This $200 Wood Gas Generator Powered a Million Cars in WWII (Science Explained)

More than one million cars and trucks once ran on burning wood instead of gasoline, and a barrel sized wood gas generator is the forgotten machine that made it happen. Producer gas carries only about 5.7 megajoules per kilogram against 44 for gasoline, so these wood burning vehicles lost roughly a third to half their power, yet during the Second World War Germany alone kept around 500,000 of them on the road. This video breaks down the real physics of wood gasification, why the same carbon monoxide that powers the engine is the gas that kills people in closed garages, and why a working downdraft gasifier still beats a blackout when the grid and the fuel pumps go dead. Wood gas, also called producer gas or syngas, is made by burning wood with almost no air so it breaks down into carbon monoxide and hydrogen instead of turning to ash. We cover the French engineer Georges Imbert and his 1920 downdraft design, the FEMA emergency gasifier plan from 1989, the honest reason this technology was abandoned the instant cheap oil returned, and how a roughly 200 dollar build bolts onto a generator you already own.
