You might want to hold off on veg-ifying your Mercedes 300TD wagon, as the new source of waste-based energy may be coming from your kid's day care. Engineers at a company called AMEC are working to use a process called pyrolysis to break down dirty diapers into a cheap synthetic diesel fuel that would cost only 50 cents per liter (a little less than $2.00 per gallon).

The process could work with any sort of trash, but works better when you can keep a consistent material. While this fuel doesn't yet reach the quality of vegetable oil, it gives us hope of a future where we'll be driving a Straight-Diaper-Diesel Golf. No word on whether adult diapers work better than infant diapers. [ CTV]
