Rest in peace Syd Mead. Your art will endure.

@kulpability @cleantechnica C tbh

@John_Gardi @Erdayastronaut Many ways to solve this problem, but the power requirements are much higher than aircraft control surfaces. When moving giant body flaps rapidly, achieving high power is much harder than high torque.

@ShaneAppleton7 @Erdayastronaut Building prototypes is relatively easy, volume production is hard

@JaneidyEve Headed to Tesla Fremont factory tomorrow to help with vehicle deliveries

@EvaFoxU Biting off more than I can chew. Because I’m an optimistic fool.

@Teslarati Hard to believe it’s almost time to retire Cargo Dragon after a decade of solid service

@BaconMan65 @PhiliChez Exactly

@cleantechnica Will talk about that on Q4 call

@EverydayTesla Yeah, engineering is ~90% of my time at SpaceX & about ~60% at Tesla

Barrel on dome https://t.co/kpSIJphbnk

@ajtourville @cleantechnica Took me an embarrassingly long time to learn that

@SteveHamel16 @cleantechnica Sounds about right 🤣🤣

@DonaldM38768041 @Erdayastronaut Beyond awesome. He was the real deal.

@cleantechnica Seems so long ago

@Erdayastronaut Yes

@cleantechnica Also, I hate deeply nested classes in C++. Had to be said.

@cleantechnica The less code, the better! 1 point for adding a line of code, but 2 points for deleting a line. Bloatware is the devil.

@Erdayastronaut Direct drive using several Tesla Plaid motors in parallel for SN1. Simpler, lighter & more fault tolerant. Rear flaps each need ~1.5 megawatts. It’s like moving the entire wing of an aircraft!

@TeslaGong @BrianGilbert_ @Tesla @AusTeslaOwners Tesla merch def needs some love, but too many fish to fry rn

@TeslaGong @BrianGilbert_ @Tesla @AusTeslaOwners Coming …

@ajtourville @Erdayastronaut Tesla uses that to wirebond cells to module current collectors. Is there a commercially available machine that can weld ~4mm full hard 301 stainless barrels & domes?

@Kristennetten @SmileSimplify @Erdayastronaut We’re focusing on Boca right now for Starship & Cape is focused on Falcon/Dragon

@Erdayastronaut Spin start from COPVs so the ox & fuel turbines spool up super fast in unison. A precise start with full flow staged combustion is very important.

@SmileSimplify @Erdayastronaut Moving to an enclosed (fairly) clean room environment for SN2 in Jan, although, unlike aluminum, stainless steel welding is not super sensitive. Our main issue here in Boca is that it can get very windy, which affects weld arc & steel melt pool.

@Erdayastronaut No, will be autogenous from the start, tapping hot CH4 & O2 from Raptor

@teslaownersSV @TonyCrisostomo @Erdayastronaut Yeah

@Erdayastronaut Best would probably be an autogenous laser weld, but we need more precise parts & fixtures. Hopefully get that done in 2020.

@Erdayastronaut Almost everything is different. These parts are stamped vs manually bump-formed & TIP TIG welded vs flux core. Higher precision, stronger joints & 20% mass reduction.

@DJSnM We use that process for the Raptor nozzle jacket. The knuckles of this dome are stamped in Michigan with a 4000 ton car body press, which costs much less for same outcome.

Almost three now. Boca team is crushing it! Starship has giant dome 🤣🤣 https://t.co/qTN2TU02pb

@donnyraywoody @flcnhvy @kulpability @NASA Haha true

@flcnhvy muffin or not-muffin

@realRickyReeves @Erdayastronaut @NASA Crew Dragon is capable of propulsive landing, but would require extensive testing to prove safety. Better to focus on Starship.

@kulpability @NASA New technology development schedules tend to exhibit a version of Zeno’s Paradox — at any given point, you’re halfway there

@kulpability @NASA Crew Dragon should be physically ready & at the Cape in Feb, but completing all safety reviews will probably take a few more months

Simulation of first crewed flight of Falcon 9 / Dragon 2020 @NASA https://t.co/BSDPYTcVIG

8 years later, the simulation is mostly real

@vincent13031925 @Tesla @jsrdctz Amazing work by Tesla China team!! ❤️❤️

@28delayslater 🤣🤣

@BrianGilbert_ @Tesla @AusTeslaOwners Tesla app based payment will soon be rolled out WW. It’s tough making functionality work across so many regulatory domains.

@BrianGilbert_ @Tesla @AusTeslaOwners Is purchasing through the Tesla app not working?

@teslaownersSV @iam_preethi I def believe in the ethical treatment of animals & taking action of climate, but these are mostly separate moral issues

@EvaFoxU @TeslaHistorian @TeslaOwnersofMA @JohnnaCrider1 @vincent13031925 @boringcompany Nice

@teslaownersSV @iam_preethi Renewable energy production (solar, wind, geothermal), improving home insulation & electric transport will do the trick. Vegan/vegetarian helps a little, but isn’t critical. We should take the set of actions that maximize total public happiness!

@ingmutw @iam_preethi @Tesla Ok

@iam_preethi I support people choosing whatever diet makes them happy, but it’s true that everyone going vegan still wouldn’t stop climate change. Moving billions of tons of hydrocarbons from deep underground into the atmosphere & oceans is fundamentally the issue.
