic about space-based data centers, but if AI1 is the state-of-the-art of what we might have in say 2-3 years (optimistic since this is Elon time we're talking about), even those numbers pale in comparison to a land-based Data Center!
Sigh.
