> That's the entire point of being in a cold place that you don't need active cooling. Just open the window.

> Even if the cooling is free? Not even free, the cost is negative since it saves heating cost.

Again, having cold air outside is not unique to residential homes. Locating somewhere cold is a strategy for cooling data centers as well. But it doesn’t make environmental management free. You still need to control humidity and move heat. You can’t just run a server outside. However, it isn't the only concern for hosting a compute workload.

> Can you explain the connection of LLMs to power density? This point makes no sense.

The system requirements for a single server to run a frontier workload is a system that would overwhelm the power requirements of practically all residential electrical systems.

> You can lock a box physically

If only ISO 27000/SOC/NIST SP 1800/PCI DSS/ etc were all that easy lol

> Why though if redundancy exists, like you said? Would they still struggle to compete if the cooling cost was effectively negative?

Because of the additional capital costs associated with buying more servers, the additional operational costs of inconveniencing your employees, and the additional operational costs of powering/housing servers that are down.

> You can make cooling cost negative, if that's the majority of the cost, then that's great!

It isn't, most power in a data center is spent to power compute. Even if you do harness waste energy (which some data centers do), it is at best 100% efficient. Residential heat-pumps already have effective efficiencies better than this.

> And you can also place your servers in residential areas with the cheapest power.

And in those places, industrial rates are typically even lower.

Scale is always cheaper.
