I think what you are looking for is the decomposition of hydrogen peroxide.
90% H2O2/NaMnO4 yields 600 degree steam plus O2. Germans used it in various
applications during WW2. The reaction was used in the V2 to drive the turbo
pumps. Regards,Barry Jolly Sent from my Sprint Tablet.

I have reviewed the patent and it is only for the "design" of a propulsion
unit. Although some chemicals
are listed, they may or may not have really been used by them because the
chemicals are not what is
being patented. I have run some combinations of these chemicals thru a
chemical equation solver and
no results have been encouraging so far, but I will try a bunch more before I
conclude that these chemicals
may not actually be the ones that were used.
