Biodiesel is still a relatively new concept to most people. Although research on this subject has been going on for quite a number of years, not much has been promoted to the general public as to how it is made and how it works. Generally, it is accepted that Biodiesel is a natural form of fuel, but what is it that makes it a natural fuel source?
