Is it feasible to do this at smaller scales? Would be cool to use my compurers to heat water at home. Put all that useless heat to good use. Air conditioners could do it too, right? Pump heat into a water reservoir instead of just throwing it away?

I have a pool heater and an air conditioner, and I'm running both at the same time. They're fifty feet apart, but this thought crosses my mind constantly.

> Start-up Deep Green charges clients to use its computing power for artificial intelligence and machine learning. What about running the compute workloads of the municipality instead?

I doubt the municipality needs 28kW of GPU compute, and certainly not at the prices someone like Deep Green is going to be charging.

All data centers that are in controversial areas should offer free heated swimming pools for the neighborhood. You could add a giant pool complex as a percentage or two of the cost of a big data center.

Surely it's just cheaper to build further away from residential areas? For this to work you'd need to be close to residential areas, but that's where you get the most NIMBY opposition. And if the datacenter is in the middle of some industrial park, who would want to drive 30 minutes to an industrial park to have a swim?

The last place I lived, the nearest data centre was a few hundred meters from the local swimming pool, in a business park. Most people would never have known the data centre was there.

Elsewhere, e.g. in London, Docklands is both full of high density data centres and high-end residential buildings and offices that could certain use the waste heat in winter at least.

Most of the data centres there just looks like office buildings on the outside, and most residents won't know they are there.

The best waterparks in Tucson, AZ were on the outskirts of the city and worked great as a place to "travel" to for the parents as the kids would be wiped out on the way back. Breakers....Justins....how i miss those days of running around on hot pavement or gravel in bare feat only to also step on some cactus...

Something I have been wondering: Why don't data centres use the excess heat for a sort of energy recuperation, turning at least some of it back into electricity?

The degree to which you can extract energy from heat depends on the temperature difference compared to ambient. Efficient power stations all need super heated steam (like 600C). This would be like 100C max which is not very useful for generating electricity. It's fine for heating houses and swimming pools though.

What a useless article! I found some actual information here: https://www.techspot.com/news/97995-data-center-uses-waste-h... The "data center" produces about 28 kW of heat and the swimming pool has cut its gas bill by 62%. They are saving US$24,000 per year.

I don't know about in swimming centers in England but I do know YMCAs in the US often have budgets that look like:

- Revenue: $25.01M

- Expenses: $25M

So "small savings" like this can add up for them.

I have connected the radiator of my homeserver liquid cooling setup to the heat exchanger of my hot water heat pump. Not sure how efficient it is, but I get a measurable drop in CPU temperatures while the heat pump runs.

An outdoor heated pool that’s open all winter in a cold climate would be a destination worth a drive. A rather decadent use of energy otherwise, it’d be a good use for waste heat. There’s prior art in the Blue Lagoon in Iceland, a destination spa that uses water from a geothermal power plant.

> "Sean Day, who runs the leisure centre, said he had been expecting its energy bills to rise by £100,000 this year.

"The partnership has really helped us reduce the costs of what has been astronomical over the last 12 months - our energy prices and gas prices have gone through the roof," he said.

...

Last summer, BBC News revealed 65 swimming pools had closed since 2019, with rising energy costs cited as a significant reason."

That's terrible that pools are closing. No one even builds new public swimming pools anymore, so it's awful to close the few that exist.
