Re: [patricio_lintz] Diesel automobiles in Mexico?

I looked at the homebrew diesel, but it requires either ethanol or methanol. neither of which are free, as well as sodium hydroxide. A dangerous, labor intensive process, but I as an engineer, could do it, if I decided that the time and cost were worth it. I am not sure that there is a local source for the WVO. The people down here may juat keep using it until it evaporates. They don't throw much away! I will keep investigating. I'd love to hear what you find out about the WVO in Mexico. There are some places in the USA that don't have any oil to dispose of either, as I found out when I approached donut shops. Apparently the donuts soak up enough grease that there is none left to change. I make the occasional small batch of BD when I'm home, the best oil there comes from Chinese restaurants. True the CH3OH (methanol) isn't free but I do manage to recover almost 90% of it. The recoverable NAOH (lye) and glycerin may be usable in homeade soap. I'm working on soap recipes as we speak. I'm not so sure about using C2H5OH (ethanol) in place of the CH30H. I'm pretty sure that the transesterfication would be similar, but the end product would be an Ethyl ester, and not a Methyl Ester. I'm not sure the two are interchangeable, hmmm maybe. Anyone have the definitive answer here? Labor intensive yes, but isn't labor in Mexico CHEAP? If you find a good supply of WVO, perhaps we might discuss building a co-op. Compórtate bien, y si no puedes, invítame! MG Rabon
