       | This article - https://www.hydrogen-peroxide.us/uses-monoprop-
       | steam-generat... - explains the basics of hydrogen peroxide
       | propulsion technology. For example, having 50% peroxide, one can
       | make more concentrated one - like, 85% used by Britain in their
       | orbital launcher Black Arrow - by relatively simple evaporation.
       | I guess the problem is that it's less useful for video.
       | 
       | It was really good to see catalyst pack experiments with printed
       | porous ceramics. It would be very interesting :) to see if that
       | ceramics - and active ingredient potassium permanganate - would
       | stand higher temperatures of decomposition of higher
       | concentration peroxide. But that's an exercise for the viewer -
       | and the technology for that, a specialized 3D printer and high-
       | content ceramics photopolymer aren't too accessible for many.
       | 
       | The video - and the channel as a whole - are still pretty good
       | though.

         | That's not entirely accurate, and even then it's not really a
         | bad thing if it were.
         | 
         | Integza has a number of videos improving on former videos'
         | designs, and in the case he isn't satisfied with a design he
         | always talks about how he might make it better, usually near
         | the end of the video.
         | 
         | He'll often make followup videos with the next iteration.
         | 
         | Not everyone needs to be the next Elon; let him have his fun.
         | His videos are entertaining, and that's great.
