I was traveling in Michigan this past week and took a day to visit the Henry Ford Museum of Innovation. All I can say is, WOW! Together with the adjacent Greenfield Village, well worth the visit.
The Innovation Museum offers great displays of engine technologies, including the oldest surviving steam engine in the world, a 1760-ish Newcomen engine, which was given to Henry Ford from the Earl of Stamford in 1929. The photograph is of me standing next to this large machine. The fact that these displays were just one part of the larger museum is remarkable. Again, well worth the visit.
