Say that to a Tibetan and I'd like to hear their response when not watched by CCP secret police

Do we need to bring up the list of countries/groups/people that the US government and citizens have done terrible things to?

You could also just use 3-phase AC induction motor.

Tesla actually used 3-phase motors in the past. Their newer motor (not the one in the article) is not a 3-phase induction, but is ~2% more efficient which is important when considering overall vehicle cost/range.

Why this is important: If successful, this contributes towards the reduction of national security risk around rare earth supplies and supply chain located in a possibly unfriendly nation state (major deposits are in Russia and China) and also means you don’t have to establish rare earth mines or supply chains in your own countries (capital and environmental concerns). It’s a big deal! Also, just as newer battery chem…

China is a currency manipulator, human rights abuser, and a non-democratic state. that is a country we have done business with, and looked past, but the US can't be "friends" with terms like that. The relentless anti china propaganda has nothing on the BS that china's state-owned media has said about the US over the last decade. The AVERAGE issue of global times is worse than trump's rhetoric.

Moral judgement in international relations is not a necessity. Please think of other countries that US is allies which with same attributes mentioned in your comments. i.e. Saudi Arabia. I'm not saying that it's right or wrong, what I do mean is there are different rules for engagement between countries than people.

US is a war machine, can drum up support to invade any country even if they're lies, and in the last 300 years, it's hard to find a country that has abused more human rights. The birth of the US coincided with a genocide of native Americans, wars for more land, slavery of an entire people.

And yet, the US actually has allies. After all the crap the US has done, it still has allies. What? Why?

Oh, because it's all about economics and power.

> China is friendly.

As long as you play by their rules which include but are not limited to:

- As a business, living with the likelyhood that any govt forced partnerships with local 'private companies' are a huge risk of IP leakage. Or ghost shifts producing clones of your product. - As a consumer, knowing that their censorship rules impacts(dilutes) media that is now produced for a 'global' audience - As a human being, knowing that they have various prisons that are somewhere between the 'atrocities' the US is finger-pointed at globally and a 're-education' camp in North Korea.

> It's amazing how one Trump presidency and relentless anti-China propaganda in the mass media have convinced Americans that China is not friendly.

OK taking off -all- political glasses and looking at behavior of the populaces.

The world saw how US Citizens reacted for better or worse when told to wear masks.

Compare that to how China deals with Dissidents, or their initial Pandemic response.

Currency manipulation? Do you mean when their central bank is buying dollar assets?

> Tesla plans New content for https://elonmusk.today

Ehh, Tesla just sold their 4 millionth vehicle (waited until then for investor day so they could flex), are breaking ground in Mexico shortly on their new factory, and are rapidly approaching $100B/year in revenue at a 25-30% margin (while other EV startups are teetering near death and legacies are slow to catch up). Constructive skepticism is fine, but strong evidence of their innovation capacity is available (especially around power controls and propulsion, but also structural and environment, such as their heat pumps). Elon’s a liar, but also effective. Both of these things can be true simultaneously.

How much does the alternative increase the weight?

The image from Tesla says "lower cost and higher efficiency drive units using zero rare earths". The "higher efficiency" to me implies that it probably won't be significantly heavier if at all.
