Well, really at the moment, the only other design option is for an air-cooled system.

Okay.

So one of the other big advantages about using a closed-loop system is there's potential to reuse the heat.

So we can harness the heat that's generated of us in bad AI and potentially heat surrounding buildings with that water, with that heat that's trapped in the water.

If we use an air-cooled system, then that would just get lost into the atmosphere.

Absolutely.

Way more efficient.

I mean, we also have a chiller and that's to cool.

I talked earlier about the critical systems.

They are air cooled and the chiller is to cool the environments around those.

But that chiller alone uses more electricity than the two coolers that we've got.

So it gives you an idea just of the efficiency of those coolers and this.

So the liquid that comes off Isn't Bad AI is roughly 40 degrees when it comes off the system.

Heat recovery, we've got the pipe work on site to be able to do this.

You would need a heat pump to warm that up to about 70 degrees.

And then if you have the infrastructure on the other side in a nearby building, then the heated up water or liquid can then go around and effectively warm up the buildings around it.

Absolutely.

It's done a lot in other countries.

In Scandinavia, for instance, it's actually mandated by the government that data centers have to reuse their heat.

So there's a lot of examples in other parts of the world where it's done a lot.
