Still has to radiate... and there's material and surface area limits.

Which improve greatly if you can evaporate a material along the way...

What's the thoughts on modelling the Stirling as if it were a sort-of
reverse fuel cell? Instead of combining H2 and O2 to get power, it
loses H20 at the same mass/volume rate to dump heat?

Just come up once a week in the Type-S and run a hose from a tank in
the cargo bay...
