Spaced,
You might also look up "Perhydrol" and "Walter Cycle". The Germans used Perhydrol aka HTP and diesel as the fuel in several submarines powered by steam turbines (developed from the V2/A4 rocket turbines) - an idea followed up by the Royal Navy in two subs, HMS Experiment & Excalibur. They were both abandoned owing to too hot conditions in the engine room (not because the system didn't work) - makes you wonder what simple computer control could do.
