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.

This object may be the first laser. It was made by Theodore Maiman and his assistant Irnee D'Haenens at Hughes Aircraft Company in May 1960.In 1959 Maiman attended a technical conference on the subject of lasers.
Description
This object may be the first laser. It was made by Theodore Maiman and his assistant Irnee D'Haenens at Hughes Aircraft Company in May 1960.
In 1959 Maiman attended a technical conference on the subject of lasers. Maiman heard several speakers state that ruby was unsuitable for a laser but grew troubled by some of the numbers they cited. When he returned to his lab at Hughes he began experimenting. By May 1960 he and D'Haenens constructed several small metal cylinders. Each contained a photographer's spiral-shaped, xenon flashlamp that surrounded a small cylindrical crystal of synthetic ruby. When they fired the flashlamp, the burst of light stimulated the ruby crystal to emit a tightly focused pulse of light--the first operating laser.
Hughes Aircraft donated this and several other pieces of Maiman's apparatus to the Smithsonian in 1970. The crystal mounted inside this unit is from a 1961 experiment. While the donation records indicate that this is the first laser, Maiman wrote that he received the first laser as a gift when he left the company in April 1961. Several experimental models were made during the research, a common practice. So we may never know which unit actually generated the first laser light.

This is an experimental ruby laser made in 1963 at Ohio State University.
Description
This is an experimental ruby laser made in 1963 at Ohio State University. Edward Damon, a researcher at the University’s Antenna Laboratory, made this and several other lasers during his investigation of Theodore Maiman’s ruby laser experiments of three years earlier.
In addition to replicating Maiman's 1960 experiments, Damon wished to explore variations of the ruby laser. Unlike Maiman's laser, this laser does not use a spiral flashlamp to energize the ruby crystal. Instead, Damon placed three linear flashlamps parallel to the rod-shaped laser crystal. Firing these lamps simultaneously provided energy to the crystal. The laser also demonstrates a water cooling technique still used in some lasers today.

This is an experimental device made by Theodore Maiman at Hughes Aircraft in late 1959 or early 1960 as part of the series of experiments leading up to the demonstration of the first laser in May 1960.
Description
This is an experimental device made by Theodore Maiman at Hughes Aircraft in late 1959 or early 1960 as part of the series of experiments leading up to the demonstration of the first laser in May 1960. This object features a cube-shaped ruby crystal mounted at one end of a microwave wave-guide. Maiman sought to test the response of the synthetic ruby crystal to microwave stimulation. Other researchers claimed that ruby would be a poor material to use in a laser. Maiman thought otherwise.
After Charles Townes invented the microwave-emitting maser in 1954, researchers began trying to move to the higher energy levels of infrared and visible light. They referred to such devices as "optical masers," and only later did people adopt Gordon Gould's term, "laser." This experimental piece clearly shows the influence of microwave technology. The metal tube is not a stand but rather a hollow guide that channels microwaves to the ruby crystal. The results of this and other experiments led Maiman to ultimately choose a cylinder of ruby rather than a cube for his laser.

Scotsman Alexander McDougall (1845-1924) was a ship captain on the Great Lakes when he patented the idea of a “whaleback” ship in the early 1880s. With low, rounded hulls, decks and deckhouses, his invention minimized water and wind resistance.
Description
Scotsman Alexander McDougall (1845-1924) was a ship captain on the Great Lakes when he patented the idea of a “whaleback” ship in the early 1880s. With low, rounded hulls, decks and deckhouses, his invention minimized water and wind resistance. Between 1887 and 1898, 44 whalebacks were produced: 23 were barges and 21 were steamships, including one passenger vessel.
Frank Rockefeller was the 36th example of the type, built in 1896 at a cost of $181,573.38 at McDougall’s American Steel Barge Company in Superior, WI. One of the larger examples of the type, Rockefeller measured 380 feet in length, drew 26 feet of water depth and had a single propeller.
Although it belonged to several different owners over its 73-year working life, the Rockefeller spent most of its early life transporting iron ore from mines in Lake Superior to steel mills along the shores of Lake Erie. In 1927, new owners put it in service as a sand dredge that hauled landfill sand for the 1933 Chicago World’s Fair. From 1936-1942 the old ship saw service as a car carrier for another set of owners. In 1942 the ship wrecked in Lake Michigan, but wartime demand for shipping gave the old ship repairs, a new name (Meteor) and a new life as a tanker transporting petroleum products for more than 25 years. In 1969 Meteor ran aground off the Michigan coast, Instead of repairing the old ship, the owners sold it for a museum ship at Superior, WI. In poor condition today, Meteor is the last surviving example of McDougal’s whaleback or “pig boat”.

The term “home-made laser” almost seems a contradiction but that is not the case. This gas laser was built by high school student Stephen M. Fry in 1964, only four years after Ali Javan made the first gas laser at Bell Labs.
Description
The term “home-made laser” almost seems a contradiction but that is not the case. This gas laser was built by high school student Stephen M. Fry in 1964, only four years after Ali Javan made the first gas laser at Bell Labs. Fry followed plans published in Scientific American's "The Amateur Scientist" column in September 1964, (page 227).
The glass tube is filled with helium and neon and, as the magazine reported, "seems to consist merely of a gas-discharge tube that looks much like the letter 'I' in a neon sign; at the ends of the tube are flat windows that face a pair of small mirrors. Yet when power is applied, the device emits as many as six separate beams of intense light."
The discharge tube is the only piece of this particular laser that remains. The flat windows (called "Brewster windows") are square instead of round, and the electrodes are parallel to the gas tube instead of perpendicular. Otherwise it resembles the drawings in the magazine. Fry later earned a Ph.D. in physics with a dissertation on lasers.
