The St. Charles Avenue Streetcar Line is the oldest surviving interurban-urban passenger rail transportation system in the United States. Originally incorporated as the New Orleans Carrollton Rail Road in 1833, service began in 1835. A variety of motive power had been used including horses, mules, overhead cable, steam engines, and ammonia engines before electrification in 1893. The 900-series cars presently in service were designed and built by the Perley A. Thomas Car Company of High Point, North Carolina, in 1923 to 1924.

The two 3,500-hp steeple compound Unaflow steam engines powering the S.S. Badger represent one of the last types of reciprocating marine steam engines. Built by the Skinner Engine Company, most Unaflow engines are single expansion. These feature tandem high- and low-pressure cylinders separated by a common head. The Badger's four Foster-Wheeler Type D marine boilers, which supply 470-psig steam to the engines, are among the last coal-fired marine boilers built.

The SS Jeremiah O'Brien, an emergency cargo vessel of the type EC2-S-C1 better known as Liberty Ships, is one of two operative survivors of 2,751 ships, the largest fleet of single class ever built. The other is the SS John W. Brown, now in Baltimore (not operative at the time of the landmark designation). Between March 1941 and November 1945, eighteen US shipyards produced 2,751 ships. The design stressed minimum cost, rapidity of construction, and simplicity of operation. The original design and configuration have not been altered.

George Washington's concern over standardization of rifles for the Continental Army led to the formation of national armory and to his selection of Springfield as its site. Completed in 1794, it was the first national armory in the United States. Like the Robbins and Lawrence Armory, the Springfield Armory was an outstanding machining center for the design and mass production, employing notable engineers such as Thomas Blanchard (1788-1864), Thomas Warner, and Cyrus Buckland.

This highly diverse facility has pioneered the development of solar energy applications worldwide. The Solar Energy and Energy Conversion Laboratory (SEECL) was unique in developing practical solar energy devices based on established principles of thermodynamics, heat transfer, and fluid mechanics long before solar energy was considered a serious energy alternative.

This was one of the first power facilities to demonstrate the feasibility of long distance electric power transmission. Through an elaborate switchboard at the main station, tied to similar boards at substations, a complete circuit was created to drive an electric motor 153 miles from the generator a remarkable distance at that time.

Three rivers - the Allegheny, Monongahela, and Ohio - join in Pittsburgh, making the city a natural site for the building of bridges. But the Smithfield Street Bridge stands apart from other Pittsburgh bridges for several reasons: it replaced structures by two well-known bridge engineers, Lewis Wernwag and John A. Roebling; it was the first use in America of the lenticular - or lens-shaped - truss design; and it was one of the first major bridges in the U.S. built primarily with steel.

The basic research tool at SLAC is an intense beam of electrons that have been accelerated by an electric field equivalent to 30 billion volts, making this the most powerful electron beam in the world.
The two-mile linear accelerator produces this field using high-power microwaves traveling through an evacuated waveguide. Electrons injected into one end of this pipe are continuously accelerated by this traveling field to very high energies.
