I was just poking around in NEI, looking for more stuff to add to my factory, and I came across this little gem. Apparently it can be used to make biofuel at a 2:1 ratio, which seems pretty snazzy. The only problem is that it requires 16 advanced machine casings to go with it (which translates to 48 chrome, or 432 rubies). The EU investment per operation (16 biomass cells into 8 biodiesel cells) is quite modest, though, only 12,800 EU, and it only takes 20 seconds. Does anyone have any experience using this?
