Magnetically confined rotating detonation engine
  [vote for,

Reading about rotating detonation engines it occurred to me that there must be enormous friction losses in the chamber. So the idea is to use magnetic, rather than physical, containment. An additional benefit would be the ability to easily shrink or expand the volume, and change the shape of the chamber for best efficiency in various flight profiles and external/internal pressure combinations. For example letting the engine compensate for reduced LOX pressure when you're near to running out instead of using a heavy and power-sapping pump, or going from atmospheric to space flight.

The idea title reminded me of this. Otherwise there is no relationship to the idea whatsoever. [DrBob, Aug 31 2021]

       ^ Feels like an exam question? [Voice],You a have two months. Answers must be typed. A Wolfram script will gain extra credit.   

       But, we don't even have the light, hot superconductors yet.

       Is it?

       Can a molecule can have it's electron shells forced into set of electron motion patterns around the atoms?   

       Stepping out from the factual ledge, it would probably need some sort control of the atoms motion, concurrent with magnetic field manipulation(s).   

       Pre-patterned fuels, ready for higher energy level combustion?. Sorry just imagining wildly stretching green goo, from hard ball centres, combining and snapping.
