Also, the PR problems any strike could cause are likely bad.

Hello Saber964. I just read this and I was wondering how economical this was for your friend? Was the money he saved on fuel actually enough to pay for his expenses in making the moonshine? Or was he doing it at a financial loss out of ecological concerns? |

There are a variety of ways in which one can convert vegetable oil to biodiesel. All of the ones I am aware of suitable for DIY operation use either acids or bases to crack the oil molecules. I've made biodiesel from used cooking oil and while biodiesel has a number of advantages, it does require a certain amount of care in it's preparation. The process I used required dry pure lye to be mixed with methanol; the resulting methoxide is highly toxic and can be absorbed through the skin, so proper protection is essential. Properly processed and washed, biodiesel does make very good diesel fuel, with a high cetane rating, high lubricity, and no sulfur. There are two major pollutants resulting from ULS Diesel operation, NOX and particulates, and biodiesel burns at a lower temp than many petrodiesel, reducing nitrous oxides (NOX), and has a high cetane rating, keeping the particulate count lower. Processing oil into biodiesel renders the smell from cooking oil much less noticeable, and at least here in the USA, there is no requirement that you dye it. ![]() ![]() |

Yep! Upper Flammability Limits are awesome. One reason the current diesel process is 'complicated' is the quality. If you give up some on the quality aspect (blending), different chains, different (are you familiar with octane?) ratings to reduce pre-detonation, then you can accept a much wider fuel quality tolerance. So essentially a crude distillation column can break things down- there's no reason they can't refine those materials further to better grades. It's just time. Recycled heat can do a lot to improve that too. Catalytic cracking might be way off, but they already have gold and silver and copper. Separating out platinum or rhodium might be impossible without electricity, but most of these metals were isolated with just chemicals. I suppose any scientific journal that described the crude way people isolated elements could be reproduced in the technology constraints. Not a lot, and not fast, but doable. |
