Thanks Vance.
I realized now you didn't mean anything. I'm too
darned sensitive sometimes. Gotta work on that.
I could probably rig up a system wherein i could
have insulated wires coming up thru the wetsub hull from the battery pod and
that were sealed on their wire ends until I uncapped them and
passed them over to the dock to hook to the
recharger. Also I could have several air lines that passed up thru the wetsub
hull coming from the battery pod that were also sealed on their ends until
I
uncapped them and hooked them to a blower to
circulate air thru my battery pod while it was recharging. But this would entail
two more penetrations thru the battery pod for the forced air system and
another
penetration for the wires going to the batteries. I
can see how this would be handy if I was going to be out a long time and wanted
to recharge from another boat. But since I am limited to how much I can use
the
wetsub in one day to the same limits of scuba
diving and need to offgas nitrogen from my body whether I am simply diving or
using the sub while diving, it is probably something I won't install right away.
I won't really need
to recharge on the water that day because
(according the the depth I have been diving at of course) I am limited to just
so many dives in a day because of nitrogen buildup in my blood. I'm thinking
that 4 batteries would probably
be more than enough for my purposes for a days
diving, considering that my 24 volt minnkota would run full speed on just two or
half speed on just one.
Most of the diving I will be doing will be just day
excursions, launching the sub via trailer from the boat ramp.
But you are right, it would be a handy thing for
those "just in case" instances if I wanted to go out somewhere and anchor, stay
overnight on the boat, and then dive with the sub again the next
day
and use the generator on the attending boat to
recharge the batteries on my wetsub with.
So it certainly might be something I would
consider doing later on.
Now about that vacuum in the
battery pod.
Since I will have the air equalization system
installed on my battery pod using the scuba regulator which will constantly
compensate for outside water pressure and vent air into the pod accordingly to
compensate
for that outside water pressure, how can I get
a vacuum in my pod? If a vacuum tried to form in my battery pod, that
would cause my scuba regulator to sense a decrease in pressure in the pod, and
the scuba regulator would
then vent air into the pod until the pressure
inside the pod was equal to the pressure on my scuba regulator. It would do this
whether the scuba regulator was underwater of not, correct?
Now let's say I am on the surface or
on the trailer and I recharge and have my air tank going to the scuba regulator
closed. So now my pressure equalization
system is offline so it would not compensate for
any vacuum that might form. But still, how does a vacuum form at all?
If the oxygen that is seperated from the hydrogen
recombines with the hydrogen via the hydrocaps or hydrolator to form water, how
does
a vacuum form? Is there somehow some loss
of gas that I am not taking into account? If so, how? What has
happened to that gas volume? Where did it go?
Kindest Regards,
Bill Akins.
