It’s pretty incredible, especially given that the free education in France is actually rather decent.

A few AC is one thing. Many AC in a limited space covered in concrete with almost zero tree in the area is another thing. We need to be more specific about what we are talking about. Anyway ACs are not enough in a city. ideally you also want streets with a significant amount of trees and greenery so that there is significant shade and heat from sunlight doesn't radiate too much from concrete/pavement.

France is not under threat from this.

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.

Silence! Do not let fact and reason stop the woke or anti-AI agenda! Only emotions count in this space!

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…

Already done and in use in the nordics. Most likely in most dc:s in the northern hemisphere with cold winters.

Well, you can wait for greenery to be planted and grow around houses. It'll take 10-20 years. Or you can wait for your landlord to install the shutters (will never happen). Alternatively, you can get a portable inefficient AC and save yourself from 40 degree heat in a rooftop apartment. The mental toll of sweating 24/7 for months is just too big to theorize about the best way to combat global warming.

I’d love that heat in the winter. Imagine, free heat! Linus heats his pool with excess cpu heat. It’s all about using things wisely and not panicking. AI and datacenters are here to stay, you can’t fight them, but you can leverage their waste for profit.

Sounds more like a threat than something desired

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?

Not sure it was a disingenuous comparison. If they’re saying the heat from a DC is drop in the bucket provided by the sun (in a given area), then that heat would indeed be negligible. On the other hand, if that heat comes in water form, and upsets the ecosystem (in a given area), then that would be NOT negligible. Not really about optionality in either case.

Your logic is solid, but their usage kinda implies the opposite (that skylights would make summers worse, not winters). That seems possible given the obvious dynamics of increasing the amount of direct sunlight, but based on a quick Kagi the overall effect is actually good for both summer and winter if used instead of windows rather than in addition to windows: Introducing skylights allows the total fenestration area…

Probably less good if you want to enjoy the view horizontally.

Cameras and screens. /s mostly

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…

nothing wrong with nationalizing
