Antimatter annihilation releases more energy per kilogram than any other known process, so it is tempting to picture it as a future fuel. This simulator builds the whole production-to-power chain instead: a particle accelerator manufactures antiprotons at a rate you set, a 3D magnetic (Penning-style) trap stores them — visibly leaking particles into its walls when the containment field is too weak — and a "trigger controlled release" button dumps the survivors into a collector to recover their annihilation energy on demand. A live energy ledger tracks what was spent making the antimatter against what storage losses wasted and what the release actually recovered, converging every run on the same real-world conclusion: producing antimatter costs on the order of a billion times more energy than annihilating it gives back, so it functions as an extraordinarily energy-dense storage and delivery medium, not as a net energy source.
