I found this place about 0.5 miles from my work! Aparently, owner Rob Del Bueno is very knowledgable about biofuels and has a very informative site, http://www.vegenergy.com
From Vegenergy, you can purchase already made biodiesel. Or, for $50, Vegenergy is offering a 3 hour class on the ins and outs of biofuels, and you can get hands on experience with cars that are already converted and learn how to process your own biofuels.
For all those interested in the local area, just thought I'd toss out that people are really doing this stuff!
Oh, gosh, I'd love to do that. I still need to get a junkyard deisel and set it up WVO just for testing, but how neat to do it and teach like a class or something. ****, anyway selling a vw rabbit diesel around south jersey? Rusted out and cheap prefereable, :-). Hehe, I love grease.
