Hubby has a new vision, anyway new to him. We have access to lots of beef fat and so it says on the net, you can render the fat, add three ingredients and there you have it. Anyone done this? Our farmer neighbor friends are getting all inspired and ready to do this as a group project to run our tractors, engines and generally say nix to buying gas and making our own....biodiesel that is. Are we crazy? smart? simplistic? or are we really on to something? Is it really as easy as it sounds?
