[PSUBS-MAILIST] Ictineu 3 launch

[Joe Perkel]

I notice some similarities as well as significant differences between that battery module and the Deep Sea units we've seen and discussed before. Aside from the lithium technology of course.

Of note are the oil filled case, the case itself, and the transparent flexible membrane covering the whole works. The difference that catches my eye is that the electrical penetrations are through the case as opposed to through the membrane like those other units. That's significant because to my eye going through the case looks to me to be easier and more trouble free leak wise for the homebuilder.

So my "idea man" brain has a question for the shop wizards. 

Can a low cost relatively lightweight trouble free power module be reasonably built using?,....

1) Low cost lead acid batteries with hydro-caps
2) FRP case with appropriate penetrations through the case
3) Oil filled case with membrane as opposed to reservoir compensation

My thoughts are two independent battery boxes in tandem along the centerline, possibly jettison-able.

The brother and sister team has finally water dipped the sub and done preliminary submergence and thruster testing. The announcements came out today on social media (FB, etc). It's worth looking them up if you haven't done so already. I talked to them for awhile at UI last year, and this thing is seriously impressive. 1200 meter depth capability with a big window, no less, and it only weighs 5 tons. That's pretty good going for a crew of three. Plus some really good looking lithium polymer technology. 10 kw/148 volts from a single box that isn't all that big or heavy (which they are advertising as for sale separately). Overall, it's a real beauty. The builder/designer is a fiberglass guy, and the fairings and whatnot are sheer art. Very nice.
