    • 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.

  • Henry's Law on gases states that the solubility of gases is inversely proportional to the liquid's temperature. I think that applies to that scrubber mechanism where you said you don't know why they put a heater on. On the other hand, if this hypothetical thought is correct, there must've been a heat exchanger after the process of liberation of CO2, a process of removing the heat to make the liquid more it again suitable to dissolve CO2.

  • Looks like 10-15yr old tech running the sub. I am amazed to see so much of our military equipment with old equipment. The B-52 recently had its end of service date changed. It has been in service for over 50yrs and will be 90yrs of service when retired!! Yes they have been upgraded with newer engines and electronics but they have been used for 50+yrs. Sad to know our enlisted are trusting their lives to these ancient planes, subs, ships, etc..

  • I'm gonna guess electrolysis of water to h2 and o2. Edit: dynamite on that hit. Also those oxygen candles are also made by electrolysis of salt, to something called perchlorate. Edit again: never mind, it's chlorate. Same thing more or less. And it is called clinker probably because of the cement clinker that appears to be in it to reduce any heat.

  • Growing I loved watching educational shows that teach you things... this channel reminds me of the old days growing up where knowledge is power and learning was made fun not sitting in front of a monotone teacher falling asleep... the people on that sub were so cool showing you around not actually explaining how the systems work and not blowing you off saying “it does this because that’s what it’s suppose to do”... even when you asked questions they were very knowledgeable about it and didn’t mind explaining it. Great job to everyone including you Destin... keep up the great work because knowledge truly is power.
