I've succeeded and I've failed at making ethanol biodiesel. I would second what Keith just posted, but suggest that you hang on to that 200 gallon water heater- it'll make a great and (for a homebrewer anyhow) extremely large biodiesel processor someday, if you decide to work on such a scale (heating times becomes an issue, as does oil collections, and any failures you have become a bigger deal since you'll have invested more oil, methanol, and energy into anything on that scale.) Large water heaters are a really good vessel for the advanced stuff. In the meantime get comfortable with liter batches and then upsize a few times. good luck, mark
