Nifty video of a home-built “stratified downdraft gasifier,” a.k.a. a wood-gas generator. Wood gasification was an important 19th century fuel technology, but was finally displaced by petroleum-based gas. Wood gas made something of a comeback during WWII, borne of necessity. It may come back again, after the apocalypse, when we need to try and outrun the Main Force Patrol on our way to Thunderdome. Just pray we can stoke enough chairlegs and clapboard to get us all the way to Bartertown.
