You asked me for Ideas? Sure.

To start with, particle accelerators: They're horrendously inefficient. They don't actually directly produce antimatter, they just smash regular matter to pieces and sometimes some of it randomly gets converted into antimatter. Sometimes. Some of it. And they have to use huge amounts of energy to accelerate it to the speeds they use, yes. Now, some incremental improvements will be made as scientists get a better handle on exactly what speed they need to accelerate the particles to in order to achieve that, and manage to make accelerators tailored, precisely, to that energy level. But...

It should be possible to create some kind of energy field--tiny hyperfocused magnetic fields that would reverse individual atoms that passed through them? Static electricity? Something even more exotic?--that would perform the conversion more efficiently. All the energy is already there; antimatter is not a negative energy state, or we could build alcubierre drives out of it, and if we could do that, somebody would already be posting scientific articles about it. So you don't have to completely counter the mass energy of the entire quantity of matter and basically re-create it, matter-to-energy-to-antimatter, and if that was what you had to do, you'd do better to just leave it as energy in the first place and call it direct matter-to-energy conversion. It should just be a matter of flipping the charges somehow.

So... Call it, say, a quantum field reverser. Because we don't actually know how it would be done, or it would be science fact. But we can make a guess that someday, someone might invent something like this. About the same time as they come up with other things that seem insanely impossible today.

Like artificial gravity, which seems not just impractically expensive in terms of power, but quite possibly actually impossible, yet which is also in this game.

So why not? Instead of fussing about with new ores, which are known to cause problems with asteroid generation (read the comments about deuterium ore in Nukeguard's deuterium fusion mod), use one of your existing models--your reactor model, maybe, since it wouldn't look like a particle accelerator--and rename it as a 'quantum field reverser', or something like that, and make it take, say, four or five hundred megawatts--basically its own dedicated large fission reactor, plus part of the output of a second one--and have it produce a hundred grams every few minutes.

I say a hundred grams because I don't know if the game will let you use increments smaller than that. If you can get it to give you a gram every few minutes, sure. Just remember that, as nice as it is to make things prettttty lifelike in a game (or mod!), it still needs to be playable. Or nobody will play it.

Now, I've mostly limited myself to talking about antimatter, because that's what this mod is about. But why not make a direct matter-to-energy converter...?
