Biodiesel Basics DVD is a companion to the Biodiesel book. It is a 40 minute tour of Bill Kemp's microscale biodiesel production facility that he designed and installed at his home. Bill takes you through a step by step guided tour of the equipment and method used to make ASTM certified biodiesel. This DVD should not be purchased without the book as it will leave too many unanswered questions that can only be addressed in the book.
