Bill,

There's a problem with having all the answers, old bud. You'll miss one of the questions. That Gaelic shrug and the "I got to die sometime" thing will get you killed, given the opportunity. Risks are to be managed, not taken.

The Hydrocaps are great. But they get poisoned when splashed from underneath with acid and lose efficiency. And the only way to tell if they are working is to put your hand on them while charging. They warm up. A cold one isn't making it. And you can't do that in the battery pod.

Towing the sub will rock the pod, generate some splash, and potentially posion the caps. Unless the folks in Miami have redesigned it, that is. They also have caps that are bracket mounted. These return water to the pod, rather than the battery, so don't rejuvenate the acid. Also, you use oxygen from the surrounding atmosphere in combination with hydrogen to make the water, so the pods will be under a slight, but noticeable vacuum after heavy use. You have to vent.

DC motors make sparks for a living, so you might want to think about putting a baby blow torch in there with your hydrogen generation unit. Potting each wire might not be necessary if you just packed RTV or something into some part of your tubing around them. Then supply air from the same source as your pod equalization, but use dedicated tubing.
