That's pretty neat. The rocket was used to figure out car dynamics in a
side collision without actually colliding with anything. Looks like this
was on of those superheated water-to-steam rockets. Right?
Would you mind if I shared this with the Apex Automotor Facebook group? I
think they would get a kick out of seeing this...
Thanks,
Robert

Elon should talk with us ;-) We built a 50kN (11200 lbf) hot water rocket
into a BMW for side impact simulations. Thrust was adjustable via water temp
(And therefore pressure) and impulse via opening time of the valve (Which
had a huge opening of about 90mm which can be opened and closed in
milliseconds)

Tesla appears to be planning some sort of cold gas thruster option for
their new roadster model
See
https://insideevs.com/news/350682/tesla-roadster-spacex-thrusters/ for
example
but I cant find anything definitive about what these thrusters are
planned to look like. On one car enthusiast Facebook group I
subscribe to, someone was claiming that Tesla was planning to put ten
400 lb thrusters around the vehicle which would be capable of firing
for 90 seconds, which sounds silly just thinking about the mass of
nitrogen required.
Does anyone here have any information/informed-speculation they could
share about these potential Tesla thrusters?
Thanks,
Robert
