Isn't the important thing from a practical perspective (agreed that the new science aspect is more interesting) that if proved this has near infinite specific impulse? (As bizarre as that sounds) From an interstellar transport standpoint, that would seem a game changer. At minimum, slipping the bounds of the rocket equation and being able to accelerate an endlessly looping hulk to closer-to-c velocities seems fascinating. I'm curious what the specific impulse numbers look like given the hypothetical conversion rate on this powered by pure fusion.
