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.

Plate 33. Evacuation of Aquia Creek
- 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 sketch was taken a few hours previous to the abandonment of Aquia Creek in June, 1863. The Army of the Potomac was along the Rappahannock before Fredericksburg, fifteen miles distant, and had used this point and Belle Plain, a similar landing, seven miles below, as a base of supplies. The movement commenced on Saturday morning. The President was expected to visited the army on that day, but the advance of the Confederates into Pennsylvania admitting of no delay, Gen. Hooker, in the afternoon, telegraphed Mr. Lincoln not to come, and immediately made preparations to leave. At daylight, Sunday morning, the whole army was in motion, and an immense throng of sutlers and other camp followers collected at Aquia Creek for transportation to Washington. By 10 A. M. the camps between this point and Fredericksburg were all deserted, and the civilians, in constant apprehension of an attack from the Confederate cavalry that might follow up the army as it passed the landing on its march to Washington, crowded on to the boats in the greatest confusion. The steamers were already heavily laden with stores, wagons, &c,, and the evacuation was attended with scenes that would have been regarded as ridiculous but for the general alarm.
- The barges anchored in the stream were locked together for the transportation of the cars on the wharf, and were towed to Washington by the steamers loaded with passengers. All of the supplies had been removed from the buildings, and the latter, erected at great expense by the Quartermaster's Department, were committed to the flames. A gunboat lay out in the river for the protection of the place until all could get away; but no enemy appeared, and in a short time nothing remained of the busy village but smoking embers and half-burned wharves. Aquia Creek has been used three times as a base of supplies; once for McDowell, in 1862; next for Burnside, after the Antietam Campaign; and finally during Grant's operations at Spottsylvania. Nearly a hundred steamers have been collected here at one time, while sailing vessels anchored in the river nearly obstructed its navigation. The wounded were brought here from Fredericksburg, Chancellorsville, Wilderness, and Spottsylvania, to be sent to Washington; and in nearly all of the operations of the army in Eastern Virginia the place has borne a conspicuous part. The Confederates had formidable batteries on the bluffs which commanded the river previous to our occupation of Fredericksburg in the spring of 1862, and at the same time sheltered in the stream that runs down between the hills, the once notorious iron-clad Page.
- The landing is now used by the Washington, Fredericksburg and Richmond Railroad Company, but will probably never be more than an ordinary station. Fever and ague prevail during the summer, forbidding the growth of a village, and with the completion of the railroad to Alexandria, the place will doubtless sink into oblivion, except as connected with the military operations of the great rebellion.

Old Glory flag
- Description
- The name "Old Glory" was loudly proclaimed in 1824 by Captain William Driver as he hoisted the flag given to him as a birthday present. The flag would accompany Driver on his numerous voyages around the world. When he gave up seafaring and moved inland to Nashville, Tennessee in 1837, Driver continued to display the flag proudly by hanging it from a locust tree. He even updated the flag in 1861 to reflect thirty-four stars and added an anchor in the corner to indicate his sea service. When Tennessee seceded from the Union, Driver had the foresight to hide the flag and had his daughter conceal it inside a quilt, which was overlooked in numerous raids on his house. Old Glory remained in the quilt until February 25, 1862 when Ulysses S. Grant captured Fort Donelson and occupied Nashville. On that day Driver uncovered the flag, marched through the streets to the capitol building, climbed to its dome, and hoisted the flag for all to see.

Plate 94. A Burial Party on the Battle-field of Cold Harbor
- Description
- Text and photograph from Gardner's Photographic Sketchbook of the War, Vol. II. Negative by John Reekie, text and positive by Alexander Gardner.
- This sad scene represents the soldiers in the act of collecting the remains of their comrades, killed at the battles of Gaines' Mill and Cold Harbor. It speaks ill of the residents of that part of Virginia, that they allowed even the remains of those they considered enemies, to decay unnoticed where they fell. The soldiers, to whom commonly falls the task of burying the dead, may possibly have been called away before the task was completed. At such times the native dwellers of the neighborhood would usually come forward and provide sepulture for such as had been left uncovered. Cold Harbor, however, was not the only place were [sic] Union men were left unburied. It was so upon the field of the first Bull Run battle, where the rebel army was encamped for six months afterwards. Perhaps like the people of Gettysburg, they wanted to know first "who was to pay them for it." After that battle, the soldiers hastened in pursuit of the retiring columns of Lee, leaving a large number of the dead unburied. The Gettysburgers were loud in their complaints, and indignantly made the above quoted inquiry as to the remuneration, upon being told they must finish the burial rites themselves.
- Among the unburied on the Bull Run field, a singular discovery was made, which might have led to the identification of the remains of a soldier. An orderly turning over a skull upon the ground, heard something within it rattle, and searching for the supposed bullet, found a glass eye.

Plate 59. Battery A, Fourth U.S. Artillery, Robertson's Brigade
- Description
- Text and photograph from Gardner's Photographic Sketchbook of the War, Vol. II. Negative by James Gardner, text and positive by Alexander Gardner.
- This is one of the celebrated horse batteries of the Army of the Potomac. In the batteries designed for cavalry service, every man was mounted, except in action, when the cannoniers necessarily served the guns on foot. The picture represents the four 12-pounder light brass pieces "in battery," with limbers and caissons to the rear, and on the left the battery wagon, forge, ambulance, and wagons for transportation, embracing the entire equipage of a light battery in the field. Beyond, another battery is seen in camp. The horses being hitched in, and limber chests open, would seem to indicate that an inspection is about to be made. Just in the edge of the woods is brigade headquarters.
- When General Pleasanton commanded the cavalry of the Army of the Potomac, in 1862, Captain Robertson (now General) was his Chief of Artillery, and was in the van of the forces, in the campaign which terminated at Antietam. The Captain aided materially in driving the rebels out of Frederick City, after a severe artillery fight. Following them closely, he fired the first shot at the battle of South Mountain, keeping the rebels engaged till the arrival of General Burnside's command. Again, at the battle of Antietam, his batteries were busy doing great execution. He was promoted subsequently, and held a command in the reserve artillery, for some time, always with the reputation of being a thorough artillery officer.
