This truck gets about 1.5 miles per pound of wood, and can run on trash, wood, grass, cow dung and just about any other dry organic material. This is called gasification and is a easy way to make fuel for a vehicle or generator, this simple design can be made at home with easy to find materials. This was the very first time the system had been used, so the constant turning of the starter is only needed when you are first tuning the valves, once tuned the truck started very quick.
