that uses actual footage of that time I will look at  the cars and see

All the best.

During WW2, many german civil cars were operated on wood gas. The wood  
is heated to 800 degree celsius and starts to burn without oxygene, it  
converts to charcoal. The wood gas is 50% carbon dioxide , 33% carbon  
monoxide, 10% methan, some ethen and hydrogene. A special driver  
license was required. What lef the exhaust is anything else than  
environmental friendly.
