Since the air we breath is ~79.2% nitrogen and 20.8% oxygen, in a sub does the Nitrogen levels remain the same? and if it doesn't, how is it made up to keep the same ratio?

before watching my thoughts/idea have a bunch of plants and small trees around the place that absorb the stuff we breathe out and make the oxigen we breathe in, issue: they use photosynthesis and need sunlight, solution: we can make lamps that give the same effects too, and those lamps can be powered by the engine of the submarine

Why is the need of scrubbing the CO2? Shouldn't be enough to add the oxygen? (I don't understand why is more CO2 released in the air)
Eddie J. G.
Eddie J. G. Il y a 3 heures
We exhale CO2... as in, our bodies produce CO2 as a byproduct of metabolism. We’re constantly making CO2.

@J Steensgaard yes... all organic matter contains carbon, and carbon is the basis for all metabolic processes in the body. We get more by eating it.

@Eddie J. G. But wouldn't that mean that the people are eventually 'emptied' of carbon? The people need to get the carbon into them somehow. Is that all through food?

When he said it was "self oxidizing", I realized it was a form of thermite reaction, where O2 was an output of the reaction, released into the atmosphere. Amazing.

i dont understand to it... so they are making oxy-hydrogen gas and separating hydrogen and breathable oxygen? because otherwise they could die due to poisoning from "browns gas" and i thought that this process of electrolysis is able to use only in welding technique or cars and not even thinked about it can be used as oxygen generator to submarines. nice video
Eddie J. G.
Eddie J. G. Il y a 3 heures
We purify water, then we use electrolysis to separate the oxygen from the hydrogen. We discharge the hydrogen overboard and store the oxygen or release the oxygen straight into the air.

The lithium hydroxide combines with the CO2 to become lithium carbonate and... just stays that way. We’d just throw it away.

Fun Fact: We are capable of scrubbing the CO2 out of this planet's atmosphere similarly to the way described in this video in amounts equal to or greater than what we produce. We have already built and used facilities to do such, with the largest currently being built in Texas. It is a 1 Megaton atmospheric CO2 plant, which is the equivalent of 14,000,000 trees in that one CO2 plant. It works great and we would only need 40,000 of those facilities across the world to capture all of the CO2 produced on Earth. Sadly all our anti-CO2 funding is going into monetarily inefficient "green ideas" hyped by the mainstream environmentalists funded by certain institutions focused on selfish goals which are not going to help the majority of our people prosper while keeping our environment healthy.

The Clinkers are named after an old blacksmithing term. When a blacksmith burns coal, some of the coal's impurities cant burn and are left behind, so you end up with a chunk of hard rock like materials in your forge. But when those chunks fall in your forge blowing fan they will "clink" around until settling or falling out.

I could be wrong but I believe NaOH can work for scrubbing CO2. I always thought lithium hydroxide was used because it’s the lightest available hydroxide available. And on a boat or in space I hear weight is a bit of an issue...

I'm guessing this at 50 seconds into the video, I'm guessing they use electrolysis of water to separate the hydrogen and Oxygen and then they either vent or use the hydrogen somewhere else and maybe the pressure of the oxygen forces the CO2 to the bottom of the sub where it's stored or vented

I came into this video thinking for sure it was electrolysis from the seawater, but you completely blew my mind when I learned chlorine gas would've also been produced from this reaction. Now I'm *very* interested to hear how they do it. Perhaps by somehow removing the carbon from the CO² to produce O²? Guess I'll find out... **Presses play again**

Electrolysis would be my guess. Tons of surrounding water, tons of electricity because you have a reactor, and you're already using some for desalinization.

Destin... Huge fan.. love what you do, but I was concerned that you suggested sprinkling LiOH on the bunks. I'm not sure what form this LiOH is in, but it looks like pure LiOH is pretty toxic (3 out of 4 on the Health Hazard scale) along the lines of NaOH (Lye). Might be interesting to see what we could learn about how this danger is contained. Maybe "the professor" (Martyn Poliakoff) at Periodic Videos might have something to say.

I've got a really cool idea for a video. I'll try to make it as short a possible. The idea is basically catching a snowflake turn from solid to liquid then to gas all in one slow motion shot. I believe you could do this by lowering the atmospheric pressure and increasing the heat inside vs outside. I believe I witnessed this and would love to recreate it and see it in detail.
