Nicolas-Joseph Cugnot invented this fardier à vapeur in 1770. It was a three wheeled steam powered transport developed for the French Army, who was looking for something to haul cannons around. While it had all sorts of drawbacks (you had to fill up its water tank every 15 minutes) it actually worked, and would go several miles per hour while loaded with a few tons of stuff. He got a pension from King Louis XV for this.
What's cool is that in 2010 some students at ParisTech (yes, there is such a school although they likely have never gone to a Bowl Game) built a working model from original plans. The public unveiling starts about 2 minutes into the video and while the music is more than a bit annoying the fardier itself is tres magnifique.
