Was wondering if heatpumps would be the next step and on the site that is what they exploring net for the cooling side.

In parallel, the project will assess alternative LCT options — such as heat pumps and rooftop wind turbines — to identify ways to further boost SHIELD’s efficiency. As deployment begins, we’ll also explore how the commercial model can evolve to incorporate services like Distribution System Operator (DSO) flexibility and expanded P2P supply arrangements.

If we are looking at this kind of modeling hopefully district systems could be considered as well.

Well this is really cool.

Ive seen the large data centers handling heating for nearby residential units or in the same building, but not with a localized unit like this like you said.

I'm (hopefully) going to be getting some decent property for a farm, most likely will have to build, and this makes me wonder if a small setup like mine (a dozen or so machines) feeding before the heating system as a preheating (like solar water heating) would be worthwhile.

Going to have to have a chat with an ME I know!

So, what happens in the summer?

What I don't understand is what the Pis are doing at the moment to get hot as they say that they don't have any clients to do any work yet? So presumably they must be doing aimless processing to get hot at the moment.

You would've thought that it could be made more efficient by centralising these into hubs and piping the waste heat in the community as an array of Raspberry Pis doesn't sound great.

What would happen if they run out of things to process or, the inverse, have too much demand for processing and no demand for heat in the summer?

So it's eco friendly because... checks notes... someone else is paying the electricity bill? I don't think that's how things work...

So does the existing radiator network in the house just have hot oil coursing through it now?
