AI data-centers use upwards of 100MW. The biggest solar panels in space could produce around 240KW. When they speak of AI data-centers in space what do they actually mean in realistic non theoretical terms and where are the materials for this coming from?

If the AI data-center used only 10MW then each could have two redundant SMR's assuming the cooling challenges have been worked out but then we could have nuclear reactor disposal and collision issues.

I assume the idea is to have the entire constellation be the data center in question. Laser back haul transceiver bandwidth is in the same order of magnitude of rack-to-rack bandwidths [1][2]. I could see each sat being a rack and the entire mesh being a cluster.

For AI training, latency is one of the limiting factors, which needs to be kept in the nanoseconds. And a light-nanosecond is famously almost exactly 1 foot.

That's why Lumen/Starcloud's designs all assume it'll be a space station with all containers connected to one central networking spine.
