@alex_avoigt Yeah

@markpinc Not this time

@markpinc Open borders is madness

@tunguz The rate of increase of AI is 🤯

@BasedBeffJezos @lexfridman Sounds extremely esoteric now, but it won’t in the future

@BasedBeffJezos I hope not, but there is a small chance it may be necessary

@paulg Yeah. The team put in a staggering amount of work to get to Raptor 3.

@alifarhat79 Seriously

Model 3 Performance version is 🔥🔥

@WholeMarsBlog Other companies dumping EVs at massive negative gross margin is a problem, but not one that will last

@ajtourville Exactly

@farzyness @TeslaLarry @HansCNelson That guy doesn’t get it. I would prefer to have zero involvement in politics. HOWEVER There is no “company success” unless civilization itself continues to progress. This insane shift by the “left” away from a meritocracy and personal liberties (eg censorship of free speech

@ajtourville Yeah

Just did a walkthrough of the Tesla supercompute cluster at Giga Texas (aka Cortex). This will be ~100k H100/H200 with massive storage for video training of FSD & Optimus. Great work by the Tesla team!

@FutureJurvetson @SpaceX Indeed. It is not widely understood that SpaceX has the most advanced 3D metal printing technology in the world.

@SpaceX In a few years, we will finally have a Raptor 3/4 vacuum version (giant nozzle) that has an Isp of 380

Worth it

@SpaceX Important to note that the induced mass (mass required by a given engine design that is not the engine itself) of Raptor 3, while far better than Raptor 2, still has a lot of room for improvement. Thrust will exceed 300 tons with Raptor 3.x (thrust/mass>200), enabling 10,000

@myhiddenvalue Is this for real? @CommunityNotes

@SmallPettingZoo @Rob_2628 Same (groan)

@alex_avoigt Cool

Starlink now available in 102 countries!

@ajtourville The fundamental architecture is now right, but we will still make thousands of improvements

@ajtourville Many of them are 3D metal printed into the wall of the part

Interesting

@Erdayastronaut And it no longer requires a heat shield. Everything is regeneratively cooled.

@Erdayastronaut It really is

The amount of work required to simplify the Raptor engine, internalize secondary flow paths and add regenerative cooling for exposed components was staggering. As a result Raptor 3 doesn’t require any heat shield, eliminating heat shield mass & complexity, as well as the fire

@hoovlet Detailed explanation

@tsarnick Yeah
