       | TL;DW: normal electrolysis doesn't work because electrolysis with
       | salt water gives you H2 and Cl2 (hydrogen; and chlorine gas,
       | which kills humans). But they desalinate the water and use K-OH
       | (potassium hydroxide) as a catalyst.
       | 
       | The second way is to burn a special candle that is made out of Fe
       | (iron) and NaClO3 (sodium chlorate) , and the heat releases O2
       | from the NaClO3.

       | Man, Destin is cool, but a 30 minute video to answer that
       | question?

         | I agree with your last line, but it's not just Destin. It's all
         | of YouTube. The incentive system is driving creators to create
         | longer videos filled with an insane amount of filler content.

           | It makes long videos much shorter by cutting out all the
           | filler content (~30% of most videos), and has an option to
           | skip just to the highlight of the video.
           | 
           | For this video, it skips you to 6:52, and within 1 minute you
           | have learned that hydrolysis directly doesn't work due to the
           | salt in salt water, it produces chlorine, and you need to do
           | reverse osmosis first then electrolysis.
           | 
           | It isn't AI... it's just other humans who have tagged and
           | marked the videos - and they have done a pretty good job IMO.

       | their CO before answering every question.
