Well, actually I have some experiences with DOW, but without the detour of gasification
This little loco was built in 1939 as a tramway loco. It was rescued from the scrapyard in the 60s, modified with a tender and spark arrestor to burn wood and is in service at the castle garden railway (Schlossgartenbahn) in the city of Karlruhe since the 70s. Burning only wood since then!
I’m a fireman and driver since many years now in the spare time. The little light blue car was my Trabant (sold it to a friend), built in former eastern Germany. Quite funny to drive. With its 0.6 litre 2 cyl. aircooled two-stroke engine, it is a bit different to what you V8-guys are used
The bigger loco only burns wood during firing up the boiler. The trailer load is half the amount you need for one firing up the boiler. The grate area is 4 square meter. you can have a picknick in the firebox with a bunch of people. I’m also a fireman and driver and made a driver’s licence for mainline-service in my spare time. Quite time consuming. This is one of the reasons why I didn’t had time to build a gasifier so far.
The old Land-Rover Series 2 from 1961 is also belongs to me. This will be my “victim” for gasification. No race car even with gasoline, but the low rev. 2 1/4 litre engine will give enough power to move along. In Germany, there are no emission controls for cars built prior to 1968. This legal loophole allows the use of a gasifier. Well at least, the emission laws are not the limiting factor in this case. Still not easy, the regular vehicle safety checks are very strict here, but principally doable.
Sorry for being a bit off-topic
