    The burning the candle to make oxygen reminds of a device I used to use in the Navy for combating fires. It was called a chemox breathing apparatus. You could put it on and still breath in smoke filled compartment and fight a fire.

    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.
