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

["C & L Hendkids" <hendkids@oregontrail.net>]

Hello Jürgen,
   I wanted to use a turbine because a propeller does not send out a stream
of very, very hot water, which would leave a wake of dead fish behind...
Turbines would still be necessary to provide electricity. Efficiency,
though, would not be much of a consideration, for as I said before, rockets
provide a tremendous ammt of thrust.
   Do you think that 72 v would be enough to separate hydrogen and oxygen
from H2O? How much energy? At first, I think I would purchase hydrogen and
oxygen to fill fuel tanks, and use some of the power generated (from the
combustion of hydrogen and oxygen) to separate more hydrogen and oxygen.
   Oh, and the hydrogen and oxygen would be liquified...

Thanks,
Alan
