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.

Orbital data centers are a dumb idea. Put a solar farm in the desert and add some batteries? That’s cheaper.So I wouldn’t be too worried about this, the economics of this won’t pan out.

With today's very high orbital launch costs, it's trivially true that the desert is cheaper.With very low orbital launch costs, it's trivially true that space would become cheaper. Solar panels have no atmosphere/night/seasons and are always pointed at the Sun, no cover glass for hail, no 24h battery either. Radiators are 1/10th the area of PV which is very doable.
The question is, where exactly is the tipping point between those two extremes, and will Starship reach that? Opinions on this naturally bifurcate depending on one's feelings about Elon Musk.
I wouldn't be too worried because SpaceX engineers put a great deal of effort into reflection mitigation, including developing a space-rated mirror able to have an RF signal fire transparently through it.[1] The strategy is to bounce all the sunlight away from Earth, which makes satellites darker than even (hypothetically) covering a satellite in Vantablack.

I don’t want to be foolishly dismissive, but I just don’t see how launch costs could be small enough to compensate for the huge overhead of putting things into space and maintaining things in space as opposed to literally any other place on earth.I think the burden of proof is on the people who want to tell us that this is economical to show the numbers

Ok I’ll try:Starship becomes “fully and rapidly reusable”, needing little to no refurbishment between launches. Then the lower bound of launch costs is just the expendables (methane, oxygen, nitrogen) which could cost as little as $1M per launch.
SpaceX uses custom silicon (produced by “TeraFab”) that can run at higher temperatures then the radiative cooling requirements goes down significantly and a 100 kW satellite might weight around 1 ton.
Starship should be able to launch at least 100T payload. Assuming they could fit that many, that puts the launch cost per 100 kW at $10,000, which is a rounding error compared to the cost of the chips alone, even if it’s off by a factor of 10.
Obviously a lot needs to go right for this to happen, but it’s not impossible.

Counter argument:Before the cost of flying very heavy shit and dealing with all the problems of operating that shit in space goes to zero, the cost of doing it terrestrially will go to zero. The idea that shooting any amount of payload into space could some how be more economical than just not doing that is completely bonkers and laughable.
It's like people completely forgot that there was 15+ years of connectivity infrastructure build out on earth before Musk did his shittier space version, not the other way around.

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.

A desert isn’t necessarily hot.by lostlogin
4/1/2026 at 4:30:48 PM
It's actually very easy to cool in deserts, because low humidity makes it very easy to move heat into the ambient air. You have to contend against ambient temperatures, but that's what insulation is for. The other big things you need for datacenters are reliable power and a low probability of infrastructure-disrupting natural disasters.by cheald

You can do radiative cooling in space (you just need big radiators). You cannot do that reasonably in desert.by zajio1am
4/1/2026 at 12:36:03 PM
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.by m4rtink
4/1/2026 at 1:51:02 PM
I did realize geothermal would be the way to do it in the desert; the ground is still typically cooler than the heat computers give off.It's still problematic that most deserts dont haveaccess to groundwater, so bootstraping and maintenance are an issue.
by cyanydeez
4/1/2026 at 12:59:05 PM
You can try to put the heat underground. Maybe there is an aquifer you can use. Or maybe your desert is close to the coast!Still easier than radiating it into space.

Is throwing up "1 million satellites" going to do those things?How about running DOGE and gutting USAID?

Exactly. Nobody can defend fraud and abuse. Since your main issue is that the savings weren't as big as expected it sounds like you know that.

Getting Russia out of the Ukraine.

No. Russians have tried to use Starlink in late 2023 early 2024, there were no direct or indirect sales and terminals were disabled on a blacklist basis. They moved from a blacklist to a whitelist in February this year.
> This administration is anti-fraud and anti-abuse
In some ways, yes. I won't defend "Trump coin" but it's pretty clear with things like USAID, Minnesota child care center scams, and the California hospice scam the democrats were in favour of and participated in fraud and abuse.

When did he do this? Are you referring to (LOL) DOGE? Nothing like raising unemployment without saving any money:

And let's not start on all the illegal actions:

Those (supposed) efficiency cuts in (e.g.) USAID have been estimated to have caused many tens of thousands of deaths:

And how much of the (alleged) money that was saved is now going towards the Iran war? The Pentagon is asking for $200B:

> There are more things to life than the price of gas.
That is a very privileged view. In the US specifically, with its abysmal public transportation due to car-centric {ex,sub}urban design, a lot of people will need to pay more for getting to work and will have to cut back on (e.g.) groceries.
Globally, oil prices are wreaking havoc in all sorts of ways on daily life:
> Worsening fuel shortages resulting from the war in the Middle East are threatening sacred funeral ceremonies in Thailand, where Buddhist temples are scrambling to obtain diesel for cremations.
> The abbot of Wat Saman Rattanaram in Chachoengsao province, about 80km (50 miles) east of Bangkok, warned that a suspension of cremation services was a real possibility. Some petrol stations have run out of fuel, while others allow sales only to vehicle operators.

Yes.

Your source at Cato Institute confirm 150B.

Lancet is a political advocacy magazine. USAID isn' an AID agency. Not funding gay and lesbian theatre in Serbia doesn't stop anyone from dying.
> much of the (alleged) money that was saved
You said zero money was saved earlier. What is it?

It seems like a better investment than giving Iran 1.6 billion dollars to fund terrorism across the middle east, wouldn't you say?
