Am I right? Alligator powered trucks? Like, big ol’ trucks with alligators trotting along on treadmills? Or harnessed like vertically challenged oxen? Or with their feet sticking through the floor of the trucks, running all Flintstones-style?

Oh, wait, none of those things. Ha ha ha. My bad. Alligators will actually power trucks by being rendered into diesel fuel. Laugh out loud.

Or, at any rate, alligators could be rendered into truck-powering diesel fuel. There aren’t necessarily any plans to do so.

The idea to render alligators came from a recent study authored by researchers form the University of Louisiana and published in Industrial & Engineering Chemistry Research. Most of the 700 billion gallons of biodiesel produced in this country each year come from soybean oil. As we increase production of biodiesel (we consume 45 billion gallons of diesel every year), some people are concerned that using soy as a feedstock will cause the price of food to increase, so scientists are on the lookout for alternative products to use for biodiesel. Alligator fat, it turns out, is pretty nicely suited to be turned into diesel—it has the right chemical composition, and requires less processing than many other feedstocks.

Are alligators taking the place of 19th century sperm whales as a living source of fuel oil, you ask? When does the scouring of the swamps begin? Weeeeell, sort of never. I know you’d like to go make your fortune by hunting alligators for their sweet, sweet fat, but the study is only proposing using fat from existing alligator farming and hunting operations. Apparently, the alligator meat industry disposes of about 15 million pounds of alligator fat every year. While processing that quantity would only make a very small dent in current biodiesel production, it’s still much more efficient than dumping it in landfills. And it’s much more hilarious.
