@TeslaGong @TeslaTested Yes

@ICannot_Enough @TeslaTested Autopilot team is making great progress. Reality sure is complicated!

@ErcXspace @MarcusHouseGame @brendan2908 @BocaChicaGal @NASASpaceflight Aspiring to have no flame diverter in Boca, but this could turn out to be a mistake

@eugenelee3 @MarcusHouseGame @brendan2908 @BocaChicaGal @NASASpaceflight We do have giant steel balls haha

@TeslaTested We just completed a financing round, but will let you know when there is another one

@IheartTesla @alex_avoigt @mike_zimon @WholeMarsBlog I definitely need to try these tasty cakes & pastries on my next visit!

@MarcusHouseGame @brendan2908 @BocaChicaGal @NASASpaceflight Mass ratio. Liquid oxygen is much denser than liquid methane, even when the latter is cooled to just above its freezing point.

@IheartTesla @alex_avoigt @mike_zimon @WholeMarsBlog Had the most amazing kebab ever just outside of Tacheles. Too bad that place got torn down. It was awesome.

@IheartTesla @alex_avoigt @mike_zimon @WholeMarsBlog döner kebab

@TribeHoh @SpaceX @WAStateCommerce You’re most welcome!

@brendan2908 @BocaChicaGal @NASASpaceflight High bay should be finished (except for the giant gantry crane) within a few weeks. Super Heavy stacking should begin around then.

@alex_avoigt @mike_zimon @WholeMarsBlog That looks tasty!

@tesladri @ChananBos @raytech247 @WholeMarsBlog The crash absorption rails can be cut off & replaced with a bolted part for collision repair

@ICannot_Enough @WholeMarsBlog Sandy Munro understands engineering

@flcnhvy @teslaownersSV @raytech247 @WholeMarsBlog 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.

@teslaownersSV @raytech247 @WholeMarsBlog Yes, the Gigafactory is the hardest & most critical product

@ChananBos @raytech247 @WholeMarsBlog 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.

@raytech247 @WholeMarsBlog But now we understand production much better. It will be our primary competitive advantage long-term.

@raytech247 @WholeMarsBlog Even GM & Chrysler went bankrupt in 2009. Ford and Tesla are the only US car companies that have avoided bankruptcy.

@raytech247 @WholeMarsBlog 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.

@EvaFoxU @WholeMarsBlog 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.

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

@WholeMarsBlog 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.

@WholeMarsBlog We do expect to make heavy use of LFP for medium range cars & stationary storage

@WholeMarsBlog 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.

@AstroJordy @WholeMarsBlog They are

@WholeMarsBlog I do so wish that more companies would put down their spreadsheets for a moment and focus on making products that move your heart

@PPathole @klod_ua @Erdayastronaut @TrevorMahlmann @johnkrausphotos @Mike_Seeley 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.

@klod_ua @Erdayastronaut @TrevorMahlmann @johnkrausphotos @Mike_Seeley Cryo pressure test succeeded, but a small leak opened up near the engine mounts, possibly due to differential shrinking

@Erdayastronaut @TrevorMahlmann @johnkrausphotos @Mike_Seeley One of the best shots ever!

@SamTalksTesla @SpaceX Much sooner
