| > the only cooling option is radiative. It does say he's planning an AI sun, I'm guessing that's the temperature you need to run at for radiation to work. |

| There are already large communication satellites that consume several kW of power. |

| ▲ | pantalaimon 6 hours ago | parent [-] | | The data center would still consist of many individual satellites, much like a earth based data center consists of many individual servers | | |
| ▲ | Bootvis 6 hours ago | parent | next [-] | | A large telecommunications satellite operates at about 15kW. A Blackwell GPU consumes 1kW so you would be at 15 Blackwells per satellite. The cooling surface needs to scale linearly so there is little return to scale. This doesn't sound like a good idea to me. | |
| ▲ | esskay 5 hours ago | parent | prev [-] | | tbh you could just combine them with starlink sats. didn't they just apply for (and get?) a license for 1 million sats? Stick a single racks worth of gpu power on those and hey presto you've just got yourself the largest ai cluster in the world by far. |

| > It does say he's planning an AI sun Everything I've heard from Musk in the past decade has been against my will and has made me dumber. (no I do not care to verify or know whether the above is true) Edit: ah fuck ya got me "the next book in SpaceX and xAI's mission: scaling to make a sentient sun to understand the Universe" what the cultish bullshit is this. In a just world investors would be fleeing in droves from this cuckoo behavior (I know xAI & SpaceX are private) |
