Forgive me if the list has already examined this case. I can't resist sharing it in case it's news. This item is from an environmental news service called Greenwire:

"Justin Carven, a student at Hampshire College, MA, took an interesting route for his senior project. Carven converted a 1982 Volkswagen Westfalia camper van to run on leftover cooking grease. Carven: "The plan is to get some exposure to build up support for alternative technology." The van gets 20 to 25 miles per gallon (Ellen G. Lahr, Boston Globe, July 27).
