Year 197 of the Resurrection Era
The super-dense magnetic ring storage technology has been put into production. Replacing your lighter magnetic rings, simply made of alloyed iron, with new elements that are six or seven times more dense with the same amount of frictionless rotational energy stored has greatly increased your storage capacity. Moreso, the Threemind advised that the large store of BAG was more then sufficent for what little storage-solutions you needed to manufacture, meaning the rest could be put towards other high-energy uses.

”I never thought in my life I'd be able to stand in a fusion reactor. These new ultra-dense stabalizers and containment fields make them this safe. Truly remarkable.”
“It is still, erhm, not advisable, erhm, the effects of being exposed to solar radiation even while safely contained is umm... not fully understood... your uhm... Majesty.”
”That's why I made you come in with me! You discovered it. So if it ends up killing me, it'll kill you too!”
“Eeep!”
”...Speaking of which, Ribbonfin, right? Your file says you were manually promoted past normal systems like, twice already? It usually takes a few decades for someone to earn a serious promotion.”
“Yes, Sire. Twice in three years.”
”Well consider this the first time. You're the Science Overseer now.”
“Oh... thank you, your Majesty.”
”Get working on the Mark 3, got that?”

With your existing fusion cores, especially the ones in the warfleet, getting upgraded with new stabalizers and energy capture technology; you're feeling even more ready for the next stage in your plan.
