That’s really interesting, Breakable. Antimatter is highly unstable however and would be tough to use as a fuel. But maybe it’s something that could be combined with the DPF Fusion? Antimatter for initial boost followed up with DPF sustained output?
I’m thinking there should be a heading for “Space Propulsion Technologies” within this Fusion Contenders section. It’s an important topic for discussion made more timely by this recent NASA Roadmap: In Space Propulsion on the subject.
