Seems like it would be ideal-ish for deathmobiles, it’s no totally broken though since it requires stopping to process wood on a VERY regular basis.
I’m not sure what the code to handle it would look like though, it requires having “tanks” containing wood, restricted rate of fuel consumption and lowering power output of the engine compared to gasoline.
It would be a lot simpler if we required conversion of a gasoline engine directly to a wood-burning engine, with dedicated wood tanks.
