Still easier to cool in the desert than in space

Lack of medium in space so can't rely on convection or conduction there? This is really basic.

Presumably that vacuum is an insulator.

Datacenters need cooling. Cooling always externalizes heat go the environment. The places you want centers are cold and water available. Neither space or typical deaert.

You can do radiative cooling in space (you just need big radiators). You cannot do that reasonably in desert.

The world seems to have become an abstract plaything for these billionaires why would they give a damn about practicality. This idiot shot a car into space for no good reason.

He can blow his money on 1 million satellites that will all decay back into the atmosphere within a few years

Why should he be allowed to pollute the night sky like that?

One of the most profound feelings I had was being in the middle of nowhere at night and looking at the sky.

Majority of people my generation are able to experience what once was very common only few times in their lifetime due to light pollution.

It feels dreadful to realize that even that experience will be taken away forever.

Decay and be replaced. You make it sound as if this is short term, like flinging confetti up in the air, instead of long term, like tiling a roof.

He can also 'blow' his money on helping people by giving them opportunities:

> In 1993, Harris Rosen “adopted” a run-down, drug-infested section of Orlando called Tangelo Park. Rosen offers free preschool for all children prior to kindergarten and a free college education for high school graduates. Today, the high school graduation rate for Tangelo Park is 100 percent. And no, that is not a typo.

Helping people with ALS speak again seems worthy, as does helping humanity become a multi planetary species.

Taking aside you certainly can do radiative cooling in desert at night just fine - you have air, which even if hot to desert standards during the day is still by magnitudes more effective for cooling via direct heat transfer than radiating heat away in vacuum.

Is throwing up "1 million satellites" going to do those things?

How about running DOGE and gutting USAID?

Or helping Trump get elected? Was that a worthy endeavour? How's that working out for the average American (or anyone else on the planet) with four dollar gas and five dollar diesel?
