2 full size railcraft tanks full of oil now and only on my 4th remote oil well. 2 36HP boilers running on fuel, burning almost nothing at full heat. Next project, biofuel from forestry. Anyone know how many tree-farms per squeezer per fermenter per still and that sort of thing? I guess I'm asking the basic number of each machine in a biofuel setup to keep it all running and not have too much extra of any one thing.
