Ultimately AI comes from space :) Just wait until Starship starts flying - with its projected $/kg launch costs the placement of solar + GPUs in space would be the cheapest option (10-20kg is 1 GPU, 5 m2 solar and 2 m2 radiator (at 70C radiating away 1.5 KW) - total launch cost would be around paltry $1-2K) .




Are people seriously still on this “datacenter in space” thing? It has been beaten down with hard facts endlessly the past few months.

you see my numbers in my comment. I don't see any numbers in your comment (please don't give any links to the articles whose authors don't understand black body radiation formula and thus reference ISS cooling in datacenter discussion :)

Facts don't matter when Elon's feelings are at stake

I'd really like to see the math on this one. It implies that building wind and solar on Earth is somehow worse than building it in space _and_ moving the data center there? It's not just counter-intuitive, it's bonkers.

>It's not just counter-intuitive, it's bonkers.

you need to look at numbers instead of intuition - intuition naturally gets us wrong when we deal with unfamiliar things like space.

A ready 10 ton house will cost $500K-1M to place in a well developed area - the cost of land itself, communications, permits, also delays and unpredictability of process, etc. Add to that yearly taxes. Add tremendous electricity costs in case of the datacenter. And all those costs have and will be growing.

Launching 10 tons on Starship - sub-$1M and that cost will drop down to about $100K-200K.

exactly. Space is cheap and plentiful :)
