[QUOTE="Umbran, post: 6166804, member: 177"] Most of science fiction is based off of taking current science, moving into a place where it is fantastic, and asking, "What if?" Application of logic like this is how science fiction happens, Morrus. If you don't find anything valuable in the exercise, that's fine. But could you stop raining on the parade, please? A terrestrial creature breathes to do two things - bring in a chemical agent that makes its metabolic processes work, and expel the results of those processes. Nitrogen is neither a strong oxidator, nor a strong reducer. It does not stand well at all as a part of a chemical energy metabolism. While you can build energetic metabolisms on other gases, what we have is oxygen. Unless it is carrying a huge tank of some other agent, that's what it has to work with, so it better at least be able to use the oxygen, or not need to breathe at all. If you want us to stay with normal physics, this is not possible. Thermodynamics requires there be waste. No process is 100% efficient. [/QUOTE]
