Ralph J. Somerby, inventor and engineer, built this highly experimental (and highly dangerous) solo steam
rocket. The simple design consist of a nozzle to direct steam in a large blast radius using a custom diffuser.
Above the steam nozzle is a basic structure to hold the steam tank and the operators seat.  The operator has
a simple valve mechanism which allows for a somewhat gradual releasing of steam out the diffuser and steam
nozzle. The steam tank must be filled on the ground before flight.  There are two gauges giving both the
filling operator a good view of the current state of pressure along with the operator while sitting in his
seat (blue and white gauge respectively). Due to the location of the steam nozzle and the operator seat the
rocket has a tendency to drift towards the port side. This drift could be fixed by more parts to help direct
the steam. But further attempts to tweak this design were dropped after his wife discouraged further "playing
with such dangerous machinery".
