Project

The purpose of this new project is to create gas. Students are to create gas by making biodiesels. When I first heard about the project, I was shocked since it would be a big project. We had to make a biodiesel, purify cooking oils, etc. I'm wondering a lot of things. I wasn't in class for the introduction of the project. My main question would be "How is making a biodiesel result in making gas? I thought only biodiesel engines could produce gas."
