This opens up an interesting synergy: district heating. 45C is low but not unworkable for a district heating loop, and a data center might be able to make a nice pitch to a community if the data center offers to provide heat to a district heating system for free. This brings the value to the local community of a nearby datacenter up from near zero to potentially a few million dollars per year. Summer is still an issu…

The data centers can also be used to heat swimming pools [1]. [1]: https://www.bbc.com/news/technology-64939558

Can we also make a jaccuzi? with bubbles? that would be funny.

Waste heat from these things is negligible compared to the sun heat. I know people love to hate on these things, but come on...

Well you know, data centers are optional. The sun is not. What a disingenuous comparison, do you hear yourself?

Comments on the internet are also optional, yet you do it

Blew my mind living in a Berlin apartment, that the heating & hot water was managed centrally for the entire block (not the apartment block, the whole city block). Too used to Anglo cities where everyone does for themselves.

It makes a lot of sense when there is waste heat. But in places where there isn't, having per house or per apartment block heating unit is preferable because you cut on transmission losses and infrastructure cost

As I understand it, it's about economies of scale. It's cheaper to heat enough for the whole block in one big unit than it is to have a couple dozen smaller unit doing their own heating. I haven't really studied it. I'm sure the Germans have, efficiency is a whole cultural value with them ;)

> In the right geography — somewhere with reliably cool outdoor air Aaahh, there’s the catch. “Save resources on cooling by building your data centre somewhere cold, and pollute the surrounding environment by dumping your waste heat wholesale into that!” Good job Nvidia, I almost thought we had something good there.

>the way we heat up the earth right now, i don't think you have to worry about heating Nearly 10x more people die from the cold than from the heat. "...9.43% of global deaths were attributable to non-optimal temperatures, with 8.52% from cold and 0.91% from heat." https://www.thelancet.com/journals/lanplh/article/PIIS2542-5...

This study doesn't factor in droughts, floods, crop death (and starvation), and other non-direct effects. It also doesn't consider wet-bulb events, because it's looking at average ambient temperatures. I don't think this is climate change propaganda, but your application of this study by evoking it in a discussion about climate change feels like it.

Deaths from all natural disasters have dramatically decreased over the last century.

I won't bother sharing the source because you'll find some reason to dismiss it I'm sure.

It's interesting you claim my comment is propaganda when I cite a scientific source and yet have nothing to say about the parent comment which claims we no longer need to worry about heating due to climate change. Which of those comments seems more propagandistic?

It still makes sense. If heat is produced by a burning something, it is is more efficient to do that in one dedicated place. It makes it easier to pipe exhaust away from apartments and efficiency can be higher.

Also gas pipes to every home isn't a thing in many countries.

Have you stopped for a second to consider the utter mathematical absurdity of what you’re suggesting here? It is impossible for a datacenter to meaningfully heat more than the air in its immediate vicinity.

It’s anti AI, so people would actually believe the data centers are going to singlehandly melt the icecaps

Well I mean not from the waste heat but they have expectations of GigaWatts of new sustained power because they always want to run. The US has on order of 1-2 Tera watts of power capacity so you are talking about .1% of the grid power if a hyperscalar datacenter takes 1 gig of power. I've seen projections of need 50-100 new gigs of capacity. We will see if that actually happens but if it does we are talk 5% increase in grid loading. It sounds small but that is a tremendous about of power.

I mean there are a lot of solutions to making more power or making more efficient chips but to trivialize the impacts of AI as anti Ai propaganda which is how this comment comes of its a bit propaganda minded itself. I think backlash to AI is direct result of strawmaninh Anti AI as having only deranged opinions and anti progress. Where the datacenters are located people suffer because of high velocity don't care about consequences thinking. Every industry has to planing around people or people will do something crazy like burn the centers or try and nationalize data centers. I definitely think that would be stupid but don't underestimate stupid

> the way we heat up the earth right now, i don't think you have to worry about heating So what, winters would be no more? Snow will disappear, no more ice-men and christmas trees, and subzero conditions in general, too?

And no more food. Or at least not enough of it to feed very many people. You do eat, don't you?

As the earth has warmed over the last century, has food production increased or decreased?

If production increased (dramatically) while temperatures increased in the past, could this trend continue?
