      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.

    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.

    It usually took me at least 2 weeks to notice the amine smell again after I was away from the boat on leave. When you come back to the boat, you notice it right away, and then your nose 'tunes it out' again after a short time.

    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.

    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.
