The Antimatter Engine is a very simple engine that produces power proportionate to how many “cores” it has once it is turned on with fuel inserted. Cores are reactor segments that are bordered by two reactor segments.
The control unit, engine parts, and fuel jars can each be ordered from Cargo.
To create more power after the fuel has run out, eject the fuel jar, place a new fuel jar inside, and set the mode to Injecting once more.
Additional AMR Parts can be ordered from Cargo for $30. This crate will contain an additional 12 segments.
Fuel Jars cost $15 for 3 jars.
Adding segments to the Antimatter Engine will increase the number of cores, in turn allowing you to safely increase injection rate. Remember that this will also cause the engine to deplete fuel faster.
The power produced by an antimatter engine as it is expanded has linear growth, and is given by the formula: (Injection Rate)^2 * 20000 / (Number of Cores). If you are injecting at the maximum rate, this can be simplified to Injection Rate * 40000. Eight cores should be enough to power a station fully at full injection. This will produce 320000 watts.
