BIODIESEL

Do you know that the oil used to fry fish, French fries, chicken, etc. can be collected and then used as fuel for cars, trucks, and other vehicles that have diesel engines? All you have to do is to pass the used cooking oil through a fine filter to remove the very small food particles and then add a little lye and and then a little methyl alcohol (methanol) to remove the glycerin from the cooking oil. After an aging period of a day or so, you now have an organic, biodegradable, non-toxic fuel that's called biodiesel. Read the Wikipedia article on biodiesel and then explain in your own words why vegetable oil or biodiesel could be a good alternative to diesel fuel to use in passenger or commercial vehicles.
