@cleantechnica Progress

@teslaownersSV @Tesla We’re making progress with Steam integration. Demo probably next month.

@teslaownersSV @cb_doge It’s a flat trade

@EvaFoxU @cb_doge 🤣

@teslaownersSV Autonomous rocket landing on autonomous ship

@cb_doge Actually true. Then I suggested to the team that it didn’t need to be quite so pointy, since that’s just based on a movie joke, but everyone likes it pointy, so we kept it that way.

@BillyM2k @CryptoWhale 😋 bagels

@hohocho If inflation calms down, we can lower prices for cars

Tesla is to protect life on Earth, SpaceX to extend life beyond.

@PPathole 20 to 30 years from first human landing if launch rate growth is exponential. Assumes transferring ~100k each rendezvous and ~1M total people needed.

Mars may be a fixer upper of a planet, but it has great potential!

@tim_ottawa @teslaownersSV Mars is, admittedly, a fixer upper of a planet

@teslaownersSV The scale is 🤯 & anyone can visit!

@waitbutwhy I wonder if there is a species in the Magellanic Clouds wondering who lives in the big galaxy they orbit

@PPathole @Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Some small tubes & wiring need to be nested in a bigger tube for thermal protection, kinda like conduit in a house. Engines themselves & booster base are extremely robust. High strength stainless steel is bulletproof to a handgun at ~2.5mm thickness. Booster dome is 4mm.

@DJSnM @Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Electric power for booster & ship is needed even when engines aren’t running & incremental power draw of TVC isn’t too bad. We have local supercaps on each engine to deal with power spikes.

@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Enabling engines to take the heat without shrouds might save over 10 tons, all things considered. Shrouds are also a risk in that fuel leaks could be contained by the shroud, forming a MOX bomb. Booster is purging all 33 engine shrouds in flight to prevent this.

@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 All mass necessitated by an engine design should count as engine mass, eg shrouds, TVC hydraulic power or excess purge gas. Raptors in production now have electric TVC, saving over a ton of hydraulics mass on booster.
