Time to enrage the muskbot shills via the laws of Thermodynamics...
SpaceX rockets allegedly use 'cold gas thrusters' to orient themselves in the vacuum of space for re-entry:
Okay, now let's see what Thermodynamics has to say about the behaviour of gases in a vacuum, eh?
Hmm - seems that an experiment was done in 1850 proving that a gas does no work when introduced to a vacuum, and that said experiment was one of the foundations of the laws of Thermodynamics...
As Joule himself said, "In this process the gas does not develop mechanical power, i.e. no mechanical work is performed either by or on the gas"
This result is known as Joule, or Free, Expansion:
And it was the basis for the formulation of this gas law:
Work = external Pressure x Change in Volume.
And, as the external Pressure in a vacuum is ZERO, any gas introduced therein will do ZERO work.
Want a definition of Work? Okay:
Zero Work = Zero Force; Zero Force = Zero Motion - FACT.
Yeah, so that's Musk's 'cold gas thrusters' dead in the water ain't it?
Unless he's found a way of defying the laws of Thermodynamics and creating free energy devices...
Anyone think that's likely?
Well, anyone human or sane, that is - bots and psychopaths don't count...
And bots and psychopaths are the only supporters Musk has when it comes down to it.
Edit to include the physics definition of 'vacuum', for the really slow kids at the back of the class:
