Random thought: Why don’t we have a server rack that runs at home but is managed by a company, then people or businesses rent them? Th important use case is that the heat generated can be used for home. Like property managers, business maintaining them are heat managers for home.

I feel like this idea would work better at a somewhat larger scale, like a small to medium datacenter heating an apartment or office building. The downside is for any of these systems is that when it's too hot outside that heat becomes a liability so you'd have to have the infrastructure to divert heat as well. The other downside is that you'd be replacing a very well understood technology with minimal maintenance requirements with a relatively complex technology with more extensive and complex maintenance requirements.

- Power fail-over (battery + generator backup) in every house?

- Could get expensive flying a technician to every household to upgrade hardware in the racks

- Probably don't want everyone at home having physical access to storage devices

- Massive theft risk

- Homeowner's insurance would probably be irked

All the problems you mentioned can be reframed as positive feedback for the economy we’re evolving into. Let me dream the arguments for each of your bullet points:

1. Power fail-over (battery + generator backup) in every house? - I recently listened to a Planet Money episode about how DC/AI infrastructure needs are driving up electricity prices in Ohio. Ordinary households end up paying higher bills while big entities plan/build for reliable power. - Maybe household-level infrastructure could be improved as part of making this kind of model viable. This applies to networking infrastructure too

3. Could get expensive flying a technician to every household to upgrade hardware in the racks - People with enough education can be trained, and with the incentive of being paid, households themselves could become the technicians.

4. Probably don’t want everyone at home having physical access to storage devices - Same idea: if households are being paid and it’s “their role” to manage, the access concern gets reframed as operational responsibility.

5. Massive theft risk - Theft risk already exists today (even in good neighborhoods). The incremental risk might be negligible.

6. Homeowner’s insurance would probably… - If we squint hard enough, there are arguments here too (e.g., payments not missed, additional compensation).

I don't have the full data on hand, but there are three companies in the UK working on this problem. Feel free to go down that rabbit hole.

from google AI, YSRMV (Your Search Results May Vary).

Heata: Attaches servers to your hot water tank, providing free hot water during trials, saving users money on bills.

Thermify (SHIELD Project): Installs "HeatHubs" (often with Raspberry Pis) in sheds or homes, running remote data centers and using the heat for homes, aiming for low-cost heating for tenants.

Carno: Offers devices like the QB1 (digital boiler) and QH1 (computer heater) that integrate microprocessors into heating systems, reimbursing electricity costs.

The value doesn't line up for anyone. From my perspective as a homeowner, gas heating is cheap, and replacing my gas furnace with someone else's server rack is of significantly more negative value than my current cost of heating.

I don’t heat my office, the reason being, when I run ablations for personal LLM research, it is enough for heating my office during winter. Given our move from just searching for links or website content to well-summarized content, maybe enthusiasts can have a private inference cloud where GPU sitting idle can be used for heating and generate cents with inference. But yes, all those points are valid, and that could be a moat for the business.

Data centre in the shed reduces energy bills to £40

Someone already made it a reality. Kudos. I think this is going to take off with right environment

I had a similar random thought: Why don't we have a cloud company that does something opposite to what a Cloud company usually does. Instead of renting out resources from a data center, they help company setting up local resources and sell/rent out the unused capacity to other companies/individuals?

Probably a bit of a nightmare to oversight all the resources and ensure consistency and privacy but hey why can't we dream?

Yeah exactly, I was thinking this would be a good solution for crypto mining rigs. AI is similar from a power requirement perspective.

This has already been done [0].

Of course crypto bros have tried it

Hard "no" to subscriptions and "cloud management" for shit. On-prem ownership or bust.

Residential connectivity sucks.

If you put a rack in a datacenter, and it's a decent datacenter, you'll probably have at least 2x10G connectivity off the rack; if you need more, you can get more. If you put it at someone's home, good luck.
