I modified my blaze cake farm (https://createmod.com/schematics/blaze-cake-farm-2) to make bioethanol. Bioethanol is basically just liquid blaze cake so it can be made infinite. This factory stores bioethanol in a 20*20*25 area (when it is full you can pull out infinite fuel using hose pulley).
At first i was like "Why not use a fluid tank ?" and after a little thought, I just passed on the dripstone+cauldron part, and hooked the lava tank on my infinite lava source.
Nice fucking idea to make it an infinite source ! :D
