Wade, maybe your buddies can get us some parts wholesale, hehe. I've been 
tracking ballard and Plug stock for some time now. It seems that Plug is 
only going the residential route through GE, whereas ballard has a 
production model for Mercedes (?) automobiles already. I think it's 
Mercedes, I could be wrong. The automobile units look really promising for 
us psubbers. THe residential units typically run off of natural gas or LP 
gas. The auto units run of ethanol, if I'm not mistaken. Both require a 
water source though. As far as the NavCAD, does it model submerged 
structures or just surface units? Like my Nuclear Submarine buddies say 
"there are submarines, and then there are targets". If you can model subs, 
you should be able to come up with some general parameters for the most 
hydrodynamic hull design. I understand that the teardrop is the most 
effecient sub design, from a laminar flow and friction loss standpoint. It 
may not be from a practical standpoint though. Is there a benchmark for the 
model? And usually, they include references or the actual calcs that are 
used in the code. Maybe you can ask for that at work. The reason I say that 
is that sometimes if you have corrupted code, you can tell be fore doing a 
calc, by running the bechmark case. Anyway, just a thought.
Suds
