A friend directed me to a post today, and you all have to read it. 

Or anyway, if you like dieselpunk, you should read it.

Aside from my knee-jerk need to point out that steam is not a fuel, the fuel what is burned to heat the steam, and there were, ironically enough, steam engines that ran on diesel fuel, this guy really gets the spirit of the difference between dieselpunk and steampunk. “Steampunk heroes are engineers and tinkerers. Dieselpunk heroes are drivers and pilots.” In a steampunk book, the main character would build an aeroplane from scratch, maybe the first aeroplane ever, and it probably just barely flies. In a dieselpunk story, the main character flies the coolest, most advanced aeroplane their civilization has ever built, and a team of engineers to keep it running.

Now if you’ll excuse me, I need to go buy his book.
