I'm sorry, does this article say which metals were discovered?

But he was Finnish
But a Swedish speaking Finn and it seems he made his discoveries while living in Sweden. From wikipedia: "Johan Gadolin was born in Åbo (Finnish name Turku), Finland (then a part of Sweden)." [0] "In 1779 Gadolin moved to Uppsala University." Uppsala is in Sweden. [0] https://en.wikipedia.org/wiki/Johan_Gadolin
> Finland (then a part of Sweden)
If Gadolin is Finnish, then, by the same logic, Immanuel Kant is Russian, because his birthplace, Koenigsberg, is a Russian exclave now.

> "Rare-earths" are not, incidentally, needed for electric vehicles, wind turbines, or solar panels, however much certain people wish they were, or confidently claim. What exactly does this mean? EVs use a ton more rare earth minerals than conventional cars https://www.iea.org/data-and-statistics/charts/minerals-used... Solar panels use silicon, indium, gallium, selenium, cadmium, and tellurium. Neodymium and dyspros…
most solar panels do not currently use indium, gallium, selenium, cadmium, or tellurium, none of which are rare earth elements (though indium is pretty rare) the solar panels that used those cannot economically compete with silicon pv for utility-scale solar any more (perhaps that will change) silicon is also not a rare earth element (and is not at all rare) evs and wind turbines can use rare earth elements, it's tru…
Silicon is perhaps the most available element on earth after nitrogen hydrogen and oxygen. Over a quarter of all rock by mass.

That's what I was going to ask: can anyone comment as to whether this is a disruptive event? Or is Europe so ordinarily devoid of such metals that it's comparatively little versus world supply?
About 3% of rare earth metals mined globally are mined in Europe currently. About 30% of the global supply is used in Europe tho. That doesn't really indicate how much is available in the ground, but only what's being actively mined. Someone else wondered about concentrations of rare earth metals in the ground in this finding, and it's "unusually high: 0.18%" My source is both paywalled and in Swedish, sorry about th…
Doesn't seem to be pay-walled at the moment although DN does encourage you to log in.

The graph you linked shows that this is not true. See the tiny purple graph at the right side of the bar? That's the rare earth minerals and their amount in an electric car is tiny.
Right, says "0.5 kg 'rare-earths'" per vehicle. A biggish camera drone uses more.
What is so special about a drone?

None of those used in solar panels are lanthanides. Current EVs use some lanthanides in magnets (soon to be displaced, as noted), but not in the batteries. Permanent magnets are used mainly in the smallest wind turbines, where offshore turbines are the biggest.
I see. I didn't realize "rare earth minerals" had a specific chemical definition
It's just a name. They are not necessarily rare.
It should be "certain transition metals", but transition is not what it seems in regard to "changing" in the common sense, either.

#279800 mio tons in china, 1 mio ton in sweden. So, four years of worldwide supply, unless we start building more electric cars.
#fuckcars, IMHO. Trains are nicer and bikes provide exercise, but the world seems to rely on two-ton vehicles for mostly one occupant, except for kei cars.

i'm genuinely curious what about their comment makes them an asshole. the comment is a bit dismissive, but hardly assholish
The combination of being dismissive and adding nothing to the conversation is what makes it assholish. Their only contribution was to shoot down what was an interesting aside.
I don't particularly like the way the comment was delivered either, but it does add to the conversation (as evidenced by the other comments that respond to its content and not its tone). The comment in question is bringing up the point that geography may have something to do with the reported stats, which is another interesting thing to keep in mind.
