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.

Mailbox
- Description
- Thousands of homes were obliterated by the effects of Hurricane Katrina in August 2005. One of those homes stood at 2005 Lizardi Street in the Lower Ninth Ward of New Orleans. This mailbox is all that remained, except for the front steps and a field of debris.
- The hand-painted green flowers and butterflies on this mailbox, and the carefully lettered name and address of the Alexander family, evoke the domestic serenity that was shattered by Katrina's waters. Inside the mailbox a thick layer of dried mud recalled the wall of water that washed over this neighborhood August 29, 2005, when everything in its path was either submerged or destroyed.
- The Lower Ninth Ward was a victim of the over-burdened Industrial Canal, whose concrete flood walls collapsed beneath the weight and force of the water. Further afield, a manmade navigation canal, the Mississippi River Gulf Outlet ("Mr. Go"), offered a short cut not only to ships leaving the Gulf headed for New Orleans but for storm water moving inland from the Gulf. It was this water that in large part flooded the Industrial Canal and devastated the Lower Ninth Ward.

Lewis Latimer Patent Drawing
- Description
- Electricity pioneer Lewis Latimer drew this component of an arc lamp, an early type of electric light, for the U.S. Electric Lighting Company in 1880.
- The son of escaped slaves and a Civil War veteran at age sixteen, Latimer trained himself as a draftsman. His technical and artistic skills earned him jobs with Alexander Graham Bell and Thomas Edison, among others. An inventor in his own right, Latimer received numerous patents and was a renowned industry expert on incandescent lighting.

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."

Plate 68. Charles City Court-House, Virginia
- Description
- Text and photograph from Gardner's Photographic Sketchbook of the War, Vol. II. Negative by Timothy H. O'Sullivan, text and positive by Alexander Gardner.
- This place is the county seat of Charles City County, about twenty-five miles southeast from Richmond, and is a fair specimen of many Virginia Court-Houses. This neighborhood was the scene of a number of severe cavalry fights during the war, the Court-House, in 1862, being only three miles from the intrenched camp of Gen. McClellan, whose army marched past the village in its retreat from before Richmond to Fortress Monroe. Gen. Meade's army, in 1864, again occupied this section, and passed over its roads from Coal Harbor to Petersburg, when the building was sacked by the troops, and many of the records were destroyed. There were but two or three dwellings and a church composing the village, and a stranger might pass through the place without dreaming that it possessed a name. Its history dates from the early settlement of Virginia, and the cemeteries round about it contain the names of those who passed away one hundred years ago.
- The return of peace has here failed to quicken the people, and everything is rapidly sinking to decay. The aristocratic families, impoverished by the war, and deprived of the labor of their slaves, barely manage to live, and the whole country along the James is rapidly becoming overgrown with scrub timber and chaparral.

Plate 99. McLean's House, Appomattox Court-House, Where Grant and Lee signed the Capitulation
- Description
- Text and photograph from Gardner's Photographic Sketchbook of the War, Vol. II. Negative by Timothy H. O'Sullivan, text and positive by Alexander Gardner.
- On the evening of the 7th of April, 1865, General Grant first forwarded, under a flag of truce, a letter to Gen. Lee, demanding the surrender of the Army of Northern Virginia, in order to avoid the further effusion of blood. That army had re-crossed the Appomattox river at High Bridge and Farmville, closely pressed by Sheridan's cavalry and the Armies of the Potomac and James. On the 8th, some correspondence passed between the two Commanding Generals, the one army retreating towards Lynchburg, followed by the Second and Sixth Corps, whilst the cavalry and the Fifth and Twenty-Fourth Corps made forced marches in order to pass around and gain the front of the enemy. About noon on the 9th, the head of the Second Corps, when within three miles of Appomattox Court-House, came up with the rear guard of the enemy; and at the same time, Gen. Lee, in person, appeared with a flag of truce, and, by letter, asked for a suspension of hostilities, pending negotiations for a surrender. About four o'clock in the afternoon of that eventful Sunday, the glad tidings was announced throughout the Union Armies that the Army of Northern Virginia had surrendered. The excitement among our troops was unparalleled, officers and men uniting in the most extravagant demonstrations of joy. The photograph represents the house in which the terms of capitulation between Generals Grant and Lee were signed. The apple tree (about half a mile from the Court-House) under which they first met, has been entirely carried away in pieces, as mementoes, not even the roots remaining.
- It is a singular fact that the owner of this house, Mr. McLean, was living on the first Bull Run battle-field at the time of that engagement, and afterwards removed to this place for the purpose of being secure from the visitation of an army.

Plate 90. Old Capitol Prison, Washington
- Description
- Text and photograph from Gardner's Photographic Sketchbook of the War, Vol. II. Negative by William R. Pywell, text and positive by Alexander Gardner.
- The Old Capitol Prison, previous to the war, was a dingy, crumbling structure, with rambling passages, and with quaint rooms where one least expected to find them. The staircases ran up about the building with a sort of uncertainty that bewildered the visitor, and dust and cob-webs hung upon its walls so thick, that one walked cautiously along its floors, lest a heavy tread should bring down the accumulated filth of years upon his head. Congress ordered its erection during the war of 1812, for its own use until the Capitol, burned by the British, could be rebuilt; and after the completion of the latter, this establishment was used as a boarding house for members. The lower part of the city becoming the centre of business, the Old Capitol was abandoned by its lodgers, and rapidly sunk to decay; some of the lower class occasionally renting apartments, but never remaining any length of time. At the commencement of the war, its only tenant was an humble German, who managed to subsist himself and family, as a cobbler, and who was not at all displeased at the sudden termination of his lease by the military authorities. Iron bars were placed in the windows, the doors of the several apartments were strengthened, and the building soon became notorious as a prison for military offenders, prisoners of state and captured rebels. Many prominent Confederate Generals have been confined in it, and scores of citizens engaged in disloyal practices, suddenly found their plans frustrated, and themselves on their way to its cells before they could give a word of warning to associates. Captain Wirz, the Andersonville prison-keeper, was imprisoned here, and expiated his crimes upon the gallows in its yard, as had numbers of offenders before him.
- When occupied by prisoners, its windows were generally crowded by its inmates, and passers by were not allowed to stop at any time on the opposite side of the street, lest they should attempt to communicate, by signs, with those within the prison. The regulations required that all correspondence and reading matter, as well as food for the prisoners should be closely scrutinized, so as to prevent any improper communication or aid from the outside. Among the plans for conveying money and messages from external sources, was that of secreting in packages of smoking tobacco the object to be transmitted. This, however, was early detected, and afterwards was never attempted with success. Underscoring words in books, at long intervals, so that when taken together they would embody a sentence, was not unusual with the prisoners when about to return to their friends volumes that had been loaned them for perusal. The latter occasioned considerable labor to the officers of the prison, every book going to or from the inmates being carefully examined, not only for messages of this kind, but for communications that might be concealed between leaves pasted together. The prisoners attempted to tunnel out several times, but never with success. A few escaped from the windows, but most of them who undertook it were discovered and recaptured. One young man fixed a spring-board in an upper window, and attempted to jump out into the street, but broke his leg, and by his signal failure discouraged any other efforts to escape in this manner. A strong guard was always kept in the passages of the prison as well as on the streets surrounding it, and during the last two years of the war, none ever succeeded in eluding the vigilance of their keepers.

Cladding Fragment from the World Trade Center
- Description
- Description: This crumpled piece of exterior sheathing from the World Trade Center was recovered from the debris pile.
- Context: The twin towers of the World Trade Center, a New York City landmark and the tallest buildings in the world when completed in 1973, were noted for their incredible 110-story height and their gleaming exterior. The towers were clad in an aluminum alloy sheathing that gave the buildings a golden sheen at sunrise and sunset. The material covered the closely-spaced exterior steel columns, enhancing their soaring appearance.

Plate 3. Fairfax Court House
- Description
- Text and photograph from Gardner's Photographic Sketchbook of the War, Vol. II. Negative by Timothy H. O'Sullivan, text and positive by Alexander Gardner.
- The Village of Fairfax Court-House, Virginia, eighteen miles from Washington, was, previous to the rebellion, one of the loveliest of the State. Numbering about three thousand inhabitants, with three large hotels, two fine churches, and a flourishing female institute, the place had become of considerable importance at the time of secession, from which it was the first to suffer. Each of the many commands which occupied the town during the war added to the work of devastation commenced in 1861, and long before peace was announced its comeliness had departed. Its best houses were burned, the churches were converted into hospitals, and then into stables, while the venerable Court-House was stripped of its wood-work, leaving only the naked walls and roof. In 1864, loop-holes were cut through the sides of the building for riflemen and troops stationed in it to repel any attack that might be made by guerillas who constantly hovered in the vicinity. The records kept here were of great historical interest, dating from the early settlement of Virginia, and including many documents in the writing of General Washington. A great number of these were carried off by curiosity hunters in the sacking which took place in September, 1862, and a still greater number were ruthlessly destroyed by the soldiery. Generals McClellan and Hooker each temporarily had their headquarters here when in command of the Army of the Potomac, as did also the lamented Sumner, and other officers of equal rank. The battle-field of Bull Run is ten miles distant, and Chantilly, where the gallant Kearney and Stephens fell, but five miles away.
- The village is now, however, rapidly recovering from its misfortunes. Shattered houses have been repaired, families are returning to their homes, the Court-House is being put in order for the occupation of the courts, and, under the influence of Northern enterprise, the town promises soon to wear even more beauty than it ever knew before.

Morse-Vail Telegraph Key
- Description
- Alfred Vail made this key, believed to be from the first Baltimore-Washington telegraph line, as an improvement on Samuel Morse's original transmitter. Vail helped Morse develop a practical system for sending and receiving coded electrical signals over a wire, which was successfully demonstrated in 1844.
- Morse's telegraph marked the arrival of instant long-distance communication in America. The revolutionary technology excited the public imagination, inspiring predictions that the telegraph would bring about economic prosperity, national unity, and even world peace.

Plate 89. Libby Prison, Richmond
- Description
- Text and photograph from Gardner's Photographic Sketchbook of the War, Vol. II. Negative by Alexander Gardner, text and positive by Alexander Gardner.
- The Old Tobacco Warehouse is too well known to need much description. This view was taken after the time was passed when Union officers and men looked wearily through the tiara at the monotonous flow of the James, and wondered how much longer they could endure without going mad; or peeping out into the street at the risk of being fired at by some sentry, watched the relief on its rounds, or the arrival of more prisoners to swell the already overcrowded numbers in durance. The Union flag floats upon the building, and the tables are turned. Rebel prisoners occupy the floors, so lately filled by Northern soldiers, with permission to kick up their heels to their hearts' content. There is a little crowd around the door at the corner, formed of destitute persona seeking relief. It was in this office the Union prisoners were received by the prison-keepers, and coolly dispoiled of any little trifles left about their persona, by their captors. The lower windows on the end of the building, light some of the small cells in the foundation, where officers were placed for punishment. It was here that Captains Flynn and Sawyer were confined, pending the retaliatory execution, to which they were condemned by the rebel authorities, and fortunately prevented by the prompt measures adopted by our Government. When Turner – brother of the notorious Dick – gave himself up, to escape vengeance at the hands of the soldiers, he was deposited in one of these places, that he might have a chance to appreciate the misery of some of those he had so ruthlessly confined there. This view of the Libby is taken from Castle Thunder, a warehouse of the same order of architecture.

Levee Wall Fragment
- Description
- One of the signature events of Hurricane Katrina in August 2005 was the failure of the levees of New Orleans. Seemingly impregnable earthen walls surmounted by concrete barricades turned out to be no match for the surging flood waters that turned Lake Pontchartrain into a force that devastated one of the nation's major cities.
- From the earliest years of the city's establishment several feet below sea level, New Orleans has been at risk of catastrophic flooding. And yet the city's vital location at the mouth of the Mississippi River, taking in raw materials and finished goods and distributing them to the world, was too strong an economic force to be turned away. The threat of water inundation was nothing that good engineering and a few pumps could not overcome.
- But some of the largest drainage pumps in the world were rendered useless on the morning of August 30th when some eighty percent of New Orleans became a part of Lake Pontchartrain. The great pump houses stood silent beneath many feet of flood water. The city that depended upon strong walls and the pumps behind them in order to stay dry had encountered a force of nature unlike anything it had experienced before: a large, strong hurricane sweeping vast quantities of ocean water into the lake at high tide.
- Geological studies would later reveal that some of the earthen levees of New Orleans had been built on soft, peaty soils and that many of the concrete flood walls that topped the levees were poorly anchored. Several of these levees and their walls were undercut and then destroyed by the ponderous weight and power of the lake water.
- To acknowledge the key role of the levees and walls in the flooding of New Orleans by Hurricane Katrina, the Smithsonian selected several decorative chunks of concrete from the damaged floodwall along the London Avenue Canal at Mirabeau Street.
- This floodwall's attractive concrete ribbing faced houses that stood within several feet of the canal, houses later destroyed by waters the levee intended to keep at bay.
