Others are pointing out that this is (very) hot fusion. But I'd just say that if you know the first thing about fusion, the title is actually very simple, ie, stellarators and tokamaks are competing designs for magnetic confinement fusion. Of course, no one is born knowing anything about nuclear physics, and it's not really a casual subject of conversation, so there might be a lesson here that people could take about writing in domain specific jargon and how inaccessible it is for outsiders.
And if you know nothing about fusion, the title seems to be crafted of made up words.
But if you take one glance at the comments, it becomes clear. So I guess the title was sufficient to pique my interest, which, after all, is the purpose of a title.
