1. It's cheaper to make a vacuum on earth around a computer than it is to send a computer into space.

2. That would also presumably work on earth, unless it somehow relied on low-gravity, and would also be cheaper to benefit from on earth.

That’s not what 1 is about.

The problem for 1 is how do you dissipate heat without being in contact with a lower temperature mass.

Creating a vacuum on earth would solve nothing as the heath would still have to escape the vacuum.
