Hey Alan

sorry about the long mail i hope this helps

If your talking about decompressing the water to get the gasses out that are 
dissolved in it:
There is a fair amount of oxygen in water however as far as I know there is 
only miniscule amounts of hydrogen dissolved in water. Realistically by far 
not enough of either.

So you are probably talking about electrolysis ? this woks by giving a 
molecule the same amount of energy as it released when its components 
reacted with each other thereby forming the bond(s) that hold it together ? 
the end effect is that you have its components in this case H+H+O (your 
fuel). The obvious problem is WHERE is the energy coming from that is used 
to separate the water in the first place. There are several methords or 
splitting molecules however they all require a potential energy input of 
some kind.

I am going to look for some proven average figures here because there have 
been several different answers to the question. ?how much oxygen dose one 
adult human consume in t?

> has anyone here made there own sonar set up?

It is possible to make your own however there are some very interesting 
products to be found online. The most flexible are probably the emitter 
receiver kits that you plug into a computer. Using the (normally) provided 
software you get a three dimensional view of the readings ? meaning that the 
distances are colour coded (not 3d glasses that allow the image to jump out 
at you !!!(If you find suchlike then pleas tell me))             :)

Some suggestions:

Gas turbine (fuel production)
A good example would be a diesel electric. The sub travels along the surface 
powered by a powerful diesel motor that is also used to power several 
alternators the electricity is then used to power several electrolysis cells 
that produce your fuel. Your fuel is stored in high pressure tanks ready to 
be used by your gas turbine.

Fuel cells:
As far as I know no one on this list has made a fuel cell powered sub. The 
advantages for you would be that in combination with an electric motor they 
are more efficient and cheaper than a gas turbine. If u want a fast sub then 
for example a 1000hp (746kw) electric set up. If you are not familiar with 
this technology then do a search on ?Fuel cells? or wait 20 years then buy a 
car.
             :)
