#Syngas

In 1921, there were more than 25 million horses in a United States populated by less than 110 million humans. I’m not a mathematographer, by any means, but I think that puts us at a ratio of about one horse for every four-ish people out there. And, just like there are many kinds of people, there are many kinds of horses, too. There are Quarter Horses, paints, Arabians, Appaloosas, and – of course – Thoroughbred racing horses.

Something strange has happened in the last hundred years, though. There are a lot more people and a lot fewer horses, for one thing – just 3 million horses for a whopping 330 million Americans – but it’s a curious thing that there are a lot more Thoroughbreds in 2021 than there were in 1921. What’s more, it’s almost certain that the meticulously bred horses spending their 21st Century days in luxurious stables are serving a vastly different purpose than their hard-working forbears.

You see where I’m going with this, right?

The autoblogosphere is abuzz with the topic of “ rolling coal“, apparently the practice of some diesel pickup truck enthusiasts who fiddle with their fuel systems so as to produce voluminous clouds of dense black, sooty exhaust smoke. I have to admit that when I first saw the phrase “rolling coal” in a headline at Jalopnik I thought it had something to do coal gasification and running cars on wood gas or syngas. After finding out that rolling coal wasn’t what I thought it was, I did look into the history of powering motor vehicles on wood gas and ended up finding out about these rather odd looking cars and trucks known as gas bag vehicles. Frankly they’re more interesting to me than whether or not pickup truck driving bros are blowing smoke in the faces of Prius drivers. I believe that you’ll find these vehicles interesting as well.
