How A Nuclear Submarine Crew Breathes For 6 Months Without Surfacing
How do 140 people breathe for 6 months inside a sealed submarine… without fresh air?
Modern submarines don’t store oxygen—they create it from seawater using powerful systems that split molecules, remove CO2, and rebuild breathable air every second. This same life-support technology powers the International Space Station and could one day keep humans alive on Mars.
Discover the hidden engineering that turns a submarine into a self-sustaining life-support system deep beneath the ocean.
1. Water current splits hydrogen from oxygen.
2. Depending on actual quantity, you might not want to vent the oxygen directly into the passenger quarters.
3. Hydrogen, of course, gets rerouted to an/the empty fuel tank.
4. Electrolytic oxygen generator.
5. Carbon dioxide scrubber.
6. Monoethanolamine.
7. Heated to release the carbon dioxide.
8. Possibly, through either fusion reactor, or all that vented up heat?
9. Resting adult consumes five hundred fifty litres of oxygen daily.
A. Hospital operating rooms.
B. Rebreathers, miniaturized carbon dioxide scrubber.
C. Carbon capture.
