ATK (formerly Morton-Thiokol) outdoor display in northern Utah, USA. This was a major rocket development facility during the Cold War and beyond.

The mock-up of the hardware described in the caption in the adjacent picture. ATK (formerly Morton-Thiokol) outdoor display in northern Utah, USA. This was a major rocket development facility during the Cold War and beyond. Update: Realizing that the "adjacent photo" no longer contains the interpretive sign, I added that photo in a note. UPDATE 2: This is actually a mock-up of the motor for the Minuteman first stage. It's obviously not 156 inches in diameter!

Bodie, California, USA. Bodie was the first Western mining camp of any size to electrify, in the early 1890s. They built a dam and hydroelectric generating station on Green Creek, in the Sierras, and ran a powerline to Bodie, a straight-line distance of 15 miles or so. The state of electrical knowledge was so primitive that they thought they had to keep the line as straight as possible, because electricity would spill off the corners! This was probably the sort of big motor that ran things like the lathe (next pic) with an external belt.
