I know this is way off-topic, but it has always had me wondering and it seems like Arocket has the appropriate knowledge base to address this (or, at least wildly speculate). In some of Larry Niven's sci-fi stories, he imagines rocket thrusters (between the ground and orbit) based on super-compressed air (supposedly "nearly degenerate matter"). Would such thrusters theoretically work, or are there some thermodynamic (or other physics) limitations that come into play? Thanks, Robert
