OK, I take it back, it seem pretty safe to name the greatest potential energy source, so long as it’s antimatter. |
But unlike Antimatter, after a certain point in time, a large enough self sustaining fusion reactor doesn't require any fuel, and it's energy production will eventually achieve greater energy than Antimatter Annihilation, and it will continue to achieve even greater amounts of energy after that.

I suppose we all thought that, in one way or another"
