Between 1825 and 1847 the State of Ohio constructed 1,000 miles of canals and feeder canals, 33,000 acres of reservoir surface area, 29 dams across streams, 294 lift locks, 44 aqueducts and many smaller structures at a cost of about 16 million dollars. The network of navigable canals provided a system of economical transportation where none had previously existed; the young state, with its isolated frontier lifestyle, was transformed almost overnight into a thriving segment of the nation's economy.

The convenient dry-copying process for printed pages is among the truly revolutionary inventions of the century. In 1937 Chester Carlson, a New York patent attorney, developed the concept of applying an electrostatic charge on a plate coated with a photoconductive material. On November 22, 1938, Carlson dusted powder dyed with evergreen spores across an exposed plate and transferred the imprint to the surface of a paper.

Located at the northern tip of Michigan where Lake Superior, Lake Michigan, and Lake Huron join together, the Sault Ste. Marie Hydroelectric Power Complex was built to harness the hydroelectric potential of the 20-foot falls at the headwaters of the St. Marys (sic) River, the sole outlet of Lake Superior. A century after its construction, the plant remains the largest low-head hydroelectric facility in the United States. Today, the Sault Ste. Marie plant supplies electricity to area residents, especially those in the Upper Peninsula of Michigan.

The first authenticated discovery of gold in the U.S. occurred on the Cabarrus County farm of John Reed in 1799, sparking the nation's first gold rush. During its peak years, more than a million dollars of gold was recovered a year, making North Carolina a leader in gold production until 1848. This mill, built by the Mecklenburg Iron Works of Charlotte, North Carolina, is original except for the timber work. Two groups of five 750-pound stamps with 5- to 7-inch lift, rose and fell thirty-five times a minute to yield a finely crushed ore.

No image dominates the Midwestern landscape like the monolithic grain elevator, whose present shape and construction owe much to grain company operator Frank Peavy and architect-builder Charles Haglin.
Wanting to improve on the flammability and cost of traditional wood-cribbed construction, Peavy speculated that reinforced concrete, in its infancy at the turn of the century, would outperform other materials. But critics feared that the elevator would collapse due to the vacuum created when grain was emptied from the air-tight structure.

The N.S. Savannah was the first nuclear-powered cargo-passenger ship, built by the New York Shipbuilding Corporation at Camden, New Jersey. The 74 maximum-power thermal megawatt pressurized-water reactor was supplied by the Babcock & Wilcox Company. Nearly 600 feet long with 22,000-tons displacement, the ship at top speed surged along at 24 knots, with more than 22,300 shaft horsepower to a single propeller. A joint venture by the U.S. Maritime Administration and the Atomic Energy Commission to the design of George G. Sharp Inc.

Squeezing an orange for juice is part of the concept of this machine, only on a much larger scale. The extractor revolutionized the juice industry. The twenty-four head rotary action simultaneously extracts juice from the interior of the fruit and citrus oil from the peel surface. The first unit was operated experimentally on grapefruit at the Sunkist Exchange plant in Tempe, Arizona, during late May of 1946. Tests on citrus fruits continued in California, Texas, and Florida.

While Thomas Edison perfected the first practical and durable filament in 1879, it was not until much later that electricity left the laboratory to become the universal source of light. This required a tremendous number of glass envelopes for light bulbs. In the 1890s the top speed of the finest glass-blowing team produced two bulbs a minute.

Nicholas Montgomery Powers built the bridge. It was first constructed behind the village, then taken apart and reassembled over the stream. Some residents questioned the idea of re-constructing it, but Powers was so confident of the bridge's durability that he sat on the roof when the final trestles supporting it were removed. From his perch he reportedly said: "If the bridge goes down, I never want to see the sun rise again!"
