This is an old pickup with a crazy looking contraption in the bed of the truck composed of ducting, PVC pipe, a 50 gallon drum, an old furnace, and of course, a lot of duct tape among other many other things. It was a wood burning oven that catches the combustible fumes from the wood coals, condenses any moisture, then feeds the fumes into the engine to make it run. If this is for real I might have to do it to my Bay Window Bus if fuel keeps going up the way it is...
