Don’t forget the practical ability to dissipate waste heat on top of producing energy. That’s an upper limit to all energy use unless we decide boiling ourselves is fine, or find a way to successfully ignore thermodynamics, as you say.

We can always build a sunshade in the Earth-Sun L1. Make it a Sun facing PV panel pointing radiators away from us and we can power a lot of compute there (useful life might be limited, but compute modules can be recycled and replaced, and nothing needs to be launched from Earth in this case).
