| Thanks for the welcome back Brent. I spose that is true, more power cannot be a bad thing. I did some research on a few companies that have products that have been developed for bus and auto transport (VERY SMALL systems btw) not more then 3 cubic feet or so. And they produce 100Kw and up to 450 Amps... The systems are most definitely there for us to install into psubs. The next challenges in my book (because I do want to use Fuel Cells to power my vessel because unfortunately I cant use a Nuclear Reactor just yet :-( )
1 - Fuel storage system 2 - Where do you buy Commercial grade hydrogen? 3 - figuring out how to hook up their system to our on board systems (they have both AC and DC systems) 4 - I cant remember, its to late, and I just got out of the hospital for the third night in a row, I cant seem to kick this bacteria infection I have (oh btw.. happy new year. haha). But hopefully as soon as I am well (within a week or so) I will be diving deep into designing my sub down to every single nitty gritty detail. Btw.. Peter your still my psub idol with your Kraka and UC3 lol.

There is more interesting projects in the works in this group then every before. I would expect it to be hard to get an average power draw for a PSUB unless you narrow it down to a number if different class sizes of PSUBS and even then it's all over the place. I would expect that if there was allot of fully submerged, electric power available to almost any PSUB, the owners would either install larger and/or more electric thrusters, and/or just plan to get more endurance out of there craft.

On the subject of Hydrogen Fuel Cell Systems.. how much power does a
TYPICAL PSUB draw? I have done some research on systems and they can
produce massive amounts of KW, but it is the Amps I am worried about.
The systems I have been investigating are also designed for
transportation systems, both automotive and transit bus, which does
not eliminate it from the larger psubs.
Also on a side note, sorry I have not been around in such a while, but
after going through all of the emails lately, I have been recharged
and am ready to get to work (or at least planning that is. :-) )
