Wouldn't 'Let's go get smarter together' or 'today' or something of the likes be a bit more appropriate, due to it being an instance of becoming smarter rather than a culmination of instances at once? I feel like 'let's go get smarter every day' for one specific instance of becoming smarter is a bit misplaced and misnomed in comparison, and leads to a moment of awkwardness in my mind; as if it's advice, rather than a welcoming invitation. Maybe it's a solo perception, but here's to hoping this mention of insight can provide some benefit. Cheers, Destin.

I think the "preheating function" is just a heat exchanger with the output of the boiler stripper. Take the energy out of the lean MEA to better condense it and put in the rich MEA that you're about to boil. Save some time, save some energy loss.

I got a good chuckle when he said the oxygen generator was "down." I spent 3 years on a boat and not once did we ever operate that piece of equipment. It's nickname was "the bomb" due to the fact that it generates hydrogen gas and can be extremely dangerous. When we went on mission and would stay underwater most of the time, we'd just load up on oxygen candles and burn them as necessary. It was not uncommon for oxygen to drop to around 17%, which makes you constantly tired no matter how much sleep you've gotten. The other thing is that clean, potable water is at a premium on a submarine. Our distiller could provide 10k gallons per day (if the operator knows what they're doing, if they weren't very proficient then significantly less). That's for the entire boat: drinking, washing dishes, laundry, showers, etc. We'd have to constantly remind people to limit their water use so that we didn't run out. It would make little sense to waste water on making oxygen when you can just burn a candle. Oh, and amine? It gets everywhere. Go up to any AC vent in the engineroom and you'll notice a slight drip of an oily substance. That's amine. It will funk your clothes up for weeks after, even with repeated washing.

The MEA being processed is similar to a LiBr absorption chiller that uses steam or hot water to boil the H2O (which is the refrigerant) out of the bromide solution and repeats the cycle. This chiller also runs in a vacuum.

He said two at a time maximizes O2 output.. obviously that's true per minute, but did he mean overall output? Does the Oxygen in the candle bond with another molecule creating a waste bi-produce or the like which is reduced when another nearby candle is also consuming the incidental molecule?

When I was a young kid, I took my Snapciruits kit and put each end into a cup of saltwater in an attempt to produce hydrogen. Thankfully, I didn't poison myself, but one of the ends of the extenders turned bright green, like the Statue of Liberty, and the other turned bright orange, like unoxidized copper.
Critical Insights
Critical Insights Pirms Stundas
I suspect the paper like covers over the ends of the candles were to reduce the chance the candles ignite due to jostling during transit / storage. Great video.. I'm always thinking about how I can engineer 0 emission's sustainable environments, and it's always useful to watch how the old hands go about things :-)

"Clinkers" are depositis of creosote that build up in wood/coal stoves/furnaces. They caused issues an they looked like those spent oxygen candles I am guessing old school sub guys nicknamed them clinkers after they're burnt cause they look like "clinkers"

"so this is in the middle of the boat?" Sure, if you're a coner. Too bad they couldn't see the oxygen bleed back in shaft alley, or the CO burners. Another way to regulate the atmosphere is the obvious way. Ventilate at snorkel depth

Hey Destin, could you do a video on classification and specifically what gets a certain topic classified? It occurs to me that all this technology is publicly funded, and the government owes some explanation of the technology to the public, but there's a fine line at which that public disclosure becomes "giving information to the enemy". A lot of conspiracy theories online seem to involve "evil government secrets" and that seems like something a person like you would be able to debunk, given your experience with classified information.

One day you will get smart enough to see that NASA is a 52 millions per day scam. Black budget, etc. Did you happen to think about the small spaces into a submarine in comparison with the ISS BS? Even though a submarine is closer to land and help, etc. Oh and not moving at BS 27000 km/h on a thing that can't avoid an object on its way if there would be a way to detect it on time at those speeds. Keep promoting the NASA scam, every day more and more people are waking up. Star wars freaks in 1,2...

Coal is basically oil infused rock. After burning off the oil, the leftover rock in a coal fireplace is called 'clinkers'. I'm guessing that the unburned residue in those 'candles' gets it's nickname from the coal equivalent.

My first guess as to how to create breathable air would be by way of water split by fuel cells. Hydrogen gas can be used to power the engines and Oxygen can be added to the atmosphere. Carbon dioxide can be collected by dehumidifiers.

One of my payloads for ISS is working on a system to scrub CO2 with out consumables (cansters) or the MEA/moving liquids. MEA process can not be used in 0G as the differences in density in the expelled co2 gas and the mea do not allow the co2 to rise out of the suspension. In 0g Buoyancy processing can not be utilized as a key part in separating gasses from liquids.

Preheating of the MEA is mostly likely a heat recycle, where the hot lean MEA is used to heat the rich MEA in some heat exchanger. This also effiecently cools the lean MEA, which increase its ability to absorb CO2 since cooler liquids have greater gas solubility.

I did electrolysis for a science fair project (testing the effects salt had on speed) and decided to take a sniff of the "oxygen" side, during a run with saltwater. Didn't even clue into the fact that since the house smelled like a pool something might be up. 😬 Glad I had the sense to step outside immediately into the fresh air as my airways drastically restricted! Needless to say, I stopped experimenting for the day!

As a retired U.S. Navy anti-submarine and multi-sensor specialist, I can assure you that all our nuclear subs CAN break through the ice to "get fresh air". Mainly they must have this capability to launch ballistic and guided missiles. They also have the ability to release "sensors/transmitters/receivers" that can break through the ice when necessary. The technology on our newest boats is mind blowing indeed. Just wait until you see the 6th gen fighters and bombers!

O2 partial pressure of 153 torr is normal where I am, but obviously the ambient pressure on the sub is higher so you'd be aiming for what? 160 torr? 200 torr would be a fire hazard.
