So many questions, like how would you protect from bit flips, damage to circuits. "10x lower energy costs and reduce the need for energy consumption on Earth." I am not sure if we need a rocket scientist to calculate the energy costs of manufacturing and sending a rocket to outer space versus putting that fuel into a generator and just letting it run. What happens when the servers need to retire due to some unpatchable bug

I believe it's on the order of magnitude of 100x return (for a low-orbit space photovoltiac panel that's (almost) always facing direct sun).

    (/ (* ([W (kg -1)] 200)   ;; reasonable space PV power/mass ratio
          ([year] 10)         ;; guess at lifespan
          ([ton] 100))        ;; Starship payload
       (* ([ton] 1000)        ;; tons of liquid methane in Starsihp
          ([J (kg -1)] 5e7))) ;; specific energy density of CH₄
    
    ;; => 126.226944

Yeah, radiation is the enemy of integrated circuits, cosmic radiation is more damaging the smaller the features get.

You pretty much have to have multiple redundancy and special space-rated HW, which I wouldn't be surprised is stuck at super old process nodes to mitigate this exact same issue.

Tbf, leaving aside the claims about datacentres in space, working with Nvidia on radiation hardening its latest generation chips would be a good project...
