coal monoxide is a slow burning gas I've never seen anyone refer to CO as "coal monoxide" before.

It looks like the author's first language may be Dutch, where carbon monoxide is "koolmonoxid" and "kool" can mean both "coal" and "carbon" (although there are more specific words for coal such as "steenkool" = "stone carbon").

Important downside explained half way through: "if we were to convert every vehicle, or even just a significant number, to wood gas, all the trees in the world would be gone and we would die of hunger because all agricultural land would be sacrificed for energy crops."

In the last years of WW2 I think Japan chopped down the last of its trees to make a bit of aviation fuel.

Wait, what? There's absolutely no evidence that "Japan chopped down the last of its trees". Why would you say such a thing? You enjoy lying on the internet?

Nice thing about wood power is that as long as you have a sustainable source of wood, you're 100% solar-powered and carbon neutral. That is to say, it's a source of energy that is (can be) non-fossil, nor derived from any fossil sources, and which recycles it's own CO2 emissions. There are very few other alternatives that can claim the same. Perhaps Hydro? Solar panels don't offset their construction CO2 costs, and i…

I have never seen a discussion about the real sustainability of biomass but I would be curious to know something. OK, the CO2 it emits gets recycled and in a stable biomass-burning world cycle, more CO2 will be emitted but also more trees will grow so it should balance out.

Would that not, however, durably increase the baseline CO2 levels? Sure it is sustainable but do we want to sustain a 500 ppm level? Where would it bring us if the whole world switched from oil to wood?

Same in most Germanic/Scandinavian languages I believe. Carbon and Coal are synonymous.

Coal as in coal power, coal barbecue, and the element carbon use the same word. That’s not a coincidence.

Apart from some exotic forms like diamonds, trees or rabbits (less pure), coal is how we normally encounter carbon.

There is not enough wood to switch over from fossil fuels anyway. We burn incredible amounts of coal and oil.

In German "Kohle" means coal, and "Kohlenstoff" is carbon. It's not the same word.

(But carbon monoxide is "Kohlenmonoxid")

In Russian, Carbon is "Uglerod", whereas coal is "Ugle". CO, when not referred to by its colloquial name, would be "Uglekislorod" - literally, Coal-oxide.

I saw some of these in use while visiting DPR Korea. We weren't up close, but the government tour guide confirmed that they were wood-burning trucks. Sadly I was not allowed to photograph the trucks. Like the article mentions, deforestation is an issue they can cause, something Korea suffers from greatly.

When resources were scarce during WW II in Germany there were various kinds of wood gas vehicles. Here is a video of a 1942 tractor: https://m.youtube.com/watch?v=RMVwbjp514o

From what I heard, it was the same in France, with various vehicles converted to use wood gas too.

Energy crops (subsidized by the government) has already replaced agricultural land for Ethanol fuel production, up to 1% of cultivated land worldwide being use for it.
