When Sandy Munro mocked up 4680 cells in a $TSLA 3/Y pack, he said it should unprecedented rigidity:

That would be like licensing Battlestar Galactica. Actually building continuously evolving gargantuan factories is the hard part. Lots of people who worked at Tesla Gigafactories now work at competitors, but none of those companies have made one.

And the beautiful thing is each gigafactory is like a new product and is better than the prior

Yes, the Gigafactory is the hardest & most critical product

Will Giga Berlin stamp the middle of the main body as one piece as well?
Elon Musk
@elonmusk · Oct 7, 2020
Battery pack will be a bonded structure with cells providing shear transfer between steel upper & lower face sheets, eliminating most of the center body parts while providing better torsional rigidity & improved polar moment or inertia. This is a *major* breakthrough.

Even GM & Chrysler went bankrupt in 2009. Ford and Tesla are the only US car companies that have avoided bankruptcy.
Elon Musk

But now we understand production much better. It will be our primary competitive advantage long-term.

The Model 3 production ramp was sheer agony for two years, but that was do or die for Tesla. No US car company has reached high volume production with sustained free cash flow in ~100 years. Hundreds of car startups all died or were absorbed for peanuts by big three.

How do you view this risk as difficult but better than m3 ramp? I don’t want to see you go through that kind of pain again.

“Large scale manufacturing, especially of new technology, is somewhere between 1,000% and 10,000% harder than the prototype. I would really regard, at this point, prototypes as a trivial joke," — @elonmusk
Elon Musk
@elonmusk · Oct 7, 2020
Bringing a new product to volume production is 1% inspiration & 99% perspiration. You do still need that critical seed of inspiration, but it’s fun & takes ~100 people. Production takes >10,000 people & hurts like hell until the gigantic cybernetic collective runs smoothly.

Interesting to see Momentus and Rocket Lab take unique approaches to meet small satellite demand.
Momentus with "last mile" orbit delivery.
Rocket Lab with small rockets.

Marginal cost of Starship mass to orbit should be well under $100/kg. Fully burdened cost depends on flight rate.

Elon Musk
@elonmusk · Oct 7, 2020
Prototypes are a piece of cake, but high volume production of a new technology is extremely hard. Takes much longer than people think to climb the production S-curve. I can’t emphasize enough that production is by *far* the hard part.

Berlin will use 4680 cell with structural battery pack & front & rear single piece castings. Also, a new paint system.
Lot of new technology will happen in Berlin, which means significant production risk. Fremont & Shanghai will transition in ~2 years when new tech is proven.

hey, what kind of cells are you planning to move our hearts with in Berlin?
CATL LFP? 2170 cells... 4680? I know you said you’re making cells in berlin

It's funny. When you watch Daimler & Tesla investor presentations, you can really see the difference between the two companies
Daimler's CEO talks about the company like it's a spreadsheet
But @elonmusk and Drew talk about engineering and products
I know which I'm investing in
Elon Musk
@elonmusk · Oct 7, 2020
I do so wish that more companies would put down their spreadsheets for a moment and focus on making products that move your heart

What bar strength did it reach? 🚀
Elon Musk
@elonmusk · Oct 7, 2020
7 bar absolute, which is fine for flight. This was a proof test, rather than a burst test. We’ll hopefully fix the leak today & retest.

Cryo pressure test succeeded, but a small leak opened up near the engine mounts, possibly due to differential shrinking
