Anti-matter fuel is a dream of sci-fi. Any chance in hell it will ever be able to be produced/found in sufficient quantities to serve as a useful fuel source/energy storage medium/weapon? Personally, I doubt it.
Probably not. You by chance watching the Alien Spacecraft II thing on the History Channel?
The thing about anti-matter as a source of power is that it’s just as unrealistic as talking about hydrogen for cars as a source of motive power. You’re not going to find reserves of anti-matter in the galaxy to mine. You could make anti-matter to store energy. But the creation of usable energy has to come first. And where from?
It may well be the best way to store energy in some far future. But as a source of power it begs more questions than it answers.
