Pretty soon you’ll just have nuclear plants just to power data centers.
Come to think of it, you would think power generation would perceptively increase the temperature in the surrounding air and while I have heard of nuclear plants making bays or rivers a few degrees warmer near the plant I don't think it's even been described as this bad.
Putting on my ME hat. Power systems are designed to extract the most amount of energy of their fuel sources. This leads for waste heat to not be significantly above ambient temperatures as they have extracted about as much as they can from it.
I assume now many high end servers are now water cooled, so that probably improves their cooling performance of their system, vs the older ways of aisle cooling and having hot and cold sides of the rack.
But unlike power stations, I don’t think the data centers have incentives or the ability to extract much useful work from their waste heat, so I’m sure they are dumping it as fast as they can plus the waste heat from all the secondary systems, cooling, water pumps, etc. are just compounding the local air temps.
Didn't Microsoft try to pay for a nuclear plant to be recommissioned just to power a data centre or something?
There have been several data centers that have bought nuclear plants, including Three Mile Island, they're going to fire that bitch back up, also the Regulators have been disempowered. Propublica on the last part if I recall.
something tells me Datancenters power needs will exceed that of old nuclear plants, since they are tyring to expand.
You'll need the same number of cooling towers for the computers too. All the energy created by the reactor will turn into heat, essentially doubling the amount of cooling needed.
I don't know why they don't use geothermal cooling, especially with the footprint these things have. Compared to everything else it wouldn't increase the cost that much, depending on how they do it, and even if it didn't cover all the cooling needs it would cut down a lot of it.
I have no idea, but I suspect geothermal cooling doesn't work as well at this scale. I suspect heat in the ground spreads far slower than the air moves. Since these are running 24/7, this means it'll reach an elevated equilibrium temperature that will be higher than if a residential house did it. I guess if the footprint is large enough it'd be fine, but that's probably really expensive.
Nuclear plants to power data centers to make ai slop to make more need for data centers to feed us ai ad slop...when does it fucking end?
I hope some vigilantes start taking action against these damn wastes of space.
Have you seen the movie Bugonia? I’m nearly convinced that CEO’s are all human looking aliens that are determined to destroy earth and enslave humans. #tinfoilhat #downtherabbithole
The disease is late stage capitalism, the symptom is a mad dash to trade our natural resources for energy and pollution. The mad dash will continue as long as we're bleeding humanity to keep the shareholders high and dry.
