Home Made Biodiesal is Dangerous
This website should pull its articles and information on biodiesel. What it is recommending is dangerous for people and and the environment (not to mention the diesel engine).
Please read Bill Kemp's work: "Biodiesel and Beyond."
Note, that he produces biodiesel in a lab and deals safely with the waste stream, not in your kitchen where the waste is flushed down the drain to harm the environment.
