Isothermal LOX and propane tanks allow the propane density to rise
to 728 kg/m3, approaching the density of kerosene with nearly the

hazards, too.
I note that the gap between the boiling point of LOX and the melting
point of propane is quite narrow, less than 5 degrees C. Does this
cause any problems in practice? It certainly would mean you couldn't
use subcooled LOX for increased density.
