A former NASA engineer with a PhD in space electronics who later worked at Google for 10 years wrote an article about why datacenters in space are very technically challenging:

I don't have any specialized knowledge of the physics but I saw an article suggesting the real reason for the push to build them in space is to hedge against political pushback preventing construction on Earth.

I can't find the original article but here is one about datacenter pushback:

But even if political pushback on Earth is the real reason, it still seems datacenters in space are extremely technically challenging/impossible to build.

"Technically challenging", a nice way to say "impossible"

>>edhela+Mt
Just like rockets landing themselves

>>boxede+Yy
No, rockets landing themselves is just controlling the mechanism you use to have them take off, and builds on trust vectoring technology from 1970s jet fighters based on sound physics.

Figuring out how to radiate a lot of waste heat into a vacuum is fighting physics. Ordinarily we use a void on earth as a very effective _insulator_ to keep our hot drinks hot.

>>sollew+WB
His point is that everyone said landing and reusing rockets was impossible and made fun of Elon and SpaceX for years for attempting it.

>>fourse+hE
He also said he could save the us a trillion dollars per year with DOGE, and basically just caused a lot data exfiltration and killed hundreds of thousands of people, without saving any money at all

>>Smirki+SK
Elon Musk killed hundreds of thousands of people?

>>sejje+3V
Yes. Mostly kids, because of the DOGE ransacking of USAID
