How about this for a vegetable oil powered generator?
Man, if I had this I'd have to just sit and watch it run for awhile, every day! While generating electricity, of course.
I guess I'm better off with my Lister, though. This thing makes 52 horsepower. I would have to build more structures, just so I could air condition them! Of course, as slow as it is, I could probably get it to run on sawdust!
