The only harm that could do is burn and melt pedestrians faces and add a ton of extra weight to the car. Rockets are the worst way to get up into the air, unless you want to go to space or be speedy and fast. Propellors are way better for these kinds of tasks.

sh1pman Posted June 9, 2018 Share Posted June 9, 2018 Guys. Forget chemical thrusters, this is Tesla. Looks like they finally made it work. Quote Link to comment Share on other sites More sharing options...

Rockets are the worst way to get up into the air, unless you want to go to space or be speedy and fast. Propellors are way better for these kinds of tasks. Rockets are even worse than that. Pretty much the only reason they are used involves lack of reuse and/or 99% of the trip requires rockets and there are too few trips to justify designing a more efficient non-rocket stage. Spaceship 1 had *tiny* delta-v requirements (compared to any other space mission) and they still designed an entirely custom non-rocket stage 1. - that might have been in Burt Rutan's contract. You'd think an extremely used 747 would have been cheaper (perhaps designing the White Knight was cheaper than the legal challenges pointing out all the 747's subsidies).

sevenperforce Posted June 10, 2018 Share Posted June 10, 2018 13 hours ago, Ultimate Steve said: I really hope they use something other than Hydrazine. In a subsequent tweet, the implication was that they'd pack a COPV full of compressed nitrogen and refill it periodically with an electric pump. So the car would have cold-gas thrusters, not combustion rockets. Might give you a nasty case of frostbite if you put your hand in front of it, but no worse than putting your hand in front of a gas-auto tailpipe. I mean...yeah, this actually would work. If the cold gas thrusters have enough kick it COULD really help with cornering, takeoff, and so forth. Quote Link to comment Share on other sites More sharing options...
hms_warrior Posted June 10, 2018 Share Posted June 10, 2018 (edited) but...why? There is nothing to gain for a car by having rockets. Sorry don't buy it. It's a Joke. (Or he is actualy going to release that they going to build electric votl planes...that could be interpreted as a tesla with rockets^^) Edited June 10, 2018 by hms_warrior Quote Link to comment Share on other sites More sharing options...

Mad Rocket Scientist Posted June 10, 2018 Share Posted June 10, 2018 Looking like the rocket powered tesla is for real. Use this link to read all of Elon Musk's tweets and replies without a twitter account: https://twitter.com/search?f=tweets&vertical=default&q=from%3Aelonmusk&src=typd This was posted on reddit, it seems to be a similar concept: Quote Link to comment Share on other sites More sharing options...

Wjolcz Posted June 10, 2018 Share Posted June 10, 2018 (edited) Whaaaaaaaaaaaaa...? I'm guessing that 'RCS' Tesla system will be mainly used by autopilot to brake. I'd imagine that since the next model is going to have crazy fast acceleration slowing down from such speeds will be problematic. So basically manned MKV with wheels.

Canopus Posted June 10, 2018 Share Posted June 10, 2018 Maybe they should focus on getting the Autopilot to work reliably before equipping it with compressed gas blasters? Quote Link to comment Share on other sites More sharing options...
