i might have just cylinders. so may just slap some triangles together into 
half of a '12 sided dice' like in roleplaying games. flat surface has 
advantage that easy to place small, strong windows centred on trianglular 
plates. Ryan's trying to put windows onto rounded surface, seems like alotta 
trouble to me. Soon as I help him build his, the skill and parts will lead 
to my 'mark1 superheavy torpedo' sub. going for 10' baby TO START- mark2 
will be 20'-21' long, 25.5"OD later. Carsten, sir, how is 'world's smallest 
sub' measured? weight, displacement, length etc?
Building modular like mk48 torpedo - see tpub.com. Can swap motor 
components, frame so cheap, just leave anchored to frame.
The modules will need endcaps made, just making 'geodesic dome hemispheres 
from metal plate. May have heavy wall front/passenger, light wall/lotsa 
all-the-way-thru-centre support struts, with holes to serve as frame to hold 
battery/motor. Mix 'n match with a bolt-on band around 2 touching 'end caps' 
- really mid caps, cuz everything but control line is isolated.
May use stubby 'cruise missile' wings so bobs to surface if stops, always 
push down.
Any reason wet-cell 'seawater' battery wouldn't work in a lake?
Haven't figured out if want a 'coffin hinge' on cylinder, or have the 
see-thru dome window as entryway. Will dictate what hangs low - horizontal 
(lying) or vertical (standing) in water. Figured I'd just jettison 
engine/battery in pinch, ensure passenger part will go up.
It's a coffin, that makes me kinda nervous...

Figured out the 'pie in sky' mini not micro - using thru-centre of all  
cylindrical hull components, jetski style, may try out vectored thrust so 
fins rigid, just for stability.
