I would wonder if solar plus the absolute massive battery reserves you’d need for a data center ten times bigger than the current worlds largest would still be cost effective versus a single fusion reactor

[jay_kyburz]

I wonder how that cost would compare to putting your solar and data center in space? (with non stop solar pointed at the sun)

I wonder if cooling is easier or harder in space?

It's harder. You can stop wondering.

It gets easier if you run things hotter, up to the point that there isn't much of a difference at a few hundred °C (and keeps making no difference when hotter).

Harder. Vacuum is an excellent thermal insulator.

Can’t dissipate heat effectively in space

The Thermos is properly known as a "vacuum flask" (or Dewar flask).
