James,
Permanently mounted exterior solar panels
for subs rated for a range of depths, is a very big challenge I've only begun to
explore. There are all sorts of new solar panels designs coming out these days,
and it's tough to keep track of them all, whether they work, and whether they
are in mass production yet. The designs are getting more and more
efficient as well. So to begin to answer your question, I would say you should
have as much square footage of the most efficient panels you can acquire, that
can be submerged to the depth specs of your sub and that don't cause to much
drag or to much of an entanglement hazard. I've heard about a
couple different designs that you can walk on and that can conform to the
surface shape of the subs hull.
Your idea of a retractable deck gave me
all sorts of ideas for how that could work. I'm a big proponent of having
allot of deck space on a large recreational submarine. So that is one of the
reasons I like a trimaran design. For retractable designs you could start
with some sort of slide out design of the top area of the sub. Much like on a
motor home. This would of course effect stability in a single hull sub, so
that will have to be planned for.
The German Type 212A is a interesting
design. What if you tweaked it a bit and made the bow into a plumb bow, like a
wave piercing boat design. This way you have more control while submerged, and
learn the lesson Peter learned with Kraka.

Brent

Some questions. As far as using solar cells to help recharge the
batteries, what would be a good size to do that with? The other idea, is
thanks to my sister, whom does not like the idea of a steel tube w/o winows,
and likes the open air. How about a retractable deck? I am not
sure how that would work out, but I do think that it would be
interesting. Just some thoughts. As of current, my submarine
design is roughly based on that of the German Type 212A. Using a
diesel/electric propulsion, as well as the ocean current/flow generator to
help recharge batteries while siting on the bottom. Just some
thoughts.

Ian,
Interesting
information. From the looks of the data on there PDF file, they have
larger units planned as well. Also there is a note about it being safe for
indoor use with zero harmful emissions claimed. I'm still not sure if the
cartridges take O2 out of the air, but it doesn't look like you have to
provide any from a tank. I'm not sure what your talking about with regards
to water vapor collection. It sounds like you just pour some water into the
unit of which goes into the cartridge starting a chemical reaction. I
wouldn't expect all that much water vapor to come out of it. But if there
was you could have it's vent going directly into your air circulation system
that has water absorption cartridges inline.
