“@marstronauts @Erdayastronaut @JaneidyEve @13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @SpaceX Vacuum nozzle engines are only used in (near) vacuum conditions. Sea level engines need to gimbal rapidly & at high angle for landing. Larger nozzle leaves less room to move & increases moment of inertia.”

“@Erdayastronaut @JaneidyEve @13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @SpaceX Yeah. Outer engines with much larger nozzles are fixed to airframe, inner engines have high gimbal range ~15 degrees”
“@tommleach @trigomemetry https://t.co/ViY0WgtfOZ”
“@trigomemetry Sure”
“@DirkSmit76 Two tunnels about a mile long each”
“@Debapratim15 @curiousmind44 @SPEXcast @13ericralph31 @JaneidyEve @bluemoondance74 @Orion_Sword @Some1gee @Erdayastronaut @SpaceX @JeffBezos Yes”
“@curiousmind44 @SPEXcast @13ericralph31 @JaneidyEve @bluemoondance74 @Orion_Sword @Some1gee @Erdayastronaut @SpaceX @JeffBezos Makes no sense. In order to grow the colony, you’d have to transport vast amounts of mass from planets/moons/asteroids. Would be like trying to build the USA in the middle of the Atlantic Ocean!”
“@_ishanspatil @SPEXcast @13ericralph31 @JaneidyEve @bluemoondance74 @Orion_Sword @Some1gee @Erdayastronaut @SpaceX Aiming for 150 tons useful load in fully reusable configuration, but should be at least 100 tons, allowing for mass growth”
“@SPEXcast @13ericralph31 @JaneidyEve @bluemoondance74 @Orion_Sword @Some1gee @Erdayastronaut @SpaceX N2 for vacuum. Aero surfaces & high gimbal angle main engines for atmosphere.”
“@SPEXcast @13ericralph31 @JaneidyEve @bluemoondance74 @Orion_Sword @Some1gee @Erdayastronaut @SpaceX Hoping for 380 sec Isp, but at least 370. Otherwise similar to sea level version.”
“@13ericralph31 @JaneidyEve @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @Erdayastronaut @SpaceX Aspirationally”
“@JaneidyEve @13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @Erdayastronaut @SpaceX 3 sea level optimized Raptors, 3 vacuum optimized Raptors (big nozzle)”
“@13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @Erdayastronaut @SpaceX After the GoT finale, we dropped it to 6”
“@SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @Erdayastronaut @SpaceX Mk1 & Mk2 ships at Boca & Cape will fly with at least 3 engines, maybe all 6”
“@bluemoondance74 @Orion_Sword @Some1gee @Erdayastronaut @SpaceX About to complete SN5, ramping to an engine every 3 days this summer”
“Boring Company starts digging Vegas tunnel in 2 months. Aiming to finish by end of year.”
“@Orion_Sword @Some1gee @Erdayastronaut @SpaceX The turbine also spins though. Partially combusted gas drives the turbine wheel, which is attached to a shaft that turns the inducer & impellers.”
“@Orion_Sword @Some1gee @Erdayastronaut @SpaceX But, essentially, the spinning things”
“@Some1gee @Erdayastronaut @SpaceX Yes”
“@Erdayastronaut @SpaceX Turbopump propellant flow path to achieve high chamber pressure is quite tricky. Requires an inducer & 2 impellers with ~100,000 shaft horsepower.”
“😉”
“@royalacademy @guardian @FT @Telegraph Did it for the memes https://t.co/jVnidsSJmj”
“@teslainventory Coming soon”
“@arctechinc @Everman @cleantechnica Yeah, been thinking about it for a long time. Electric supersonic VTOL. Hard problem.”
“@BPSYT1 @Erdayastronaut @SpaceX Hopefully in about 10 days”
“@Erdayastronaut @SpaceX Physics favors full flow”
“@cleantechnica Good design imo”
“@sama Thanks Sam!”
“@ARKInvest Good piece on lower total cost of ownership of electric vehicles”
“@Erik2be @Teslarati Sorry to hear that. Will fix.”
“@Liv_Boeree Ok”
“@PunishedFranc83 @SpaceXStarlink @SpaceX Easy to turn one of our Starlink satellites into a debris collector”
“@PunishedFranc83 @SpaceXStarlink @SpaceX Yes”
“@giarC71 Almost ready. I’m testing it personally this weekend.”
“@gurleen_s_ Yes”
“Also porting Unreal Engine”
“@FHiedra Nintendo won’t let us”
“@BillM_HB Maybe so eventually, but it will be information & entertainment, not trickery”
“Tesla does not advertise or pay for endorsements. Instead, we use that money to make the product great.”
“We def need racing game using actual car steering wheel & pedals!”
“@juanittoburrito @sargentwhitey Of course”
“@GlamandGore Portal 1 & 2 on this would rock”
“@asimo3089 @Roblox Would be great to have @Roblox & @Minecraft!”
“Interact with games via touchscreen, steering wheel buttons & XBox/PS controllers”
“Lots more games coming once we finish porting Unity!”
“@flcnhvy Top Secret https://t.co/Gi2wN2HVyO”
“@MillShive @ChrisG_NSF @jdeshetler It technically could, but wouldn’t have enough mass margin for a heat shield, landing propellant or legs, so not reusable”
“@MyCatNameIsShad No worse than production of a gasoline car, provided the lithium-ion battery cathode is primarily nickel vs cobalt. Nickel is the main alloying ingredient in stainless steel, which is what knives & forks are made of.”

“Because a Tesla produces no emissions & filters most toxins, pollen, spores & viruses, it actually cleans up surrounding air as it travels”
