I’ve been to datacenters, but not the huuuge ones people seem to talk about in the context of AI. They are noisy inside (due to air cooling, which is largely avoided by the tech in the OP), but they’re entirely unremarkable outside compared to any other commercial or industrial building. Computers are not inherently loud, nor is power conversion.

Power plants are all over, even in populated areas. They’re not so bad either (except perhaps coal).

There is no fundamental reason that datacenters need to be especially unpleasant to their neighbors.

On-site natural gas turbines at a handful of DCs are genuinely loud. In general I agree that DCs are mostly fine neighbors, but maybe louder power plants aren't.

It's like anything else in this world. Corner cutting and being shitty leads to shitty outcomes

Sure there is, being a good neighbor costs more than being a bad neighbor

It depends a lot on things like geology and some people are a lot more sensitive. It is really an issue.

I don't have any datacenters near me but I can hear some heavy hums from the washing machine 3 floors up when it put my head on my pillow, for some reason it just propagates through the building physically. When I walk around I don't hear it. Datacenter noise can be the same.

IMO they should be put away from habitation, there's no reason for them to be near there anyway

Right. Vibration propagates through solid (and liquid) materials.

But this can all be measured and controlled, and there's nothing special about datacenters. A building that is hundreds of feet away will couple to your pillow much less strongly than a washing machine in your building. And the washing machine often has a wildly unbalanced load and minimal decoupling between itself and the floor, whereas a big fan in a datacenter or other industrial building ought to be balanced and also ought to be installed on decoupling mounts.

If datacenter operators (cough xAI) are being lazy about properly selecting, installing and maintaining equipment, then you can have a problem. Otherwise you have a much smaller problem.

I agree, but that's a hard problem (in the US anyway). Unless you're plopping data centers in the middle of national parks, or in the middle of the desert where water is going to be a problem, you are nearly always going to be within some small mile radius of civilization. Plus the cost of trenching new fiber out in the middle of nowhere.

The same reasons humans want to concentrate in a particular area (access to jobs, infrastructure) are the same things that data centers need.

Once water-less cooling tech like this improves then yeah, just plopping them in the middle of the unpopulated desert becomes viable (assuming you can get the fiber out there and latency is tolerable), so long as they generate their own power.

The climate requirements to run at this hotter temperature still probably means it'll require more active cooling in the desert during daytime /summers. Assuming we're talking about hotter desert environments like US southwest. That might make your proposal not as economical.

Imo we should just solve the problems with data centers being near cities. Manage/regulate the noise and any waste (heat included, it shouldn't drastically impact the neighbors) and make them pay for any utility capacity/reliability upgrades needed. If this article is right and water usage can be nearly eliminated then it seems like the rest should be solvable? Especially if we can take the extra heat and use it for local power or heating needs.

You might (but probably not) be able to do district heating with this, but electricity generation is not going to be efficient. Heat is a very low grade form of energy, and you need a large differential to drive a turbine efficiently.

If you cycle between 45 C and 55 C water temperature (as mentioned by the press release), you are only getting a 10 C delta. That isn't even enough for district heating, probably not even with heat pumps.

Now if you have something like a steel foundry, that have much hotter cooling water, you can absolutely use the heat for district heating, but even then it usually isn't enough for cost effective electricity generation. Even when it is waste heat, as the equipment to handle it still costs money and requires maintenance.

People said this about high voltage electric lines and wind turbines. Blind tests proved they were imagining things.
