18. I've had some experience with biodiesel as well.

I have a Golf TDI and used to make my own biodiesel using used veg oil from a potato chip & taco manufacturer. Did it for several years until the price of canola oil went up and the chip makers started reusing their oil and my source dried up.

I had a fairly large operation for an amateur - buying methanol by the drum and potassium hydroxide by the 50 lb bag. I ran 100% bio without much issue for several years but, I eventually pooched my injector pump seals (which I was fortunately able to replace myself). At the time I could make it for about 25 cents per litre.

Anyhow, yes "wood" alcohol can be produced from wood but I was not aware that a significant amount is now made by that process - maybe that will change.

Biodiesel can also be made from tallow & lard can it not? maybe with greater difficulty and lower yield?

BTW, I had to answer some pointed questions from the methanol supplier - they were suspicious I might be using it in a meth lab.
