“Engineering is true magic”

“@nichegamer Yezzz”

“@LeilaniMunter @Tesla @HickoryPD @StephenAtHome @cleanairNC @cleanenergyorg @CMPD How bizarre. Sorry to hear that.”

“@nichegamer Putting in little outward-facing speakers would open up a lot of opportunities …”

“Please put “invented car fart” on my gravestone. This is my only request.”

“@Robotbeat @Jon128123 @Diver2441 @Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @alan1bernard Our superalloy foundry is now almost fully operational. This allows rapid iteration on Raptor.”

“@Robotbeat @Jon128123 @Diver2441 @Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @alan1bernard SpaceX metallurgy team developed SX500 superalloy for 12000 psi, hot oxygen-rich gas. It was hard. Almost any metal turns into a flare in those conditions.”

“@BENBALLER Thanks!”

“@Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @Robotbeat @alan1bernard It’s embarrassing that Boeing/Lockheed need to use a Russian engine on Atlas, but that engine design is brilliant”

“@Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @Robotbeat @alan1bernard You def don’t want electric pumps on a rocket engine! Raptor turbopumps alone need 100,000 horsepower per engine. That’s not a typo.”

“@Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @Robotbeat @alan1bernard Yes, full flow, gas-gas, staged combustion. Will take us time to work up to 300 bar. That is a mad level.”

“@NASASpaceflight @_Synders @John_Gardi @martinengwicht @Erdayastronaut @JeromeJaccard @Robotbeat @alan1bernard Yes. Radically redesigned Raptor ready to fire next month.”

“@Erdayastronaut @ludan27 @JeromeJaccard @Robotbeat @alan1bernard Seriously! We are just on the wrong planet for SSTO. Mars, no problem.”

“@_Synders @John_Gardi @martinengwicht @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard Starlink V1 on Falcon, V2+ on Starship. Basically, all future products will contain either the word “star” or “link” 😀”

“@ludan27 @Erdayastronaut @JeromeJaccard @Robotbeat @alan1bernard Yes, but single stage to orbit with no payload is pointless. Add Super Heavy rocket booster & orbital payload is gigantic. Only need booster on Earth, due to deep gravity well & thick atmosphere. Starship alone on moons & Mars.”

“@John_Gardi @martinengwicht @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard Coldformed at cryo”

“@Malcolmmarsman @TheMuddySchmuck @martinengwicht @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard This test hopper is at full body diameter of 9m / 30 ft, just not full height. Super Heavy will be full height & diameter.”

“@thescalex @Jonas123denmark @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard Exactly”

“@martinengwicht @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard For sheet/plate, at supplier made to our spec. For cast, in our Hawthorne foundry.”

“@johnkrausphotos @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard Yes”

“@Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard I will do a full technical presentation of Starship after the test vehicle we’re building in Texas flies, so hopefully March/April”

“@Erdayastronaut @JeromeJaccard @Robotbeat @alan1bernard While there are some material similarities, Starship is very different from the Atlas design”

“@Erdayastronaut @JeromeJaccard @Robotbeat @alan1bernard Stainless steel is correct, but different mixture of alloys & new architecture. Unlike Atlas, Starship is buckling stable on launchpad even when unpressurized.”

“@wangmeister If Tesla committed delivery & customer made good faith efforts to receive before year end, Tesla will cover the tax credit difference”

“@wangmeister It will be tight, but Tesla production should have all mid-range Model 3 orders delivered by year end”

“@MikeKasprzik @Tesla Try connecting to WiFi”

“Tesla has released all cars for sale where original customer can’t take delivery before year end, as well as test drive / display cars, which cost less. Reminder to US buyers that $7500 tax credit drops in half in 8 days. Order online at https://t.co/46TXqRrsdr or visit stores. http://Tesla.com”

“@quantumVerd @QuilletteM @pewdiepie Only if Dawkins joins”

“@QuilletteM Interesting”

“@Shedletsky 👌”

“💛 Bajirao Mastani 💛 https://t.co/XbmDpiyfOP https://t.co/DZyV6S7TJZ https://m.youtube.com/watch?v=h6lHUn20J5g”

“Anxiety is a scalar, fear is a vector”

“@chrinder Haha”

“@WWERollins Namaste 🙏”

“@Taraustralis Needs a warmup”

“@Space_Station @AstroAnnimal @Astro_DavidS Must feel amazing up there in microgravity zooming around the Earth every 90 minutes! Hope you have a Merry Christmas!”

“@JohnKasich Thanks, will consider next year”

“@nichegamer @boringcompany So long as the tunnels are spaced about one diameter apart, most of the stress will flow around them, but this won’t matter for the first few layers”

“Tesla phone app release next week will enable service scheduling in 2 mins with a few taps. No more need to call!”

“@wolfejosh 😴”

“@Itsjoeco @wolfejosh 💨”

“@wolfejosh 💨”

“As a thank you to Tesla short sellers, we named a 💨 after them haha https://t.co/5GCgM4RT4W https://techcrunch.com/2018/12/19/listen-to-a-tesla-make-6-farting-noises-on-demand/”

“@c7five @Jaku 👍”

“Perhaps lost in the transport debate is that @boringcompany built a 6000 ft tunnel in LA for ~$10M with V1 (Godot). Next tunnel will be made with V2 (Line-Storm). V3 (Prufrock), aspirationally 10X better, should be operational next year.

“Join our underground movement!”

“@DeadstockNYC Reverse back down (using same roller guide wheels, so no skill required) & tow or flatbed it out”

“@vicentes @Attack @Tesla Ok 😀💨”

“@EcoHeliGuy @Erdayastronaut @martinengwicht @realkrauswife @Tesla Autopilot doesn’t need the guide wheels. They’re only there if there is a complete system failure. Turns will definitely be banked in future.”
