I'm curious why the pulse-jet keeps cropping up in discussions of possible or
alleged advanced high-speed aircraft. Isn't the thing inefficient as heck?

Pulsejets and Pulse Detonation Engines are completely different devices,
despite the similarity in name and the vague similarity in operating
principle.

(One important difference is that pulsejets went from concept to flying
hardware very quickly, while PDEs have been The Engine Of The Future for
nearly half a century now.)
