I never have any cash on me. That would’ve sucked.
I spent my last 5 euros on a sandwich and a croissant to eat on the walk home. All in all a pretty decent experience.
How do energy intensive processes like aluminium smelters or window glass producers preven their machines from self destruction ?
In some cases they don't have any practical ability to. The Texas winter storm resulted in a lot of scrap at semiconductor lines due to power loss. There are industries that are completely dependent on grid power. You can't generate enough on site to back up 100% of your operation. Think about how much power one EUV source consumes. The only reason Samsung is building additional factories in Texas is because the loca…

How warm is "too warm"? I find cold beer, and cold soft drinks as well, quite repulsive. I usually try to order without ice entirely, and if I receive any bottles or cans, I permit them to come to room temp before consumption. Refrigeration is sort of a scourge to those who enjoy food. We are so used to simply freezing our esophagus and not tasting anything! Food is kept cold because it lasts longer, not because it t…
I was referring to the fact that generally people prefer cold beer, not room temp beer.
Do they? But why? Why would they? Are they simply accustomed to tasting it that way? I should say "not tasting it" because chilling a beverage basically kills its flavours, and they never make it to your tongue correctly.
I would say that many people would be surprised and amazed if they tasted such things as Pepsi without ice, and without coming right out of the fridge.
Unfortunately, any lack of refrigeration really messes up supply chains and will eat into anyone's bottom line, so it's not a realistic goal.
We had something similar happen in Tunisia in 2002. The reliance on diesel turbines meant a very long rebooting process. As a result, the government invested heavily in installing gas turbines all over the country. When we had another blackout event in 2018(?), it only took an hour or so to get things back again.
Why is that? Are turbines easier to speed regulate than diesel engines?
Spain is mostly back up. Plant startup is only the first step.[1] It's load pickup. Here is a PJM training module on load pickup during system restoration.[2] It gives a sense of how touchy the process is. Power network control has good control over generation and transmission, but limited control over load. When load is turned on, there are transient loads with different time constants. There's a huge load for the f…
There are costly means to compensate for the lack of spinning baseload but actually building these devices have been neglected, to no ones surprise.
Sounds simple, and I appreciate from experience a huge amount of prep and validation needs to be done in the background.

I have no idea how much power an EUV source consumes, but I’m surprised to hear that it’s more than a handful of kW. What’s the right ballpark?

First hit off google.
Assuming they run them 24/7 that amounts to a power usage a bit over 1 megawatt, but they could be pulsed for all I know and use quite a bit more

Yes, the huge rotating mass is inherently more stable than a diesel. They key to grid stability is mostly huge rotating mass, either producing or consuming.

Or I guess, by inference, huge battery banks.
