Grease as Gas

Finally, a fuel for the environmentally minded foodie: Greasel. The Slashdot thread on this system for turning fast-food grease into diesel-engine fuel offers some real classics:

To get fuel for the next stop they dropped by the local Chinese take-out place and relieved them of some of their waste grease. They pulled out of town leaving an exhaust trail that smelled like shrimp fried rice.

I worked at a McDonalds in high school (about 1991), and one of the maintenance guys had an old (even then!) mid-1970s VW Rabbi (someone chiselled off the T for the fun of it) which was running on used shortening. . . . [T]he car - and I mean *the whole car*, from interior to exhaust - smelled like Chicken McNuggets. Sometimes, Filet-O-Fish.
