Hi Pat - Back from holiday - get 210 emails..in one week about some kind
of
90 knots aluminium powered half-biology-submarines..
Sgt.Peppers has change its place and is now in a museum in Bremen
called "Überseemuseum" (Oversea-museum) for 6 months. Its part of a
special exhibition
called "Pirats and treasures" contains also a small part with salvage
equipment.
Main display of the exhibition is the "treasure" of the pirat ship Widar
or Wydar
(I don't know the spelling - I haven't time to visit the museum.)
Sgt.Peppers needs a stronger dome, a refit of the Live Support system
and some
new pipe work on the hard regulator tank. But it is in ready-to-dive
condition today- all it need
is to recharge the batteries. Maybe I will sale it - or refit it after
finish my work on CSSX - or build a small torpedo-like-tube section in
CSSX to use Sgt.Peppers
to look for the door..
CSSX update : Finish work on deck of section 1 and start with the sail.
Bought some steel plates
and pipes for the section 2 : fins, rudder, shaft etc. Have steel
material here to work
on the sub for the next about 6 weeks without a break. Will see..
Motors/Sgt.Peppers : Scuba gear with small pressure air bottle and some
simple rubber pipes to all engines and batteries.
Very usefull if you have more than one engine or the batteries outside
without a own pressurehull.
Found it better than oil compensated engines/batteries (was before). And
if the pressure gauge indicator on the scuba valve goes down during the
30 minutes pre-dive checklist time - something is wrong - maybe you
forgot to close a vale or a seal or o-ring is broken - simple. But oil
is also a good indicator - if you
dive and there is some bigger amount of oil on the surface - you friends
know something wents wrong.
technology = with a minimum of time, material and equipment get a
maximum output.
A Live-support system which needs sunlight to work in a spacecraft seems
okay - but in a deep dive submarine ?
Gill's like a fish would be maybe better - some kinds of
special-membrans outside the pressure hull.
