How to Make Anti Matter Into Energy

If we could somehow take pure matter and transform it into pure energy, there would be a huge amount of energy eaten. A single raisin has more energy stored in it than a nuclear bomb. We haven't been great at figuring out how to tap into that energyrit because i guess the energy inside of a raisin likes to stay there. It costs more energy to make anti matter than you get out of the anti matter afterwards. So it's not efficient for commercial industries, for example. I love anti matter. It's wonderful. I wish we had so much more of it so we could study it and do all sorts of things with it.
