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.

Ship Model, Victory Ship Type VC2-S-AP
- Description
- By 1943, the outlook for an Allied victory in World War II was steadily improving. The reign of the U-boats that had plagued Allied convoys in the Battle of the Atlantic was coming to an end. And the Axis powers were finally losing the tonnage war, which aimed to sink Allied merchant ships faster than replacements could be built. While the mass-produced Liberty ships were faithfully carrying cargo and troops to war zones, these ships were relatively slow. In response, the War Shipping Administration commissioned a new class of emergency vessels called Victory ships. This model represents one of the 534 Victory ships that were built alongside the Liberty ships in seven shipyards around the country.
- Speed was the key difference between the Victory and Liberty ships. When Liberty ships were designed, all of the new steam turbine engines were reserved for naval vessels, leaving the Liberty ships with reciprocating steam engines. While these engines were reliable, the ships could only reach 11 knots, leaving them vulnerable to attack. As the war progressed, more turbine engines became available and were installed in the Victory ships, giving them a speed of over 16 knots.
- Another improvement of the Victory design was a stronger and larger hull. This meant that more cargo could be transported at once, and improved the odds of the vessels continuing to serve in the merchant fleet during times of peace. After World War II, 170 Victory ships were sold as commercial freighters. About 20 were loaned back to the military and used in the Korean and Vietnam Wars. Several Victory ships have been preserved as museum ships and are currently located in California and Florida.

Model, LNG Carrier Methane Shirley Elisabeth
- Description
- Liquid natural gas (LNG) is composed mostly of methane (80–99%). For shipping, it is chilled to -260°F, at which point it is condensed into a liquid 1/600 of its original volume. It is transported globally in this form aboard ships with insulated containers that offload it at special terminals.
- LNG tankers have been around the United States since 1959, when the first cargo was exported from Lake Charles, Louisiana, to England. There are around 200 LNG tankers in service in 2007, and nearly that many more are on order at specialized shipyards to meet the globe’s growing demand for this source of energy.
- LNG tankers have completed more than 40,000 voyages without serious incident; they have the best safety record of any category of commercial shipping. However, they are among the world’s most expensive and difficult ships to build.
- Methane Shirley Elisabeth is one of the newest types of LNG tankers, having been delivered to its owners in March 2007. Its double hulls, separated by six feet of seawater, protect the four gas tanks, which are refrigerated and insulated to maintain the -260°F temperature. The tanks, or membranes, consist of layers of stainless steel and other materials alternating with thick foam insulation. The insides of the membranes are lined with stainless steel, corrugated in two dimensions to prevent the frozen gas from sloshing around inside.

Ship Model, ms Zuiderdam
- Description
- This waterline model represents the ms Zuiderdam, a cruise ship owned and operated by Holland America Line. The Zuiderdam was built in Marghera, Italy, by Fincantieri, a firm specializing in modern cruise ships, and began service in 2002. The ship is the first in Holland America’s Vista-class series, the company’s new line of vessels featuring diesel-electric power plants for energy savings and an Azipod propulsion system for greater maneuverability. All Vista-class vessels are 81,769 gross tons and carry 1,848 passengers with a crew of 800. The Zuiderdam’s home port is Rotterdam.
- Holland America Line designs its ships and markets its cruises for what the industry considers the premium markets. The Zuiderdam features Venetian-themed artwork and offers a variety of suites, staterooms, restaurants, lounges, and cafes, as well as recreational facilities including a theater, a golf simulator room, a casino, and a spa. Like other large cruise ship companies, Holland America caters largely to American customers. It runs vessels in all of the major cruise markets, including the Caribbean, Alaska, Asia, the South Pacific, Europe, and the Mediterranean.
