I'm not terribly worried about what fuel type to use, thanks for the info anyway. I could get enough out of a piece of coal just using the new dungeon loot capacitors found in dungeons and worldgen structures such as Pyramids, Jungle Temples, and other types of worldgen structures. I just want to know why the EnderIO generator doesn't show up in the list whenever I ask JEI to show uses for a piece of coal, as it seems like a bug or issue to me.
Also, wouldn't lava be better off piped into a tank for storage buffering and piped into the EnderIO Combustion Generator through the tank's own I/O system? Or does that not take lava as a liquid type? I prefer solid fuels anyway, less risk of spillage of lava in a base, kind of hard to clean up without burning oneself!
Cheers ...
