The EFI partition is unencrypted.

“you don't even need to plug an external storage device, you can just pull out the disk, copy the files in the EFI partition, put it back and it will still work. That's how bad it is.”

3GW/9GW is peak load, as I understand it - data centres usually operate at 85-90% of peak load according to Goldman Sachs.

Meanwhile, the 4GW figure is average demand - Utah consumed 35,075GWh for 2025, so average demand of 4GW (35075/(365*24)).

‘More power than an entire state’. Yep - take the Stratos data center project in Utah, the first phase of which is expected to consume 3GW and at full capacity is expected to be 9GW. By comparison, the entire state of Utah currently uses about 4GW.

Estimates suggest they could save U.S. consumers billions of dollars a year in electricity costs, while potentially offsetting thousands of megawatts of demand (https://www.sciencedirect.com/science/article/abs/pii/S09601...)

Plus it increases equity because this primarily opens up solar for those in rented accommodation and apartments/flats who otherwise couldn't access it. Personally that feels well worth pursuing if it's deemed safe.

My understanding is that is why they are limiting to 800w (~4A) at least in the UK's BS 7671 Amendment, which they consider well within the designed safety margins.

Unfortunately most people's actual usage patterns for plug-in hybrids appear to make them worse than just a straight up ICE - https://www.theguardian.com/environment/2025/oct/16/plug-in-...

How exactly? Meta isn’t doing this out of generosity to society. They’ll be consuming this and vastly more energy to ultimately increase their own profits?

You actually don’t need (long-lived / hard-coded) secrets in this scenario if you use OIDC:

I wonder if this works more reliably than airdropping between my iPhone and MacBook… which seems to be 50% success rate at best.

Until recently, the geographical locations where geothermal is feasible and economic was very limited. Ironically it is tech from fracking/shale gas that is starting to open up a far wider range of possible sites at lower cost.

which is why dispatchable power is required - not coal?

Nothing to do with the blackout in Spain - https://www.reuters.com/business/energy/what-caused-iberian-... - voltage surge and various thermal power generators failing to provide the voltage correction services they were being paid for

But yes, grid following alone does not provided the required stability - synthetic inertia etc needed

Baseload is traditionally about generation, not consumption. And baseload generation only makes sense when it is the cheapest option.

When solar and wind produce at near-zero marginal cost, running inflexible baseload beside them just forces cheaper generation to switch off, driving up system costs.

What the grid needs is dispatchable capacity - batteries, hydro, gas peakers (if we must) and demand shifting - that can plug the gaps when cheaper forms of generation cannot.

I had a similar experience and backed away from using it - non-spam emails were getting spam filtered without visibility or notification.

The investigation has shown it was in fact nothing to do with renewable energy sources despite the noise made at the time - https://www.reuters.com/business/energy/what-caused-iberian-...
