This reaction or "Scotch" turbine had as its antecedent the steam reaction wheel invented in Greek Alexandra by Hero around 100 B.C.. It found widespread hydraulic application in the United States from the beginning of the nineteenth century to mid-century when French-inspired hydraulic turbine design pushed reaction wheels into obsolence.
The glider was the first heavier-than-air human-carrying aircraft to achieve controlled piloted flight. On his first successful flight, August 28, 1883, John Montgomery soared at about 600 feet. The Montgomery glider's success demonstrated aerodynamic principles and designs fundamental to the modern aircraft.
As a practical conveyance during the horse-and-buggy era, the Monongahela Incline was one of seventeen built and operated in Pittsburgh in the last century. Of the seventeen, the Monongahela and the Duquesne are the only two remaining operating units. While the Mt. Washington Incline was known as a coal-carrying incline plane in 1854, the Monongahela Incline is probably the earliest passenger-carrying incline in the United States and has been in continuous successful service since its construction.

When Ford Motor Company introduced its new Model T on October 1, 1908, even an inveterate optimist like Henry Ford (1863-1947) could not predict the vast changes that his rather homely new vehicle would produce. What flowed from this series of bold innovations was more than an endless stream of Model Ts — it was the very foundation of the twentieth century itself. The assembly line became the century's characteristic production mode, eventually applied to everything from phonographs to hamburgers.
This pump, designed by Edwin Reynolds (1831-1909) and built by the Edward P. Allis company, is the major component of one of the earliest water-pollution control systems. It was capable of pumping more than a half billion gallons of water a day, the highest-capacity pump in the world when installed. It still is used during the summer to pump water from Lake Michigan into the Milwaukee River upstream of the downtown area. This maintains a current in the lower portion of the river and greatly reduces the concentration of pollutants.
The Old Mill, a smock type of windmill, believed to be the oldest operating windmill in the United States. Most of its parts are original. This mill is the sole survivor of four that once stood along the range of hills west of the town of Nantucket. The long spar and wheel rotate the top of the mill and turn the sails into the wind. Inside, visitors can watch the gears as corn is ground into meal, producing about 5 bushels an hour. Documentation of the restoration of the windmill is located at the Nantucket Historical Association's Research Center.
Designed and constructed in the early 1940s, this laboratory has an unequalled capacity to simulate a wide range of climatic conditions from arctic cold to jungle moisture. Data from tests of some three hundred different aircraft and over two thousand items of equipment has provided information vital to the performance, safety, and reliability of aircraft operating in extremes of weather.
At the mountain where the Civil War's Battle Above the Clouds was waged, tourist business has thrived from the building of its first toll road (Whiteside Pike) in 1857 to present day.

This wind tunnel complex was developed by the National Advisory Committee for Aeronautics (NASA's predecessor) to serve the emerging need for supersonic research and development following World War II. The three-testing-section configuration covers Mach number .03-3.5 and utilizes a single…Read More
This machine, designed by Alton S. Newell, efficiently reduced automobile bodies into scrap metal for recycling. A body was fed into the shredder at a controlled rate, and rotating hammers, driven by a 500-hp motor, shredded it into small pieces that were easily shipped. The process took about…Read More
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…Read More
This is the oldest operating vessel with a diagonal, compound steam engine, with disc valve gear. Operating at a higher pressure than the oscillating-cylinder engines then used in lake steamers, this type of engine was more powerful and efficient, as well as smaller. The compound engine, built…Read More
Opened July 9, 1904, this lift lock is the highest of its type in the world, transferring boats between two water levels in a single 19.8 m (65 ft.) lift. Designed in place of conventional locks, which would have lengthed the time considerably to transverse a gradual drop, this lift lock was a…Read More
The Pilatusbahn—the steepest rack railway in the world—has operated successfully since its opening in 1889 over a route of 4.62 kilometers (2.87 miles) between Alpnachstad on Lake Lucerne and Pilatus Kulm, rising 6,791 feet (2,070 meters) above sea level. This results in a gradient of 48%, or a…Read More
This was the first successful machine for mechanizing the identification and price marking of retail merchandise. At a single stroke of the operating handle, the machine formed a tag from a roll of stock, imprinted it with price and other information, formed a wire staple, and stapled the tag to…Read More
The economic situation in the whale oil business (for lighting), coupled with the increased demand for lubricants, stimulated growth in the U.S. petroleum industry. The drilling of the heavy, sulfurous, and asphaltic California crude began in the 1870s at the Pico Canyon area, using the…Read More
In the late 1920s, the automobile cut railroad passenger service by more than half. The debut of the Pioneer Zephyr heralded a comeback in 1934, touring the country and being seen by some two million people in 222 cities.
The Zephyr was the first diesel-powered, stainless-steel…Read More
Used to lift molten iron to molds where it was cast into pipe, jib cranes were the sole means of conveyance in the pit-casting process. When pit casting was replaced by centrifugal casting in the 1920s, many pits were filled and the cranes were used to produce cast iron fittings or general…Read More
The Port Washington Power Plant of the Wisconsin Electric Company was the most thermally efficient steam power plant in the world for many years following its opening in 1935. Its design reflected the cumulative experience of the utility's engineers in burning pulverized coal at the Oneida…Read More
Steam and the inexpensive electricity it could produce brought about dramatic technical growth in the United States. Developed during the last century, reliable and efficient steam engines were the forerunners of today's massive generating facilities. A rare survivor of the period, the Pratt…Read More
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.…Read More
