The first long underwater tunnel in the world designed for motor vehicle use was built from 1920 to 1927. The 29.5-foot-diameter, 8,500-foot-long twin tubes of this tunnel were shield-driven by the pneumatic method through extremely difficult river-bottom conditions that were overcome by the ingenuity and determination of its engineers, Clifford M. Holland, Milton H. Freeman, and Ole Singstad. They were the largest in the United States when built.

This landmark artifact represents the first commercially successful farm tractor in the world powered by an internal-combustion engine. It was invented and built by Charles W. Hart and Charles H. Parr in Charles City, Iowa, as their Model 3, following two prototype versions.

This 350-horsepower Corliss type steam engine is an example of a typical late nineteenth century steam engine. The essential feature of Corliss type engines is the valves that admit steam to and exhaust it from the cylinder. The Corliss valve gear made the engine extremely efficient in steam consumption and was the most efficient system for controlling low to medium speed engines.
This particular engine operated for more than eighty years, having been retired not by age but over concern for stack emissions by the U.S. Environmental Protection Agency. The engine was built by the William A.

The Hanford B-Reactor was the first plutonium production reactor to be placed in operation. Its success made possible the subsequent development of atomic energy. The research work, engineering, and planning required to make the reactor operate is one of our most advanced achievements. Much of the reactor core, cooling system, shielding, and auxiliary systems were designed by mechanical engineers.

This is an old technology brought here by new immigrants. It represents the beginning of modern life in a hard wilderness. This wind-powered gristmill was built in 1870 by Fred Meiss, Jr., and Otto Fiek near Spring Creek, from parts of the first windmill in the new state of Texas, erected by E.G. Witte. The millstones are the ones Witte imported from Europe and are believed to be one of the earliest sets in the United States to survive.

On April 21, 1949, a completely outdoor turbine-generator was placed into commercial operation at the Greens Bayou electric power plant--the first fully outdoor unit to operate in the United States. The demand for unprecedented quantities of electricity after World War II pressed utilities to provide addition power quickly. The outdoor design, unlike the traditional large turbine hall, resulted in significant reductions in the cost per kilowatt to build the plant.

A variety of mechanical feeders, including drag-chain conveyors and rotary pocket feeders, historically have been used to volumetrically control the flow of fuel to coal pulverizers on power generators. Most power generation in the United States has relied on burning fossil fuels in steam boilers, with coal as the fuel of choice. By the 1920s, pulverized-firing (the burning in suspension of finely ground coal particles) evolved as means to more complete fuel combustion and higher system efficiencies and facilitated the use of larger boilers.

Designed and built by Fred Graue, a German immigrant, together with William Asche, the Old Graue Mill began operating around 1852 and served the village of Brush Hill (Hinsdale) until World War I. Its undershot waterwheel, wooden gearing system, belt power transmission, bucket elevators, and related bolters and sifters were representative of an ancient technology that began with Roman engineer Vitruvius. It ground wheat, corn, oats, and buckwheat in an era that was on the threshold of the Industrial Revolution.

Commercial pineapple production began in Hawaii about 1890. Fruit was hand-peeled and sliced to match can sizes for export. In 1911 James D. Dole hired Henry G. Ginaca to design a machine to automate the process. As fruit dropped through the Ginaca machine, a cylinder was cut to proper diameter, trimmed top and bottom, and cored. This machine more than tripled production, making pineapple Hawaii's second largest crop.

The Georgetown Steam Plant, a surprisingly complete and operable steam power plant after a career of nearly seventy-five years, was built in the early 1900s when Seattle's inexpensive hydroelectric power attracted manufacturers. Much of the power produced at this plant operated the streetcars.
