... but don't send any data centers in space where you will have to dump your heat directly by thermal radiation towards the cold CMB... /s

How do you dissipate so much heat in vacuum? Datacenters will need to boil something like water and then dump it somewhere.

Just like satellites do: heat pipes and radiators.

Not that space DCs are a good idea™ or economical otherwise.

Economics are not the main concern if nobody wants them on Earth.

Water usage is often a red herring compared to how much power, noise, and pollution a gigascale DC uses/creates.

Weird comment on an article where that literally isn’t the case.

I can’t tell if it’s just bot-driven nonsense, not reading the text, or just dishonesty masquerading as commentary.

Do you think data centers and the average satellite generate an equivalent amount of heat?

I had some questions in my mind about DCs using closed loop systems and read the article a little. In case anyone else also has similar thoughts: —- The company said its water consumption was so high last year because of temporary construction-related activities, such as concrete work, dust control and site preparation. Once operational, the company said the data centers only will use water for domestic needs, such a…

Will is doing a lot of heavy lifting in this paragraph.

Sats are optimized for low energy usage. DCs, on the other hand, are water boilers.

Do you have anything constructive or non ad hominem to say?

I think you should apologize for being a complete asshat.

I'm sure that's the plan; I'm also sure a MBA will suddenly be in charge of operations and compare their cooling bills with their water bills and conclude it's cheaper to just pump water than run the cooling units.

From about 5 minutes of digging, I found the below which perhaps helps to put the 29m gallons in context.

> The Fayette County Water System has a total production capacity of 22.8 million gallons per day (MGD).

Source: hhttps://fayettega.org/doing-business/global-access-infrastru...

So...keeping things simple and using months of 30 days:

Using 29M gallons over 15 months = 29,000,000 / (15 * 30) = 64,444 gallons per day avg

Based on 22.8m daily production capacity that's less than 0.3% of the total production capacity per day.

(Happy to be corrected if my napkin maths is wrong / i'm missing something here!)

This industry line about closed loop systems not using much water is so pervasive on HN and so wrong. So many people are spreading industry propaganda

First of all, only about 10% of data centers use closed-loop systems. Pointing to a technology that technically exists but is far from standard to represent the entire industry is ridiculous.

Second of all, these facilities do NOT infinitely recycle water. They must regularly "bleed the lines" to remove toxic sludge. The build-up of PFAS is of particular concern. Not to mention the water itself needs to be treated with anti-freezes, anti-fungals, and anticorrosives in order to last multiple cycles.

They also require about 40% more electricity usage. So the trade off is about 70% less water for 40% more electricity and an extremely toxic sludge problem.

TL;DR: closed loop systems are a tiny minority of DCs and their net benefits over open loop are not even clear
