Following on from a post I made on one of Mick's (Son of a gun-ner's) recent weave of threads, a bit of 'net rummaging later, and I found this vid on the theme of German Tigers- powered by wood gas. I'd not been aware of how widespread this practice was, but
had wondered where all their oil had come from, when they'd lost access to oilfields in Rumania and the East, and were being bombed into oblivion..

Germany was never oil-rich in the first place..but had some very nice Black Forests

This Tiger would make an interesting project..
