So, reading through the thread, and seeing a few LPs, everyone seems to love Mob Essence+Gunpowder in a Reactant Dynamo as their pre-Reactor power source. I'm curious why no one seems to use MFR BioFuel. Did a bit of testing, and the BioFuel Generator (contrary to the wiki) generates more RF/tick, and 1 bucket of BioFuel generates roughly 800k RF, as opposed to 500k for 1 bucket of mob essence. Considering that you can make something like 500 buckets of BioFuel with 6 stacks of raw material (I use vanilla seeds, carrots, potatoes and 3 random HC seeds), it seems to be the obvious choice.
Am I missing something, or is it simply that the generator is gated behind blaze rods?
