Well, you might want to make a TL:DR for this. 4-5 minute video of someone talking, well yeah. Just saying
Now, onto the idea itself: You mine crystals/ore, refine it a bit, and put it into ships. It acts like a giant fuel cell, converting crystal into energy as needed. Or at least that is what I got out of the video.
In terms of a supplement to the energy of larger ships, yes this would be great. However, I would still like the xm3.4 reactors to stay around, as the base power system. This crystal fuel cell would be something more powerful, but would require these crystals. Hopefully changes will be made so that fielding a large ship would require the crystals, and would mean that factions would have to decide, do we want to feild our titan in battle, and use up half our crystal reserves.
