I'm still noticing a lot of hand-wringing about the EV credit on Twitter, so I think some examples are in order (made-up numbers on all, just as examples).

EXAMPLE 1:

Q: Tesla sells 1/3rd of its cars in the US. Of them, 70% meet the price limits. Tesla buys its nickel from...
free trade (such as Canada) and non-free trade (such as Indonesia) countries. How much of its nickel must come from the former for *100%* of what qualifying cars need to be free-trade-deal sourced?

A: 23%.

EXAMPLE 1B:

Q: What about for 40% to be free-trade-deal sourced?

A: 9%
EXAMPLE 2:

Q: Tesla's cells use $3k of critical materials. Tesla buys abundant >99% pure alumina (smelting grade: >=99,5%) from a free-trade nation, making it a critical mineral, and supplies it to a smelter for making aluminum parts for their pack.
If literally *every gram* of *every other* critical mineral was non-free-trade sourced, how much would Tesla need to pay for the bauxite to hit the 40% limit?

A: $2000

Example 2B:

Q: Name some examples of what else could Tesla do this with for things already in packs.
A: Ferrochromium for stainless steel - 60% purity; fluorspar for fluoropolymers, electrode binders, electrolyte additives, etc - 97% calcium fluoride or 99% fluorspar; manganese, for cathodes or steel alloying - manganese sulphate (any purity) or 99,7% purity; magnesium...
.. for alloys and metals - 99% purity; zinc for galvanizing, 99% purity.

Example 2C:

Q: What in the pack can you NOT have as a "critical mineral"?

A: "Not much". Iron and some alloying agents. Organic carbonate electrolytes. Copper (weirdly). Separator membranes.
Example 3:

Q: If Tesla buys $3k of foreign parts for their packs, how much do they need to sell packs for to justify an argument that at least 50% of their components' value is North America-sourced?

A: $6k, possibly plus profit, amortized capital, and/or labour.
Example 4:

Q: If Tesla's pack components are 25% North American and the total component cost is $4k, how expensive of *any* North American part *of any kind* do they have to stick in there for no good reason?

A: $1,3k.
Example 5:

Q: If Tesla 4680s use <99% purity metallic nickel or cobalt rather than battery-grade sulphates, are those critical battery minerals?

A: No.

Example 5B:

Q: If Tesla 4680s need 99,5% purity nickel, what % needs to be a critical mineral?

A: Only half.
Example 6:

Q: How could Tesla move things around lower their critical mineral count?

A: Cast/stamp a separate box. Call it all or part the BMS or thermal system. Put all your non-cell foreign components and critical minerals in it. Connect it to the pack.
Example 7:

Q: If Tesla imports critical minerals from non-free-trade countries, makes cells out of them, 20% of them fail testing, and they recycle the minerals into new cells in the US, where are those minerals considered to have come from?

A: America.
Example 7B:

Q: If Redwood imports waste cells from all over the world made from non-free-trade minerals and recycles them, where are those counted as coming from?

A: America.

Example 7C:

Q) If a smelting process that normally takes a 1% grade ore is instead fed a feedstock...
... of shredded battery packs containing 10% of the mineral, what will this do to the process's production capacity?

A: Hard to generalize, but in most cases, a roughly 10x increase would be expected.
In short... this bill is a sieve. Partly due to oversights, but partly *by design*. It's *by design* that recycled cells turn into domestic sourced materials. It's *by design* that a lot of minerals not normally associated with foreign dominance are on the list. And the even...
... if it didn't cross the authors' minds that what defines a "battery pack" is a flexbile concept, I seriously doubt they didn't consider that manufacturers would juggle their supplies to ensure that only US-market price-qualifying vehicles get the compliant-sourced supplies.
And if there's any company out there best prepared to meet this, it's obsessed-with-local-sourcing, obsessed-with-vertical-integration, critical-mineral-reducing, rapidly-iterating Tesla.

-= Against Blaming Mind Viruses =- 🧵1/25

As we all know, @elonmusk is obsessed with the notion that liberalism is a "woke mind virus" that is progressively destroying society.

In this, he refers to (without using or seemingly knowing the term) memetics.
en.wikipedia.org/wiki/Memetics
🧵2/25

Long before "meme" became an internet term meaning things like photos of a cat saying "CAN I HAS CHEEZBURGER?", it was a scientific term referring to a thought equivalent of genetics: cultural / social motifs passed down from parent to child, as well as horizontally.
🧵3/25

An example of a meme might be a proselytizing religion, where converts will then to proselytize to others. Or a philosophy that encourages having many children, who then in turn will have many children.

Under this view, one could talk about "infection" with memes.

I'll take "Stupid Things People On Twitter Actually Believe" for 1000 rubles, Alex.

This screenshot getting widely circulated is not from a "Ukrainian government kill list", but rather the website "Миротворець" (Myrotvorets, "Peacemaker"):

uk.wikipedia.org/wiki/%D0%A6%D0…
In case you read Cyrillic, just look at the watermmark on the image in the background:

"Миротворець" (Myrotvorets)

An example Myrotvorets page:
myrotvorets.center/criminal/kobza…
A sort of "OSINT Wikileaks", Myrotvorets was created in 2014 by Roman Zaitsev, a former employee of the SBU in Luhansk oblast, based on an idea from a MoD employee, Matyuha Eduard Andriyovych, to gather intel on people believed to be working against Ukraine for law enforcement.

@elonmusk @EvaFoxU I know you mean well, Elon. But do consider that diplomacy is not simply "find the median between the stances of A and B"

A: I want B's lungs ripped out.
B: No!
C: Okay, rip out ONE of B's lungs.

Also, that public stances != actual goals, that actual goals have to be assessed.
@elonmusk @EvaFoxU War does not end when you find the median between "nominal stated goals", but when parties consider the cost to be too great to continue relative to the benefits.

Evaluating Ukraine here is fairly simple; it's a democracy and you can look at polling.

iri.org/news/iri-ukrai…
@elonmusk @EvaFoxU * MASSIVE assessed negative consequences of a loss - loss of their democracy, their freedom, their culture, their language, and the ethnic cleansing of their people.

* Great confidence in the ability and professionalism in their defenders.

Today in Reykjavík, Ukrainian refugees organized an event to thank Icelanders for their support - starting with the unveiling of a mural. The president of Iceland (guy in the black suit) took part.

І я вперше заговорила українською з українцями :) ImageImageImageImage
Things then moved to Kolaportið . Right near the northern entrance they had a photography display of damage from the war. My favourite, for obvious reasons, being the one at the bottom. ImageImageImageImage
On a different wall they had the winners from a childrens' art contest. ImageImageImageImage

The more I look at @elonmusk's poll the other day, the more one thing bothers me. And it's surprisingly not the astoundingly naive "hold UN supervised elections brutally military-occupied no-tolerance-for-dissent ethnically-cleansed territory".

It's this:
1) It's unabashed Russian propaganda. "Khrushchev's Mistake" is wording practically straight out of Putin's mouth.

edition.cnn.com/2014/03/21/opi…

2) It wouldn't be an excuse *anyway* for brutal militant expansionism and ethnic cleansing.
3) Ukraine was *also* "historically part of Russia" since the 1700s. It *got its freedom back*. Crimeans voted for said freedom - Despite most of the native population having been ethnically cleansed. A population that was since starting to come back when Putin invaded in 2014.
