I can't read the article, but I'm wondering if the statement is true.
The energy required for those days-centers doesn't change depending on being in space.
In space this power can be generated by solar panels, but we can also do that on earth.
Datacenters need to be cooled, this is easy on earth, but hard in space. Datacenters in space would need massive radiators to make sure the generated heat doesn't build up.
Then ofcourse you need a lot of energy to get it up to space, and again every time you need to do maintenance.
Can anybody who has access to this article enlighten me what their solution is to those issues that would make it more efficient?
