<div>Interesting, because for my part I'm heading in the exact opposite
direction. My next sub aims to be the ultimate in simplicity, and will
make Snoopy look really complex by comparison. As for the heat, I don't
want the complexity of A/C and would be content if I could simply open
the hatch, hence freeboard is a priority. I could augment that by simply
adding a blower for ventilation on the surface. The thrusters will be
fixed, no linkages and actuators like Snoopy. No VBT. Thrusters and
speed controllers will be four identical units, and will be replaceable
in a few minutes (thrusters are emergency-droppable, so to replace you
just drop them). The goal is to have a sub so simple that I can ship it
to a remote location and know it will have no technical glitches
whatsoever and that I will have spares on hand at all times for it's few
moving parts. </div><div><br></div><div>It will have 12 batteries
in the main banks, and when you add to that the rate at which battery
density is improving, I think there'll be enough juice to render a
diesel unnecessary.</div><div><br></div><div>I once went as far as
buying a tiny diesel to evaluate it for use in a sub, but after tests I

><div>Some quick questions / observations / musing come to
mind as I sit here editing <var
id="yiv1393084931yui-ie-cursor"></var>videos.</div>
<div> </div>
<div>It looks to me like Alvin's thrusters all have a 90 deg drive
arrangement like yacht bow thrusters. Some of these off the <span
id="yiv1393084931misspell-0">shelf</span> units are hydraulic, but way
over powered for a Delta / Gamma sized sub. <span
id="yiv1393084931misspell-1"><span>There</span></span> are however, lots
of little hydraulic motors out there, a slew of them. Ive also seen
drive components, reductions, etc, that simply were not available to
George. How much trouble would it be to go hydraulic all around? </div>
<div> </div>
<div>If DC motors must be used, in my view then the single
must have improvement to the T-Rex design is the addition of a mag
coupling.</div>
<div> </div>
<div><span id="yiv1393084931misspell-2">Alecs</span> <span
id="yiv1393084931misspell-3"><span>experience</span></span> has me
rethinking self sufficiency. It would be nice to charge the batteries
and the HP tanks independent of a surface boat, eliminating the need to
raft alongside in swells. All this <span
id="yiv1393084931misspell-4"><span>convenience</span></span> means a
"Tours 66" type of arrangement. But Tours 66 weighed in at 10
tons.</div>
<div> </div>
<div>Everything is now downsized like that little AC unit I posted,..
take a look at this marine gen-set (note dimensions) <a

<div><span id="yiv1393084931misspell-5">Hmm</span>, could this not be
enclosed in the hull during a build, or otherwise slung longways down
the hatch into a 42" hull? No prop shaft and seals, (you still get
towed) but <span

id="yiv1393084931misspell-7"><span>charge</span></span> capability for
both batteries and HP air with an equally downsized compressor!?!
</div>
<div> </div>
<div>So the question of the day is,...</div>
<div> </div>
<div>Is a comfy air conditioned & self sufficient research capable
PSUB for sport diving in Florida / <span

realistic goal at around 3.5 tons and $8-$10 lb?</div>
