      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.

    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.

    Why don't subs run out of air? It's called breathing through your nose.

  • mugenrios2k

    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.

    When I read the title, I thought they were using electrolysis to get oxygen and just pump out the co2

    Before anyone says "We should just use CO2 scrubbers to reverse climate change" - CO2 scrubbers takes a LOT of electricity to run. Also, you are just capturing the CO2, not getting rid of it.

    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!

  • Nico Plowman

    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!

  • gojewla

    I am surprised that electrolysis is fast enough to be practical for something like this.

    One can also use Calcium hydroxide a.k.a. slaked lime to absorb CO2. The products of the reaction are Calcium carbonate and a pure water.

    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.

    With the new Mars rover having the MOXIE to create oxygen from CO2 - if we have the means / science to convert CO2 to Oxygen and have power from Nuclear Reactor of Sub why would they not use a MOXIE to take CO2 and remake Oxygen without having to use these candles.
