I remember John Cohn, an IBM Computer Engineer, was on some TV show called The Colony and built one <a href="https://www.youtube.com/watch?v=bkH6mFlfH3o" rel="nofollow">https://www.youtube.com/watch?v=bkH6mFlfH3o</a> and I seem to remember it getting much further than this clip.
I had no idea these were actually made in significant numbers.<p>>even a modern woodmobile requires up to 10 minutes to get up to working temperature<p>That was my first question, and I can't imagine it would be great to have a parking garage of these things warming up / outputting gasses for 10 min each.
You don't run these inside enclosed spaces, because the carbon monoxide would kill you.<p>It's nowhere near as convenient as gasoline--there's plenty of minding and care required--but during hard times it's much more efficient and convenient than hauling a truck load of stuff by horseback, or walking. A wood gas spark engine runs much more efficiently than an equivalent steam engine, for example.<p>The difference back then is everything was carbureted and switching over to wood gas was relatively simple. With today's extremely complex fuel injected vehicles it will be a whole different story.<p>Converting the wood to charcoal before use has been found to be the most reliable method of burning wood by most users, with lowest contamination/fouling risk, although the owner of the <a href="http://www.driveonwood.com" rel="nofollow">http://www.driveonwood.com</a> forum (a guy from Springville, Alabama) runs his truck on straight hardwood and has put many miles on it like that.<p>When in good tune, a full size pickup truck will go about a mile per pound of wood.
> If, one day, the availability of (cheap) oil comes to an end, the omnipresence of the automobile will be history.<p>I think the years since this was written has shown this to be false. BEVs are steadily replacing ICE vehicles and we have more cars than ever.
I didn't know about this, and initially suspected the article was an LLM-generated prank (photos and all). Now I entered the rabbit hole of water gas, wood gasification, Gustav Bischof, Lowe's gas... HN is such a great place of the Internet!
I wonder if a wood powered tractor for farming would be more practical than a wood powered car for transportation
I think it would, the only problem being smaller row crop farmers who would be mostly likely benefit to implement it or want to implement it have been pushed out of agriculture more and more over the decades and struggle to survive at all. Which makes spending time and money on experimental work like this far less likely.
Check out <a href="http://www.driveonwood.com" rel="nofollow">http://www.driveonwood.com</a> to see plenty of examples of both. A wood car or truck can be amazingly practical for any use involving long steady state (i.e. highway driving), not so much for city use.<p>A tractor can certainly work well on wood gas.
