    I think they can make biodiesel using previously used vegetable oil. Basically get the used stuff that McDonald's uses to make fries, blend it in and voila! Wouldn't need to be diverted from food at all.

    vegable oil and used vegetable oil require seperating the glycerine or goo from the oil,not very practical as a replacement.i think we can be a little more genius in diesel alternatives,ive seen diesel engines run off of used oil,used transmission fluid,aftershave,kerosene and jet fuel,infact diesels can run off of nearly anything similar to oil so long as its combustible at high compression.

    i think weve only scratched the surface of what could be run in a diesel engine,but i dont see america eating enough french fries to power everything,i could be wrong though the way fast food is growing we might have to convert used cooking oil just to dispose of it.

    That's all true beerftw, and used fryer oil would hardly make a dent in the oil supply. Unless you separate the glycerin, you can only use the WVO in a hot engine because the glycerin will gum up the injectors. Even then, you can only use it in older common rail diesel engines, which is why old Mercedes Benz cars from the 80's command so much money in the used market because they are ideal for such "greasel" conversions.

    Because of the very high pressure that diesel fuel is injected with into the combustion chamber nowadays, it's really no longer true that you can burn practically anything in a diesel. Those extremely high pressures help to atomize the diesel better and make a more complete burn when it ignites from the hot compressed air, and thus have allowed diesels to become more efficient and significantly less polluting.

    I think a couple of people have already pointed out the process, but do you think we could actually make a measurable dent in our diesel fuel consumption from fast food resturants? Diesel is used for tractors and harvesters, semi trucks, trains, mixed with karosene and naptha (if I remember right) as part of making jet fuel, RVs and Diesel pickups (used for RVs, hotshot rigs and small deliveries), delivery trucks and personal automobiles. While the total produced by fast food recycling into biodiesel might help with the passenger cars and some RVs, there just is not enough from that source to make an appreciatable difference in out National Daily consumption of Diesel. We need massive amounts of it, and that would mean using corn, soybean and other vegetables to make it.

    Does anyone know if you can make Biodiesel from a Yucca Cactus? If so, that would go a long way towards a good supply. Think of the Desert Southwest where most of the land is useless without massive and costley irrigation, yucca grows there.

    yuca plants and joshua trees used to grow native where i was in cali,im pretty sure yuccas are a protected species and i know for a fact even damaging a joshua tree is against federal law.
