To put into perspective, each satellite that could only accommodate, at most, 2-3 servers would have a power and cooling burden greater than the entire international space station. For each 2-3 server unit, you have an ISS-magnitude power and cooling challenge. They would be looking to have hundreds of thousands of ISS-scale satellites in orbit....

Ya, the economies of how much total space / material for the global network is similar, although lets say higher due to losses in efficiency in distributing it over so many dishes, but in terms of how big any individual radiator is and how much space each one is going to take, the smaller sizes make it easier to manage. Trying to figure out a 150-200m^2^ solar panel radiator is a lot easier than trying to figure out a 1km^2^

The individual power of each satellite having to use a mesh network to train might not be fast enough, maybe they'll still use land based ones for training, but no single person needs more compute than what a satellite can provide. So from the inference / customer computation side of things, it isn't a problem.

edit: I meant radiator, not solar panel

edit: looks like blackwells can run sunstained at 88c, so that will help a bit more as well on size, the calculator now says 103m^2^ instead of 127m^2
