"...and so particle-antiparticle annihilation is a perfectly efficient way of creating energy. If you could figure out a way to do this practically, it would be great: we wouldn't have to worry about global warming, we wouldn't have to worry about Arabs. We would have clean energy and the Arabs would just go back to fighting each other."
--Woowon Kang, professor of physics.
... Except for the fact that creating and storing antimatter requires absurd amounts of energy. Now, if we were to find a natural source of antimatter, well then, that's great. But we probably won't. So much for that idea. And even if we find a 100% efficient method of storing it, creating it and annihilating it is still a zero-sum game. Now, was your professor joking about the whole thing, or just the Arab discrimination?
Colin, read "...if...practically..."
Okay, so it's a conditional statement with an impossible condition. Sorry.
