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.

Between its opening in 1888 and the mid-1920s, Georgia Tech took a leading role in transforming mechanical engineering education from a shop-based, vocational program to a professional one built on rigorous academic and analytical methods.
Led by John Saylor Coon (1854-1938), a founding member of ASME, this curriculum merged theoretical understanding with practical experience. By bringing Coon on board so soon after the school's founding, Tech began this transition almost from day one, even though it took three decades to completely effect it.

The Garfield Thomas Water Tunnel is a unique experimental facility for hydrodynamic research and testing. The 48-inch (1.2-meter) diameter water tunnel enables the research staff to conduct basic and applied investigations in the fields of cavitation, hydroacoustics, turbulence, transition, hydrodynamic drag, and hydraulic and subsonic turbomachinery. Instrumentation and testing methods have been developed to study noise, vibration, vehicle dynamics, and the interaction between the propulsor and vehicle body.

This fusion-welded drum, tested during 1930, was the first in a series tested at Combustion Engineering Inc. that led to the industrial acceptance of welding for the fabrication of boiler drums. Replacing riveting for steam power plants, electric arc fusion welding permitted increased efficiencies through higher working pressures and temperatures and fabrication of larger units of improved safety. Welding was then rapidly extended to fabrication using optimum alloys for pressure vessel and structural application.

The historic Folsom Power House #1 marks one of the first successful uses of hydroelectric power in the world and the first successful transmission of power long distance (twenty-two miles to Sacramento). The old Folsom Power House still shelters the machinery generated to drive streetcars and illuminate the city of Sacramento.
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.

The F&CH Cable Railway, which opened in 1887, was designed and built by civil engineer Howard C. Holmes (1852-1921). The line is an amalgamation of the Powell Street Railway and the Park and Cliff House Railway. It was one of the most complicated cable-car systems to run from a single station and had been under construction two years prior to its opening.
Andrew Hallidie, a wire rope manufacturer, devised the first operating cable car in the United States in 1873, which ran on Clay Street hill.

At a time when steam power was finding its first uses in America, Philadelphia opened two steam pumping stations, January 1801, to lift water from the Schuylkill River and distribute it through the city's wooden pipes and mains. By 1811 a new water power works was begun on the river near Morris Hill, and the Fairmount Water Works opened September 7, 1815. These water works represented the first large-scale application of steam pumping to water service in the country.

This outboard motor, designed and built by Ole Evinrude (1877-1934) at the Evinrude Motor Company in Milwaukee, Wisconsin, was quickly accepted by the boating public of the United States. Bess Evinrude called the prototype a "coffee grinder," but it moved a boat through water better than the huge steam- or foot-driven motors available in 1907. She encouraged him to build and sell ten, then twenty, soon resulting in the redirection of their automotive equipment business to outboard motors.
