Submarines

If you think of diesel-electric subs, they are hybrids, running on diesel engines above water most of the time, and on battery-powered electromotors when hiding submerged. The diesel engines can also breathe via a snorkel while the sub is submerged only at snorkel depth.

Nuclear subs can produce an essentially infinite amount of air via electrolysis from seawater and can remain submerged until the crew gets really really hungry and/or angry/horny.

Compressed air is also on board, not only for life support, but also for blowing (emptying) the water-filled ballast tanks that allow surfacing.

Early subs like the Turtle or Hunley had only ambient air on board and of course extra spare underpants for the crew.

Anyone interested in spar torpedoes, the weapon of choice in early submarine warfare? A spar torpedo is basically a bomb on a boom that's attached to the bow of the sub. Ramming the target and leak-proof underwear are mandatory. Being a bubblehead ain't for the faint of heart!

Just for those interested, here is a list of some of the better movies about, or at least prominently featuring, submarines.

Das Boot

The Hunt for Red October

Crimson Tide

Run Silent, Run Deep (Make sure you don't accidentally grab the porn flick with the same title!)

The Enemy Below

The Abyss (For its submersibles and the underwater habitat)

K-19 The Widowmaker (Boring!)

U-571

Operation Petticoat (Always good for many laughs)

Up Periscope

Phantom

On the Beach

The Cruel Sea

Hostile Waters

[censored] (rhymes with "Bell") and High Water

Ice Station Zebra


Voyage to the Bottom of the Sea, anyone?

My children "fired the torpedoes" on this one last thursday

Electrolyzers produce oxygen (and hydrogen, which is dealt with). With a nuclear reactor, no propulsion or ship service air is needed, no engine. If on an emergency diesel, snorkeling is necessary.
 
They can also burn what is called an oxygen candle. It produces oxygen without any machinery.
They also have to get the C02 out of the air. The chemical Amine is used in this process.
Compressed air and Oxygen are two very separate things on a Submarine. Extra oxygen is pumped into oxygen banks. Compressed air has it's own set of air banks.
Atmospheres are monitored, as you can imagine you have to get the right amount of oxygen content in the air. Too little you are sleepy all the time. Too much? You don't sleep and you have a headache.

I was going to mention it if nobody else did.
Not the best movie ever made, but it has its moments.

(They really need to do a remake of this!)
 
Many of my friends were navy nukes. Both fast attacks and boomers during the 60's. And 70's. I learned quite a bit. Were it not for Rickover we might have had wwIII.
 
"Das Boot" - an excellent film. I like to watch it in German.

My favorite character is the "Chief" who repairs the sub when it is on the bottom with very little hope of surfacing again.

When I was in High School, I seriously wanted to join the Navy and become a "Bubble Head."

I remember telling my Uncle Buford about my dreams to sail under the sea. He responded in his thick Georgia accent, "Son, don't you know people have perished to death for lack of air on those things?"

God had other plans for me and I never joined the Navy.

I think Jules Verne had a movie also. I loved it.

What type of sub were you on?

Are you serious?

THere's a GREAT scene in K19 when the chief engineer hands the poor S0B sailor who offered to go into the reactor compartmment a pair of cloth coveralls and says "Here is 'radiation suit'". The both have a "In Soviet Union it IS what it IS" look.
