(Newser) – Mexican pig lard, Alaskan fish oil, and lots o' fast food grease powered what two professional kayakers are calling the longest road trip ever made without gasoline. The 21,000-mile trek from Alaska to the tip of South America—in a converted Japanese firetruck—took nine months, with the duo stopping frequently to give talks on the virtues of biofuel.

Twenty-somethings Seth Warren and Tyler Bradt aren't done: they're rejiggering the truck to drive across the U.S., this time on algae. Warren says he wants to show people they can run cars on all kinds of oils. " We don't think vegetable oil is the answer to all the world's problems, but it's definitely one of them."
