    • 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.

  • It's called a clinker because The word was passed on from UK submariners - original clinker bricks are bricks of clay made kinda shiny brittle and/or vitrified during a firing that exposes the brick to very excessive heat. Real/actual building clinkers are/were commonly used in the UK for building homes, to add historic looking appeal. People still use them to build homes that they want that certain aesthetic - it (more) often does from people using reclaimed clinkers now, as they aren't made very often anymore..... Phew, that's probably a bit too much info. But there you go, in short: a clinker is just a brick exposed to very very high heat.

  • So why don't they use a couple plants and shine some light on them? They tried it in a russian closed atmospherics experiment and the problem was the plants grew and quickly produced too much O2, causing a fire hazard, so they had to start burning plants to remove some of the excess O2. But with some good controls and experienced operators it should be perfectly feasible.

  • 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.

  • 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.

  • "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"

  • 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.
