There are studies showing that children who are spanked have worse outcomes, or are less disciplined or something (can't remember the exact details). However, these only show correlation and not causation. I can see children with the worst behaviour being more likely to be spanked as even if their parents are against it they might feel they've tried everything else and resort to corporal punishment. Alternatively, parents with the sort of anger/self control issues that would leave them more likely to hit children might be worse parents in other ways.
So, my parents did maybe 2-3 times when I was young, and really didn't like it, and never did so in anger, and only after explaining why carefully. I don't feel that this was at all traumatizing to me. But I definitely see how it would be easy to do so in less humane ways, and that risk is probably not worth it.

⇑ From another article linked from that one:
- It would create a new governing agency, which would issue blanket mechanical licenses to digital services, and collect and distribute royalties to rights holders. (This wouldn’t prevent rights holders like major labels from entering into licensing agreements with digital services.)
- Mechanical royalties would be paid to songwriters whenever a copy of their track is made (be it physical or digital), and it would be based on what a buyer and seller negotiate in an open market, instead of the current rate-setting standards.
The most major change would be the new agency, which would solve the biggest issue for songwriters: getting paid on time. As part of the bill, the agency would create a public database containing song ownership information to help songwriters identify which songs haven’t been properly attributed to them. It would also help streaming services like Spotify and Apple Music avoid lawsuits for not properly identifying the rights holders of songs on their services. (Digital services wouldn’t be liable for statutory damages, as they would no longer be responsible for identifying rights holders.)

@TimeBandit In a country where all passenger rail lines are electified, how is this more environmentally friendly?
It'd be different if it's running on non-electified lines but I doubt northern Germany has any.

Plenty, actually. While electric trains transport about 90% of goods and passengers in the country, only some 60% of the network is electrified.

Right; but it's not like there's some mysterious force-field that envelops Europe and if a pickup truck enters it it dissolves into magical butterflies, right?
Apparently there's one around the US that causes certain models of passenger cars to transform into commercial vehicles shortly after arrival. So who knows what they have in Europe?

Hydrogen's strong energy density
? Hydrogen at 700 bar has still just 9.17 MJ/l, compared to 35.8 MJ/l of diesel fuel at atmospheric pressure¹.

@Bulb But it wouldn't fit the KLEEN ENURGEE narrative to explain the difference. So, no explanation for you!

Being more concerned with energy-per-weight than energy-per-volume fits nicely with railway mentality…

@dkf … the low weight is probably more than offset by the weight of the pressurised container anyway.

I just had a thought that hydrogen liquified by pressure alone might be viable for trains due to the weight capacity.
A quick look at the phase diagram says the hydrogen would be at about 3000 bar. So, you'd only need a pressure vessel with 50 inch walls...

I think he wants to liquefy hydrogen through pressure alone, without cooling it, which would require much higher pressure than the 1000 bar line on that diagram. However, from what I can find online, it appears that hydrogen will solidify under high pressure at room temperature, rather than liquefy. Further pressure will eventually convert it to a monatomic (H, not H2) liquid, but the pressure required is in the neighborhood of 500 GPa (5000000 bar).

To get a supercritical fluid with a density the same as cryogenic hydrogen at atmospheric pressure you need to acheive 77kg/m3
Then I used this graph:
Then I cocked it up by remembering 3000bar from 2300bar....good news though, that'll mean the walls can be slightly thinner!

Yeah, I don't know if this would actually work. Supercritical CO2 is scary enough, supercritical hydrogen is just insane.

OK, but if you can get by with 700 bar and half the density, why bother? It's not like there wasn't any room on trains as long as the stuff doesn't get too heavy.

It was just a silly thought that room-temperature liquid hydrogen would be cool. If it's still a gas and not a liquid then it loses style points.
I think anything that contains hydrogen at integer amounts of bars should be looked at sideways, let alone hundreds or thousands of the damn things!

I wouldn't consider hydrogen or gasoline to be explosive, although they are certainly quite flammable. Their burn rate is fairly slow and heavily limited by access to atmospheric oxygen.
Explosives tend to be self-oxidizing compounds or otherwise generate tremendous amounts of hot gas very quickly during decomposition even in the absence of oxygen. Like nitrocellulose, TNT, or nitroglycerin.
Also, I am not a chemist nor did I stay in a Holiday Inn Express last night.

One issue with hydrogen is that it leaks (in gas form). Badly. It's so light that it diffuses through solid metal, and the molecules that don't diffuse through make the metal brittle instead.

The thing with hydrogen is that, for an explosion to occur, you need an oxygen-hydrogen mixture above a specific ratio. Stay under that ratio and hydrogen will simply burn.
There's a rather simple experiment you can do to prove that you need a minimum amount of oxygen: Take a tin can which is completely open at one end and drill a small hole into the closed other end. Put the tin can on a table so that the small hole is on the top. Close the small hole (for example, with a finger) and then fill the tin can with hydrogen from the other end. Hydrogen is lighter than air, so it will pool "upside down" in the can.
Then put the tin can on a small object (like a match) so that it stands skewed with a small gap between table and can at the bottom.Now take a lighter, remove your finger from the small hole at the top and light the escaping hydrogen.
If you filled the can completely with hydrogen there will be no boom, just a small, hot and nearly invisible flame at the top. However, you'll also hear a whistle-like sound which will become deeper fast. And then the tin can will jump into the air with a loud boom.
That's because the hydrogen is sucked through the top hole while air will rush in through the bottom gap. And at some point you'll reach the proper mixture to get an explosive hydrogen-air-mixture. But before that? Only a hot flame.
Now, here's the thing: That mixture will need to be created inside the container. And it needs the proper ratio. Now, say, the container for the train has sprung a leak due to an accident. Hydrogen will escape, yes. But remember that it's lighter than air - it will escape into the sky, fast (unlike gasoline which will pool around the container).
And even if there's a spark you'll only get an admittedly hot flame. But no bang.Which reminds me: Didn't we have this discussion before? Because I distinctly remember discussing the Hindenburg which also wasn't an explosion.
