Im a bit clueless on this subject but I've been wondering why isn't this heat used productively to, say, generate electricity. Why aren't AI datacenters for example use the heat to provide the municipality with hot water for example?
Electricity from heat is generated by temperature differences. Large differences are much more efficient than small differences and data centers are "small differences" for these purposes.
Unless you can use the heat directly, it won't be worth it to convert it into electricity.
The server/ML GPUs are not great for gaming, they strip out all the specialized shader/pixel units to cram in more general compute cores.
In theory you could write games with just those but aside from the amount of work needed I'm not sure if the performance would be good enough, the specialized texture samplers etc can be faster than general purpose compute shaders.
Also, for cloud gaming you want very low latency, so few GPUs all over the world in local POPs, not a lot of GPUs in few large data centers.
"Trainium accelerator" doesn't sound like it would be terribly useful outside it's current niche. It's not clear how much of the spend is that kind of thing versus general purpose compute and storage.
This feels like saying when the dot-com bubble burst, could the servers be re-purposed as mainframes. Whatever about valuations and individual stocks, AI/LLM workloads are only going up.
I am more on the AI skeptic side (LLMs are not a path to general intelligence, coders cannot be 100% replaced with any version of product I have seem to date), but I fully agree. Some form of AI text generation is likely to be here forever. Maybe it gets vastly more efficient per clock cycle, but compared to N years ago, all of the tech vendors need more compute to offer this service.
>A year ago, a 1,200-acre stretch of farmland outside New Carlisle, Ind., was an empty cornfield. Now, seven Amazon data centers rise up from the rich soil, each larger than a football stadium.
Can't they find brownfield sites instead of fields
As far as "industrial" neighbors go, a datacenter is a pretty good one to have vs an abandoned husk vs an active polluter/nuisance, at least if that datacenter isn't run by a selfish psychopath that tacked on a bunch of gas burning generators to power the thing.
This comment got me wondering whether loss of farmland in the US is a serious issue.
It looks like there's about 800 million acres of farmland in the US and we're losing about 2 million acres per year to the land being repurposed. Despite that, crop production has more than tripled in the past 70 years due to technological advances.
That said, economic effects, loss of farmland, and climate change have contributed to slower growth and higher variability of crop yields recently.
In the past decade there's been a modest 0.8% annual increase in crop production despite losing about 2 million acres per year.
Yeah, it's not a significant amount of land. But it does seem like these companies prefer to take quality farmland instead of unused land. There's something similar happening near my town, where a company wants to put a big solar array on some prime farmland, and the locals are asking why that spot and not getting an answer. It might save a small amount on development, as farmland is fairly flat and has no trees to remove, but that's miniscule in the overall budget for these things, and rough ground would be much cheaper to buy. But the corporation behind it and the government entities involved are digging in their heels and insisting on using farmland, without any explanation why.
So it does seem like some of the people making these decisions just like the idea of taking farmland out of production for some reason. Maybe they just don't like farmers or modern farming methods. If that's their motive, they may not realize how tiny an effect they're having on the total, because most non-farmers don't really understand how much land is out there.
It's like the people who say Bill Gates is trying to control the food supply because he owns something like 270,000 acres of farmland. Even that just isn't that much, not enough for him to control anything larger than the horseradish market.
The problem is not the amount of land but if that land is economically viable. Farm already has low margins.so, if you grab a good location to build a data center and push the farm land even further away from population centers, then you are pretty much killing family farms.
There are virtually no family farms left in the US. Especially central Indiana corn farmers. 1200 acres wouldn’t be a financially viable corn farm if it were family farmed.
I think this is really close. My hunch is that agricultural land is just simply cheaper to acquire and convert, as compared to industrial land which may or may not have all kinds of remediation or razing that needs to happen to it first.
Also whether the farmland requires irrigation. In Ohio, there’s not much irrigation. In Indiana, you see it a lot more. In Idaho, it’s basically a hard requirement
One of the major problems facing American agriculture is that there are fewer and fewer farmers/farming families.
Farming is extremely money and labor intensive and there’s a lot of upfront investment with a lot of long-tail return, and it’s not “sexy” the way (for example) AI is, so there’s not a bottomless pit of cash to shovel into the furnace for a quick buck turnaround.
Independent farmers tend to seriously rely on good weather and a lot of advantageous tax treatment.
Of course massive agri-business would very much love to continue to fill more and more of the void left by the shrinking independent farming population. That has its own problems.
I don't know about Indiana, but in Texas companies buy farmland because it's often available near population centers and infrastructure. And the land is available because the existing owners do just enough farming/ranching to qualify for the lower tax category.
This particular site is being built basically in the parking lot/backyard of a steel mill, so it sort of is brownfield. I have a hunch that “empty cornfield” is just the author using some artistic freedom instead of saying “an empty field in the Midwest”.
It was definitely farm fields growing crops, you can look in Google Earth and see for yourself.
Edit: Anywhere in the Midwest where there is a large expanse of flat ground will almost always be growing crops or have a town built on it. Undeveloped land is almost all hilly and forested or floodplain, nowhere where you could put a data center.
Why? Hold outs, zoning, greedy politicians and more. I drove through a blighted neighborhood. There were 60-70% unkempt houses and maybe 10-15% in great shape. Some won't want to move for their own reasons and they'll refuse to sell. Some will just be trying to get more money. Others will be sincere. It's very hard to unsubdivide land.
And then there are the zoning and city regulations which naturally resist. You would think they would welcome a new taxpayer, but they're really in love with the regulations that someone wrote decades ago. The odds of getting them to bend is anyone's guess, but in most cases a bribe or ten is going to be required.

Sentences like this never ceases to amaze me. All of this juice to attempt to match what a single human brain can do with its relatively low resource requirements.
> Each year, it will use millions of gallons of water to keep the chips from overheating.
Growing corn on that same 1200 acres would require on the order of a billion gallons of water. People have no sense of just how much water agriculture consumes.
In all probability, putting a data center on farm land is greatly reducing water consumption.
Yeah. The power use is impressive, although still only 1/10th of the output of the largest power station in the world, the three gorges dam. The water use is not really a big deal at all. I don’t know why journalists inevitably have to mention both. And even the power numbers require much more careful contextualization.
I wish I had a good balanced article to link to when these discussions come up, one that really digs into the power use question and compares it to the power consumed by other human activities and capital projects. Does anyone know of one?
Doesn’t a typical McDonald’s require millions of gallons of water each week just for the beef alone, without even considering things like drinks and ice and boiling potatoes and washing floors?
By pointing out the obvious you miss out jumping on the bandwagon of everyone writhing in pain over how devastated they are for the environmental impact. Whenever AI is brought up you have to remind people how unsustainable it is and how it’s all about to fall apart and how the value isn’t there, among other topics. Off topic/on topic I’m reminded of death reports during COVID for particular states. When I went to go and look at the statistics of years prior to compare, they were at par if not less than the few previous years. Just an example of uncontrolled (mostly manipulative) outrage in action. I’d like to expect better of HN but I don’t: I’ve lost all respect for the moderation (dang and now tom) here over the years.
13 years is an incredibly long time for something as fast moving as data center development. I guarantee that a _lot_ has changed. I know AWS in particular has gone through multiple entire revisions of their DC designs, and I recall a talk from some of their engineers saying how AWS actually found it more economical to use less cooling and let their DCs run hotter than they used to.
Data centers may change but the physics of cooling doesn't.
It's more economical to run chips hotter but at the end of the day you'll still have heat that needs dissipating and it's hard if not impossible to beat evaporative cooling in terms of cost.
This is like someone in 1800 saying “at the end of the day you still have transportation needs and it’s hard if not impossible to beat horses and carriages in terms of cost”.
Literally just do a google search. There are advancements every day that improve upon evaporative cooling to make it use less and less water and energy, and alternative methods other than evaporative cooling.
I think you’re conflating things. It’s not a single human brain. It’s processing power to provide the human trove of knowledge and reasoning at the beck and call of millions of people nearly simultaneously. No single person would be able to do that.
It's a laudable goal to match human intelligence but we can't ignore the cost for too long. If humans can create the same reasoning for cheaper why would we chug along on this path? And this may be the case when the AI hype bubble pops and real economics take over.
This is not the intelligence of one person, even the most intelligent person but rather the intelligence (wisdom) of the whole crowd -the whole world democratized (I.e. available to everyone for a nominal fee).
And for the same purpose before that we had, or rather have, since it is still very much in use today, the Dewey Decimal System. Peering further onward still into the annals of library science, one can find even more creative and revealing methods of indexing human knowledge. In doing so, one might even be inclined to believe that the state of the science has come so far as to be considered solved. Alas.
I think if you went to the library and asked for information on "how to build a chicken coop" and the librarian took 60 books related to chickens and building and farming, cut up the words in them, then arranged them in a way they found satisfying, you might start going to a different library.

Electricity from heat is generated by temperature differences. Large differences are much more efficient than small differences and data centers are "small differences" for these purposes.
Unless you can use the heat directly, it won't be worth it to convert it into electricity.
Using heatpumps you only need a little electricity to heat quite a few homes with district heating.
But there probably is no nearby district to be heated.
And you only need heating for at the very most, 6 months of the year in the US. Though that's shrunk depending on region in recent years.
There are already some datacenters doing this: https://www.techtarget.com/searchdatacenter/tip/Data-center-... But for now, it's still the exception, probably because of the cost of such systems.
Once the overall AI bubble bursts/deflates, would they be able to re-purpose it for other workloads e.g. cloud gaming?
Though, maybe Midjourney or other niche AI companies could buy it for the right price I guess.

Decades of lies about nuclear has its downsides.
For something to be considered "sad", there needs to be an available, practical alternative. What should they have chosen instead?
We could not build new data centers and focus on fixing the real issues instead.
We could always revisit this decision once clean power is actually available.
Cover the roof in solar panels and use the power to do something useful instead of running bullshit generators.
Or maybe a park with some oak trees and a frisbee golf course idk.
It's either that or nuclear.

Not at all. I think it's probably the best option if you want guaranteed electricity.
