the plan, though I dont know what the state of it being put on the “to do soon list” was to have different quality of fuels, with the current oort-shard being the least energy dense.
aka we wont give you more fuel slots, but we will give you higher density fuel where 1 “concentrated oort shard” or whatever is worth 10 oort shards for sake of example, so that the current 891 limit on oort shards in the slot effectively becomes 8910 in this example.
