It's worthwhile to note that fermentation is a pretty resource cheap process. You're not guaranteed to use up the ingredients in (I think) any step, so you can get quite a bit out of it. If you start using sheared (or MFR harvested) leaves for the 2nd step, you'll get way more ethanol crystals than you can use. Another nice thing to note is that you can pulverize sugarcane for 2 sugar.
I don't get why people are so adverse to gasoline engines. Once you have a little bit of fermentation done, you'll really never need ethanol crystals again. I had my fermenters automated just with hoppers and DC engines, and I built up a massive surplus while I was running about half a dozen gasoline engines.
You also really don't need that much lubricant. Just running a gasoline engine for a little while on a grinder (and pumping out the liquid, preferably) will get you more than you'll ever need.
