Here's a video that presents the science behind rotating detonation engines; the article was pretty light on detail. This video is at the other end of the spectrum, clearly intended for other researchers in this domain. Or, if it's over your head (it was for me, at least while trying to wake up), you can still enjoy the pretty damn cool high speed imaging of the detonation waves in this type of engine. https://youtu.be/Ws4kbgfpKCw?t=310 https://youtu.be/Ws4kbgfpKCw?t=310

Deja YouTube, when you click on a link and find you had watched the first 5 minutes of it two years ago.

  No, the link jumps to that point.

  Woah, exactly same here! Video starts 5 minutes in, so I watched and left off there some time. Wonder what the reason is there.

That’s me - that video summarized my dissertation work. I did some follow-on modeling work using neural ODEs that’s pretty neat, too: https://aip.scitation.org/doi/10.1063/5.0063624 https://aip.scitation.org/doi/10.1063/5.0063624

  Wait. So. I do research in the polar regions and am interested in potential novel power sources for extremely remote environments. Is there any future where this kind of engine could be used for power generation? Say by storage in some capacity? Flywheel. Batteries. Etc. It seems to me it should be possible to detonate\fire when you need to top off your storage but that the design need not be limited to propulsion. Am I crazy? This is so far from my field of work, although I was originally a physicist. Energy density, ease of transport, robustness, and all sorts of other considerations dominate in an environment that is very hostile. Aside from nuclear power (which we will never get) the future is pretty bleak for us still when compared to the diverse technology available in more "normalcy climates.
