I always liked the idea of canning goods, first it was just wonderful to be able to stack food, but now that food is already stackable canning has really lost is need.
I figured canning would be a great use for high density storage for food stuffs, by combining 6 to make a canned food pack like the battery pack. this way you can store 6 * 64 = 384 food items per storage slot.
