Thanks to Alex and his love of Piebald, I present the GreaseMobile.

It\’s a vehicle that is completely green. A diesel vehicle that runs on vegetable oil. Apparently, restaurants and other stores throw out gallons of grease each day. So inspired by that waste, someone designed a GreaseMobile. Instructions for conversion is on the website.

I question its effectiveness. What are its tradeoffs? How does it compare with other fuels? At the same time too, does it create pollution? How safe is it?
