    Looks like that first reaction (Fe +O2) --> Fe2O3 + O (should have an extra oxygen). Looks like the free oxygen should combine with a free oxygen from the NaClO3 to actually make NaCl + 2 O2. Just say'n. The first reaction uses all existing oxygen, so I guess the net benefit is three new airborne oxygen atoms that were previously in the NaClO3.

    Immensely interesting! I am glued to the screen. The questions you ask are so intelligent and help you to get more information while you are talking with the guy explaining things. Second takeaway: these nuclear boats are marvels of engineering, containing so many different technologies to make the boat operational. Thirdly the process of extracting CO2 from the air is just as exciting as generating oxygen.

      The navy also has OBAs (Oxygen Breathing Apparatus). They function the same way with an oxygen candle. Not to be too pedantic, but no oxygen was created in the filming of this video. It WAS however, liberated.

    R134a can also be detected by using the blue flame of propane and waving it around until it comes in contact with R134a (Tetrafluoroethane) or R-12 (dichlorodifluoromethane) when the Blue flame will turn brilliant green. The intensity of the greenness in the flame depends on the saturation level, so one can narrow the search for the source of the leak down by sweeping the area with the flame at floor level. This is not done in submarines for obvious reasons so they use a "Sniffer" instead. But, if you ever need to find a leak of these and some other nonvolatile gasses this is a good way to do so, with due "caution" of course.

    Refrigerant is usually halogenated carbon or halogenated vinyl. These were banned under the chemical weapon manufacture treaty the authority of the EPA was supposed to reach this obligation. It is possible to have refrigerators without refrigerant and without consumption of current. Edison generators and dynamos can produce any voltage and current needed without food or pollutants.

    I have another question. Who knows if you read it. I need help designing and making a structure that is not electronic but mechanical in design. So, the inside layer is simply a compass. The secondary layer (outer sphere) I want it to be able to track fixed points towards our centre solar system. IE like the galactic median. I was thinking that setup process may include pointing at no fixed points from earth, thus it simply tracks the fixes locations of star cluster creating an intersecting points (cross hairs) of our solar system. Then a third layer of fixes galaxies towards our galaxy, painting crosshairs on our galaxy. I thin it would be fun and useful... Of course... the centre of our galaxy is offset from out location, just as earth is offset form the solar system centre for the previous one.... My thoughts is if you like nasa, or navigation. A mechanical globe with layered spherical latices with points could rotate to those locations during night or day, so you always know your position relative to our observable universe.. which is good practice if one is traveling.... Compass direction give us 2D directions on earth... Solar system directions give us 3d dimensional directions on EARTH, but 3d directions in our solar system.. the process continues. their simply looking for stable points between systems of hierarchy that are stable enough to be used as accurate reference to conceptualize where we are in the universe. On earth without magnets it would be hard to create a reference of movement, with the stars changing, one would have to have a very good understanding of timing and location already to use the stars to conceptualize where the planet they are. Setting this up would change depending on fixed objects targeted in the sky... maybe that makes no sense, but it sounds like fun.. knowing your place in the universe... Universal navigator.. the reason I was thinking mechanical system, or limited energy, is that it would work in any place within our Galaxy. without the need of outside source of power except the person, winding it or whatever is used to track, and power its movements.... and with base knowledge one could set it up... to navigate again.. hmm... lost in space.. with a ... galactic compass. lol... rather then a solar or terrestrial one. :D

    The amine absorbs CO2 better when cold, so after the amine gets heated up in the boiler and had its CO2 driven off, first the now lean amine is used to preheat the incoming rich amine in a heat exchanger.This helps to cool the lean amine as well as pre-heat the rich amine, which reduces the amount of external heating and cooling that needs to be done, saving energy. The lean anime is then further cooled before being sprayed again.

    Very interesting video. Would be kinda concerned about potential of flash oxygen fires without the oxygen being highly diluted immediately. Doesn't take much percent higher than nominal to create dangerous conditions in an enclosed space. Presumably, the electrolysis oxygen production is the normal method and maybe it pipes/dilutes into vent system rather than just pouring it into production area...?
