RT @TrungTPhan: Tesla VP of Hardware Engineering Lars Moravy explains to Hagerty how the Roadster borrows SpaceX cold gas thrusters to make 0 to 60 possible in 0.55 seconds. Truly insane: ▫️ 200L carbon-over wrapped pressure vessel behind seat holds nitrogen at 10,000 PSI ▫️cold gas thrusters push out 80 kN of thrust (equivalent to a single fighter jet engine) ▫️Tesla went with nitrogen because “it just seemed wrong to put fuel into a car” (air is ~80% nitrogen, fair enough) ▫️thrusters same system satellites use to move in space (eg. the “psh psh psh" from Apollo 13 film) ▫️currently takes 6 to 7 hours to refill all nitrogen but Tesla working for it to be 30 minutes ▫️uses leg actuators from Optimus robot to manage downforce on wing *** Full 25-min episode with Henry Catchpole here: https://youtu.be/22rvpUecLts?si=jtwK4t58kotdGkyi
