We were pleased to report in “Homemade Motor Fuel Through Wood Gasification” that our experiments concerning the use of wood scraps for vehicle motor fuel showed promise. But little did we realize, at that time, just how well the unlikely form of “solid” energy would work in a “liquid” world.

We’ve come up with an effective alternative fuel power system with a fair amount of cutting and welding. Not only does our wood gas truck move down the road as smoothly and reliably as any conventionally powered automobile, it does so at zero fuel cost!

A Straightforward Process

Here’s how the system works: Wood scraps (we use chunks that are larger than sawdust or shavings, but smaller than a 6″ length of 2 X 4) are contained in a modified hot water tank, and rest on a cone-shaped, cast-refractory hearth. The recycled vessel is airtight except for a spring-loaded and sealed fill lid, a capped lighting aperture, and an inlet port (the last is simply a two-inch brass swing check valve, which allows the “draw” created by the engine to pull controlled amounts of air into the firebox).
