Cugnot's Artillery Wagon

The original was built in 1769, and holy cow, that is 250 years ago.  It was innovative at the time because it used pressure to move the pistons, rather than a vacuum from condensing the steam.  It used ratcheting devices instead of cranks to turn the wheels.  Much of the original machine is still in existence, but it never was put into use and is just a neat curiosity in history.  It should have been much more.  Thank You, Merle for picking this good video!
