Frank, Another reason to have a surfaces
hip for transit; If not a perfect calm lake, the passenger in the hull of the
sub will be seasick in 5 mins. For the captain is
everything fine as he can see the horizon;-) Emile Van:

[mailto:owner-personal_submersibles@psubs.org] Namens ShellyDalg@aol.com Thanks Jens and all. I expected to get
some feedback about a gasoline generator inside the sub. I was just thinking
how a guy could run on the surface without draining the limited battery power. I'm hoping to have a small outboard
on my boat for long distance surface travel and although it is planned to be
small enough to bring inside, it won't be. ( A 20 horse Yamaha or Mercury will
just fit ) The plan is to transfer it to the surface support boat when
diving. Getting back to the power thing though, my
early designs included a tether with power, communications, and compressed air
lines when diving above 100 feet. This could have given me 220 volt
AC power to drive the sub, with battery power and no tether for deeper
dives. As my knowledge increased and good advice received from the group
it became clear the additional resources available from a tether system
probably weren't worth the extra complexity of a dual power system. ( 220
volt AC and 36 volt DC ) As for surface travel, a small outboard
just seems like the most simple for a submarine so small. I was just crunching the
numbers in the shop last night and figured it COULD be possible to run a
little generator while driving the sub out say 5 miles or so to reach the
dive spot. Those little camping generators run a
long time on a gallon of gas and are pretty quiet. Still, 1/2 speed on two
Minnkotas won't get you very far in a couple of hours. That's why the big guys
have SHIPS to carry their subs around. Must be nice to have a big check book. Frank D. Geen virus gevonden in het binnenkomende-bericht. |
