Back in the 1960s, I worked out a steam rocket, based an H oxygen
cylinder almost full of water. The only thing I remember after all
this time was the estimate that it would reach 20,000 feet. (This
might be wrong, and no, I am not going to reconstruct the math.)
The design was an H cylinder in a launch cradle with a bunch of
_propane heaters_.
