Not only is Willie Nelson into Biodiesel, but he has an entire webiste and business devoted to it.  One of their selling points is that biodiesel is fuel that is a fully renewable enrgy source, it is grown right here in America, and it supports our farmers.  I think this is a great way of looking at it and it ties right in with all of Willie Nelson’s efforts with Farm Aid.  The site has some really good information, I learned a bunch the first time I visited it.  Good ol’ Willie….
