      PLANTS do both scrubing CO2 and making Oxygen. How many plants would it take to do the same job as these alternatives? How about a comparison video? I'm sure many other fans like me would like to know.

    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.

    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**

    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.

    nuclear reactors do not create electricity, generators do. Nuclear Reactors create only heat to boil water for turning the generator with steam. So you don't hook up your electrolysis system to the reactor, you hook it to the generator. Just to clarify.

    Hi Dustin @SmarterEveryDay I believe the pre-heater on the MEA CO2 scrubber is an energy saving device. When the CO2 is compressed it increases in temperature. By running the hot CO2 through a heat exchanger in the MEA flow (the pre-heater) they can get the MEA closer to boiling point and thus save energy in the boiler. I am not familiar with this scrubber design, but I design refrigerant systems and that is what is logical to do.
