Re: [PSUBS-MAILIST] Rocket powered submarine, etc

[Juergen Guerrero Kommritz <groplias2@yahoo.com>]

Hello Alan
The idea of a rocket submarine is nice.  But why you
want to use a turbine?  The most eficient system is to
inject steam directly in the water.  As far as I know
the most eficient system of boat propulsion is a steam
injector you use the presure of steam and also the
fact that steam condense in water so it create an
underpresue and so you can provide trust.  With a
rocket you will get enought presure to compensate the
deep presure. It is an interesting idea.
The problem is to get the fuel.  You need a lot of
enery to produce Hydrogen and Oxigen from water  at
1600° C water split into its elemnts but you need a
lot of energy for that.
I hope this help.
Best wishes
Jürgen
