<DIV class=yiv1125570141y_msg_container><BR>I've been following this
discussion with great interest. I don't have a <BR clear=none>sub yet,
but I do live in the Tropics, and as there's no cold current <BR
clear=none>handy to where I live any subbing I do will be in water
pretty near air <BR clear=none>temperature. As you might expect, I've
given this problem a lot of thought.<BR clear=none><BR clear=none>My
tentative conclusion is that, if I build a sub, I will have to make <BR
clear=none>it more autonomous than is the rule on this list.
Specifically, it will <BR clear=none>need a combustion engine to ferry
itself on the surface to dive sites, <BR clear=none>and to maintain
comfort and keep the battery topped off for diving while <BR
clear=none>doing so. I started with the assumption that I would need an
air <BR clear=none>conditioning unit running off a small industrial
diesel, but then I <BR clear=none>realized that, if I use a snorkel
exhausting into
the cabin, and have <BR clear=none>the diesel draw air from the cabin,
I get continuous renewal of the air <BR clear=none>in the cabin without
the cost, power burden and safety problems of <BR clear=none>running a
Rankine cycle refrigeration system. That's the solution that <BR
clear=none>I've retained for the moment. Of course I also need a secure
means of <BR clear=none>preventing exhaust gas from being aspirated into
the snorkel (I can't <BR clear=none>quite understand how naval
submarines manage to combine both functions <BR clear=none>in one mast),
but that might be as simple as having the diesel exhaust <BR
clear=none>flush with the hull, with some arrangement to prevent water
from coming <BR clear=none>in. Since the diesel would only be used on
the surface, and the snort <BR clear=none>would only be there to allow a
low-freeboard hatch to be kept closed, <BR clear=none>the power penalty
would be minimal.<BR clear=none><BR clear=none>Fuel storage,
fuel feed and the like still have to be worked out. Naval <BR
clear=none>submarines have very complex arrangements for this, and that
complexity <BR clear=none>must be tolerated for a good reason. Even so,
I need a simpler way to do <BR clear=none>it that still protects the
fuel from contamination and me from asphyxiation.<BR clear=none><BR
