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_.
Method of choice: electrothermal heating

We did quite a lot with steam rockets. A 50 kN thruster to push around a
car from one of the German premium car builders. They wanted to simulate
side impacts with it. Worked quite well... and yes it was heated
electrically. It needed about half an hour to get the 25 kg water to 250 °C
