"leaking" is the wrong word here - it implies some sort of inefficiency, process which is not working as well as it needs to. Leaky bucket, leaky faucet... That's not the case here, that center is __dumping__ heat into environment - it is by design, all that electricity is being converted into the heat. By design, it's enormous electric heater.
> By design, it's enormous electric heater. You're right, it's not leaking, it's dumping excess heat on purpose. However, I get triggered whenever someone uses the term "by design" wrongly. The generation of heat is not by design. It's an undesired side-effect of the computing being done. "By design" would mean that someone decided that there should be a certain amount of heat generation and made sure that it happens…

Technically it is inefficiency. The electricity should be doing computer things. Heat is wasted electricity. Just there's not much the data centre could do about it.
Even if the computer does perfectly-efficient computer things with every Joule, every single one of those Joules ends up as one Joule of waste heat. If you pull 100W of power out of an electric socket, you are heating your environment at 100W of power completely independent of what you use that electricity for.

#133I always wondered if anybody has calculated how much of our global heating could be attributed, if any at all, to every electronic device, server, and engine outputting heat as a byproduct.

> every single one of those Joules ends up as one Joule of waste heat. Yes it ends up as heat, but with some forethought, it could be used to eg heat people's homes rather than as waste.
You can say that about any waste heat. In really, it’s not convenient to move all waste heat to where it’s more needed.

These days it's not rare to have data center heated buildings. I guess crypto bros are just not thinking about this. But technically if could be done there too.

There was a startup in EU which explicitly sold heat from crypto mining to the local energy provider. IIRC it was also here on hacker news some time ago.

When you compute some nice and elegant result, dissipated heat is an undesired side effect. But let's face it: we are speaking about proof of work. Proof of work means that a computed has run during some "required" time. In other words, you have to prove that enough heat has been dissipated. Waste of energy actually is "by design" here.

Only true for our current computers and not true with reversible computing. With reversible computing you can use electricity to perform a calculation and then "push" that electricity back into a battery or a capacitor instead of dumping it to the environment. It's still a huge challenge, but there is a recent promising attempt: "British reversible computing startup Vaire has demonstrated an adiabatic reversible comp…
Actually pretty cool - I was about to comment “nice perpetual motion machine” but looked into a bit more and it’s much more interesting than that (well, a real perpetual motion machine would be interesting but…) Thanks for posting. Pretty cool.

It'd be super fun to take that as an axiom of physics then to see how far upwards one could build from that. Above my skills by far.
it's called the first law of thermodynamics
