    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.

    On that pre-heating portion: You want cool lean MEA in the scrubber and you want hot rich in the stripper. So you could either put a refrigerator or radiator behind the stripper and waste all the heat you put into the MEA or you can use a heat exchanger. With a heat exchanger you transfer the hear from the rich MEA you want to cool down into the lean MEA you want to heat up. This reduces the need to put additional energy into the system for heating and cooling.

    Awesome video as always! The preheating stage at 23:37 with the MEA solution must be to increase the overall efficiency of the final heating stage, in a sub every space must the carefully design to ensure minimum space is occupied, taking advantage of the higher contact area of the pipes and preheating the solution during pumping to the final stage is cleaver and rises the overall efficiency of the process.

    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.

    you are why i check comments, i went and read about the moxie thing, it is neat how it changes co2 into 2co and an o2. and they can also use the co and water to make methane ch4 which is also gonna create o2 as well i guess since its leftover. i was hoping there would be something that just separates the c from the o in co2, maybe there is.
