I went down a rabbit hole reading about metals and mining and just thought it was interesting. Not an expert or a nefarious actor, unfortunately.
If it helps, I know @noleary and can confirm this is a true statement!
Osmium in powder form will oxidise to osmium tetroxide, and you want to avoid that because it stains just about any kind of plant or animal tissue including the surface of your eyes, and is spectacularly poisonous.
This isn't true.
I understand why you said it. Always 5 years away from being 5 years away. Years and years and years of nothing and hopecasting. Post-COVID market antics. Well-educated people pointing out BS and that even the best shots we had were example systems that were designed to be briefly net-positive in the 2030s.
But it's just not true.
Commonwealth Fusion Systems. Book it. 2027. They've hit every milestone, on time, since I started tracking in...2018?
> how do you efficiently harness 1,000,000C heat?
We get power from the sun very effectively over 150 billion meters of vacuum.
Biggest problem with fusion is doing the fusion for a low enough input power (or for pulsed, energy) cost.
If you use a steam engines it doesn't matter if your source of heat is 900C or 1000000C, all heat will be captured, and 40-60% will be turned into electricity.
I can only ever make material conditional claims about things like this :)
Far from a slam dunk, but I don’t think we’re as far from net gain as we were 10 years ago.
Very carefully.
There is an implication here that the United States is immune or afraid of doing “hard” or “dirty” work and so we outsourced refining and mining to China.
This doesn’t seem to be correct.
China has a national strategy to dominate refining of rare earth minerals and critical components and our entire society wants cheap products and China was the cheapest place for this stuff and environmental rules are more lax, and with an authoritarian regime supporting and fast tracking the business for strategic reasons, well there you have it.
Part of the strategy involves decoupling China from a weak link in the energy supply chain infrastructure: oil and refining rare earths, manufacturing products that use them, and more is how they are pursuing some level of energy independence from the USA which controls oil flows globally, for the most part.
With respect to avoidance of “dirty” jobs. The EU is far, far worse in this respect than the United States is or was.
We outsourced refining and mining to China because 1) it was cheap 2) it meant poisoning the ground and air and ripping up vast tracts of land somewhere else.
China's rare earth metals stratagem I believe grew out of this--it didn't happen immediately, but rather some bright bulb saw the growing reliance on access to the minerals and encouraged internal growth and acquisition competing resources. Absolutely, very clever.
I want to be very clear here to avoid any misunderstanding of an application of moral judgement against the United States for "outsourcing dirty jobs".

This could be true. The truth is likely somewhere in the middle, in that China never intended to join a US and European led world order because doing so would compromise the power of the authoritarian CCP (free speech, free markets are incompatible with communism) and this became the eventual strategy to work toward energy independence. Of course "independence" isn't a real thing here, just less reliance. You can't run fighter jets or tanks on batteries or solar panels.
Well yeah. Because we care about the environment and people like to enjoy their retirement instead of sitting in a wheelchair with COPD due to inhaling a lifetime of toxic dust.
China is getting better at it too, but only a few years ago I remember a story of all the toxic lakes where all the byproducts of neodymium mining were dumped.
Evidence: Long history of us doing exactly that.
Valuing convenience, modern products etc does not mean one "doesn't care" about the negative externalities, just like going out to eat at a nice restaurant doesn't mean someone "doesn't care" about saving money.
All products from China are manufactured with electricity that is largely coal.
You just mean it's not economical.
> I'm sure push comes to shove, US can import a bunch of central Americans to do hard and dirty work in mining.
Yea let’s ban migrant labor and the entrance of migrants now so we don’t have this moral failure. :)
By the way, the east (as opposed to the west) is fine with migrant labor too. That’s why remittances are a thing. Well, when they’re not being xenophobic or whatever.
1: "We need to be more self-sufficient with minerals!"
2: "Let's try to kick-start more of our own industry digging it up!"
3: "Wow, that's expensive and can't compete with international prices."
4: "Better shut it down!"
5: Goto 1
Without ever getting that the point was never to be as profitable as overseas sources. Or getting the point and ignoring it.
The acid is natural btw just from things leeching out of the rock walls.

Also, nobody forced US companies to sell those assets.
The history and asset ownership is also quite convoluted. Try this Wikipedia article:

This article is quite good at explaining how China cornered the market:

Just a nitpick, but it is the reverse, the United States has become more adversarial. China isn't kidnapping heads of state.
I think it's the other way around here. I say that as China's policy has primarily focused on self-reliance to the degree that it's overshadowed the west in several sectors with the exception of a few (Tech/AI, Finance, Bio) and given their persistence to close the gap I'd say we aren't too far from being eclipsed entirely.
One just has to look at the economics of it all and come to the conclusion that many have already arrived at...
