Yes. They won't work because they operate on a difference in air pressure providing a force. No air? No force. Same reason an airplane wing won't provide lift in the upper atmosphere.
But, compare to a rocket engine that does NOT need an atmosphere to push against.
Dear ladies and gentleman of the jury. I will now argue that the LLM that programmed the fire breathing dog, did so in such a manner as to make it sentient. The dog was able to and did act of it's own accord when it killed the woman, Ms Smith. The defendant here did not create sentience in the dog, nor could he have known turning the dog on, outside, may result in the fire breathing dog torch a bystander to death.
You can see here, the dogs walking and urination patterns closely align with a real, organic dog. This definitively proves that the dog killed the woman, and now the defendant, who only released the dog into nature. Thank you very much.
