    We have better rocket fuels which degrade into water vapors.

    Which fuels are those? Also why would one want their rocket fuel to degrade? I can see fuel storage issues with that. Furthermore, keep in mind that the reaction of CH4 and O2 (combustion) creates H2O (water) and CO2. The only fuel that I’m aware of that creates only water when it’s combusted in O2 is H2 (hydrogen). An issue with hydrogen as a fuel, when compared with methane, is its mass ­— lower exhaust mass lowers the specific impulse.
