Energy & Power
The Museum's collections on energy and power illuminate the role of fire, steam, wind, water, electricity, and the atom in the nation's history. The artifacts include wood-burning stoves, water turbines, and windmills, as well as steam, gas, and diesel engines. Oil-exploration and coal-mining equipment form part of these collections, along with a computer that controlled a power plant and even bubble chambers—a tool of physicists to study protons, electrons, and other charged particles.
A special strength of the collections lies in objects related to the history of electrical power, including generators, batteries, cables, transformers, and early photovoltaic cells. A group of Thomas Edison's earliest light bulbs are a precious treasure. Hundreds of other objects represent the innumerable uses of electricity, from streetlights and railway signals to microwave ovens and satellite equipment.

H. M. Wood Windmill Patent Model
- Description
- During most of the 19th century, the U.S. Patent Office required inventors seeking patent protection to submit both a written application and a three-dimensional model. This wood and metal patent model of a windmill succeeded in gaining its inventor, H. M. Wood, Patent Number 222,340, which was issued on December 2, 1879. As farms spread into the American heartland, windmills proved an extremely important technology, allowing settlers to use the renewable power of wind to pump groundwater for agricultural and household use. Efficiency and reliability were key attributes for rural windmills, and professional and lay inventors experimented with hundreds of design variations throughout the years.

Model of Bucyrus-Erie Stripping Shovel
- Description
- In 1960, the Bucyrus-Erie Company of South Milwaukee, Wisconsin, presented this 14-inch-high, scale model of what was to become the world's largest stripping shovel to President Dwight D. Eisenhower. Later that year, the President transferred this gift to the Smithsonian Institution. The Bucyrus-Erie Company had custom-designed this monster machine for the Peabody Coal Company. Bucyrus-Erie engineers anticipated that they would need two years to manufacture the behemoth, and an additional six months to assemble it at the site of the open-pit mine. (They planned to ship the machine's parts in over 250 railcars.) When finished, the shovel would weigh 7,000 tons, soar to the roofline of a 20-story building (some 220 feet high), and be able to extend its enormous 115-cubic-yard dipper over 460 feet, or about the length of an average city block. (The dipper's capacity would equal that of about six stand-sized dump trucks.) Fifty electric motors-ranging from 1/4 to 3,000 horsepower-would power the shovel, which was designed to be controlled by a single operator, perched in a cab five stories high. Publicists for Bucyrus-Erie called this the "largest self-powered mobile land vehicle ever built."

Carrier Centrifugal Refrigeration Compressor
- Description
- The first successful mechanical refrigeration equipment was patented soon after the Civil War, but the large size and high cost of these early machines restricted their use to industrial processes. In his effort to improve mechanical air-conditioning systems, Willis Haviland Carrier (1876-1950) introduced the first practical centrifugal refrigeration compressor in 1922 (pictured here). This machine provided the foundation for safer, smaller, and more powerful and efficient large-scale air-conditioning systems.
- Prior to the introduction of the centrifugal compressor--which compressed the refrigerant gas through the centrifugal force created by rotors spinning at high speed—reciprocating compressors compressed the refrigerant by the action of pistons inside cylinders, much like an automobile engine. The centrifugal compressor proved an extremely important advancement and paved the way for "comfort" air conditioning in theaters, department stores, hospitals, banks, offices, and hotels.
- Carrier installed this initial compressor at his company's Newark, N.J., offices, where he gave the first public demonstration of the machine on May 22, 1922. Two years later, he sold the compressor to the Onondaga Pottery Company of Syracuse, N.Y., for the air conditioning of its lithography plant. The machine remained in use there until about 1957, when the Carrier Company repurchased the compressor for donation to the Smithsonian. Earlier, in 1924, the Carrier Company had installed centrifugal refrigeration machines in the J. L. Hudson department store in Detroit and the Palace Theater in Dallas, thereby introducing the phrase "air conditioning" into the public vocabulary.

Niagara Falls Original Turbines
- Description
- Using this extremely fine wood model as part of its technical proposal, the Swiss firm Faesch & Piccard won the contract to design the original turbines for the Niagara Falls power station. The actual turbines were built by the I. P. Morris Company of Philadelphia and were installed in 1895, the year the Adams Station went on line. The hydroelectric power generation facility at Niagara Falls gained international acclaim for its ability to efficiently convert a portion of the Falls' awe-inspiring natural energy into electricity. This was the world's first large-scale central electric power station, demonstrating how falling water (or other power sources) could be used successfully to supply electricity over an extended geographical area.

Electrically Welded Specimen, Bicycle Top Tubing
- Description
- This bicycle’s welded steel top tube was created using Elihu Thomson’s electric welding apparatus (see object number MC*181724). Welding samples demonstrated potential industrial applications of electric welding, and illustrations of these samples were published in journals, brochures, and advertisements. Elihu Thomson’s invention of electric welding in 1885 resulted in numerous applications including the manufacture of automobile parts, tools, screws, ball bearings, and wire lines. Thomson’s welding apparatus passed an electric current through two pieces of metal pressed together. Resistance to the current at the contact point between the metal pieces created heat and welded the metals together.
- Scientist and inventor Elihu Thomson (1853-1937) played a prominent role in the industrialization and electrification of America with over 700 patents in his name. His inventions and patents helped change the nature of industry in the United States and included the “uniflow” steam engine, automobile muffler, producing fused quartz, stereoscopic x-ray pictures, electric arc lamps, lightning arrestors, and perhaps most notably—the process of electrical welding. Thomson and partner Edwin Houston established the Thomson-Houston Electric Company in 1883. In 1892 Thomson-Houston merged with the Edison Electric Company to form General Electric.

Electric Power Transmission Cable
- Description (Brief)
- The cables needed to transmit electrical power may seem simple but are actually complex technological artifacts. Modern cables inherit the lessons learned during more than a century of research and experience. This power cable was described by GE engineer William Clark in 1898 as follows: “1,000,000 [circular mil] cable composed of 59 wires, each .1305" in diameter, containing two insulated pressure wires each 2500 C.M. area, the whole insulated with saturated paper 5/32" thick and finished with lead 1/8" thick. This is a feeder cable for circuits not exceeding 2000 volts working pressure on Edison three wire circuits."
