Why would the Netherlands have power outages?

Being dutch you won't have CH4 shortages this winter (unlike what the EU might face). You'll supply your own industry, power stations and homes first and then your gas clients. You also only have one real natural disaster to optimize for, flooding. Europe has incredibly mild weather compared to the rest of the world.

Add to that that your infrastructure is newer than N. Americas - it all got rebuilt after WW2. The supply cables into my old house were 100 years old.

Finally, there is heating. Most homes need some form of an electrical motor for their heat (either as a blower for the furnace or a pump for their radiators). Consider how lucky Europe is climatically: the Netherlands is 52N. By comparison, Toronto is at the same latitude as Nice - this is due to the Gulf currents. Pipes in the Netherlands will not freeze if you spend a few days without heat. The pipes in the homes in the upper half of continental US will burst after a few days without heat.

Finally, generators are not particularly bad for CO2 emissions or other pollution compared to the grid. Not when you consider their low usage. We can afford them, they address real problems, they're fairly benign, so why not?

EDIT: clarity

"I think for those who would ban guns, they're probably more concerned with the overall rate of gun homicide, as opposed to specifically about mass shootings. "

That's what most would claim, but the issue is mostly emotion driven and mass shootings are extremely emotional. Overall gun homicide is actually not that high, in the sense that most of it is ancillary to other crimes (burglar getting shot, drug dealers playing footsie, etc). The chances of being killed in the US by a gun are quite low.

Just this weekend an Italian was knifed in NYC. I wouldn't blame guns, there were none, or knives. I'd blame the perp and society (i.e. Columbia University) for telling naive foreigners that a city like NYC is safe at night.

Where do you get those numbers? Did you forget a period? Or are you comparing gross numbers and forgot to normalize? You're off by an order of magnitude!

The US is, generally, very safe. And I'll gladly take a 2x or 3x increase of a very rare event to not have to live in Canada again. I grew up there and... yuck (To the Canadians here, please understand. I grew up in the GTA)

That being said, mama raised no fool. I don't and wouldn't live in a defund-the-police city.

Once you have high strength steel tubes freely available in a HD store, the rest is pretty easy. Also, I'm amused by the lack of concern over crossbows and archery in general by busybodies.

The article you linked says that it's a myth that most gun violence is committed by drug gangs. OP didn't argue that, he argued that most mass shootings are gang activity related. At no point does it mention mass shootings.

I was being facetious to remind Europeans that their criminals have guns, better guns than criminals in the US do. The DIY scene in Europe is quite healthy, so of course someone will make a DIY gun.

Amen.

It's so annoying how people don't realize how manipulated the word "mass shooter" is.

You can make an ar-15 receiver (legally the gun) out of plate steel from Home Depot and some spacers. The build is from the glory early years of the internet (90s?), so instructions are kinda hard to find. Why bother? CAD drawings for a $800 mill machine are available everywhere. Really, if you've ever held a receiver you'd realize how... primitive it is.

Europeans don't DIY guns because you're next to enough failed states to easily get fully automatic rifles. Why trouble your self with a building a semi-automatic when you can buy the full auto version? Except for Sweden and the UK. They prefer hand grenades and knives respectively.

Now I want to make two batches of coffee and measure the resultant coffee's temperature.

I have three, 1 cup, 3 cup and 9 cup.

1 cup is for me and my wife (we wait while the other finishes)

2 cup is for when we a guest

9 cup is for my 70 year old parents. I cringe just seeing them drink 4.5 cups each.

Interesting, but I think it's exactly opposite - I would think using water at 4C (the densest water gets) would give you the lowest brew temperature.

With water at 4C, puts the most water inside the pressure chamber, leading to the greatest pressure change for a given delta(T). Instead, if the water is just below boiling, the water going through the grinds must be higher than 100 C (since the pressure raises the boiling point).

It'll brew faster, and there is an argument to be made that quicker brews lead to less burning. But the T would be highest.

How? Was it fake?

You must understand my amazement. To blow up, the Moka must not have had a functioning safety valve (check the side). Furthermore, the grid must have been so crusted up that, in the days (months!) leading up to the fateful event, it would have taken a very long time to brew what would have necessarily been an extremely bitter coffee.

The only was I see this happening is it:

- The Moka is fake and it blew up on its first use (since the grid must not have had the holes pressed into it)

- You weren't aware that the grid is removable and didn't clean it. I also like to push against the safety valve form the inside every now and then.

But if #2 why did you put up with a bitter coffee that would take ages to brew?

My 2 cents:

- Al is a known neurotoxin

- Al does not, typically, rust, despite being far more thermodynamically favorable than Fe because a kinetic barrier, AlO2, forms stopping further oxidation

- AlO2 is an extremely durable coating. Extremely inert. It's crystal lattice constant is similar to Al's to it does not flake

- Al does rust in salty environments.

Conclusion:

The moka is fine. Just don't use vinegar or salt water to brew your coffee.
