This guy is an ASU professor who built a custom motorcycle that runs on biodiesel that he himself processes from used cooking oil... I was hoping to meet him at his home and get shots of him in his garage (for some reason I pictured him having a crazy laboratory-looking set up in a garage), but he told me he doesn't process the fuel at his home and that he preferred to meet at a Phoenix Starbucks... So I settled for the alley behind the coffee joint.
