All very interestig and informative. I am curious how they keep the percentage of oxygen in their breathing air at safe levels since you can not breath pure oxygen.

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)

All you need is a bit of greenery - plants produce oxygen and consume CO2 although....a bit hard without sunlight.

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

so... the mea doesn't scrub the carbon off of the co2... it actually takes the co2 out of the air

Silvia Fox

Silvia Fox . 17 hours ago

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.

Is this... like... "legal?" I mean, isn't showing all this stuff kind of like revealing somewhat sensitive information, possibly harmful in the wrong hands? I mean.. shows where and how all the mechanisms for one of the most vital functions keeping our nation's service people *alive*... seems kind of sensitive,

About 40 years ago when I was a teen I bought an Oxygen Welding device from Sears which used a small version of those candles with a red substance on the tip, you'd light them just like you would a match and they burned at a phenomenal rate of heat.
