Studies on the feasibility of building a hydro plant in the site were initiated in 1893. The increasing need for power that was cheaper and easily adapted to mine underground use drove the Lota coal mine company to develop a study of alternatives for this purpose. Engineer William E. Raby traveled to the United States and Europe to assess the use of electricity generation and transmission. The availability of the Chivilingo hydro resources arose as a better alternative to a steam plant.

Smaller and cheaper than a triple-expansion vertical engine, the horizontal cross-compound pumping engine, Pump No. 2, ran at relatively slow revolutions and was considered the height of engineering from the 1890s to World War I. This pumping engine at the York Water Company was built by the Worthington Pump & Machinery Corporation, Snow-Holly Works, Buffalo, New York.

With the discoveries of South Africa's diamonds in the 1860s and gold in the 1880s, immigrants flooded into Cape Town and changed it into a major commercial center. Unfortunately, its water supply had not kept pace with the population growth. After several droughts and years of inadequate water supply, the Woodhead Tunnel was constructed between 1887 and 1891. When it failed to solve the water shortage problem, the Municipality of Cape Town determined that a dam and reservoir needed to be built.

The Williams-Miles History of Chemistry Collection, established in 1992, is one of the leading historical collections of chemistry books in the southern United States. It represents a combined 70 years of scholarly collecting by Wyndham D. Miles, National Institutes of Health, Bethesda, Maryland, and William D. Williams, Professor of Chemistry at Harding University. More than 2,000 volumes published between 1600 and 1900 are preserved here; the collection is particularly strong in 19th-century works.

The structure has two segments: an East Channel bridge consisting of four 175-foot spans and three 240-foot spans crossing from Harrisburg to City Island; and a West Channel bridge, consisting of seven 175-foot spans crossing from City Island to Wormleysburg.
With 15 truss spans totaling 2,820 feet, the Walnut Street Bridge is the finest and largest surviving example of the standardized Phoenix wrought-iron truss bridges produced from 1884 to 1923.

In the early 1900s, Union Station was the hub of passenger railroad traffic in the central United States. It was one of the first stations to serve as a centralized terminal for multiple railroad lines. It originally served 22 rail lines; 13 from the east and nine from the west.

The Turbinia was the world's first turbine-driven ship. It attracted worldwide attention at the 1897 Spithead Naval Review by traveling more than 34 knots. This remarkable performance accelerated the acceptance of the steam turbine as an alternative to the steam reciprocating engine on ships as well as for central electric light and power stations. Sir Charles A. Parsons (1854-1931) invented (1884), developed, and promoted the steam turbine, as well as the design of the Turbinia. For this, he is considered among the outstanding technological innovators of all time.
