First thoughts about Biodiesel

My first thought about the Biodiesel project was "Wow!". "Am I really going to do this?" "How am I going to move the bus?" "This isn't true..." I thought that this project was something that wasn't big and serious as it is and the project wouldn't envolve using chemicals and gases. This project tells me that I will have to create a biodiesel gas that works well and is eco-friendly. The biodiesel gas cannot clog the engine or filter and it has to be able to run a school bus. I will have to create or find a way how to "purify" or "clean" the oil and make my own formula. I started to have some questions while doing the project and some of them were "Will my teacher help me on this project?", "How will we know if we don't do something wrong?", and "What happens if we get hurt during the process?" I would really like to know the answers to these questions.
