In post war Germany, my dad worked on many wood gas vehicles. Check out Mother Earth News, they had many articles on the method. I still have many of those issues in a tote, might need to dig them out.
Many of the early gas lines in cities and villages were run for coal gas,Before I retired I did some surveying for an old maintenance yard for a local electric company. I’m not sure what was is the ground but they dug it all up. Kind of a strange project I could never figure out exactly what they were doing but the ground was contaminated from an old coal gasification plant.
