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.

Description (Brief)
Solar cells come in many shapes and sizes, and are manufactured with a variety of materials. The wafer of this octagonal cell is made with the element silicon. The dark areas convert sunlight into electricity while the thick and thin lines are part of the electrical circuit. This “wraparound-contact” cell has two thin parallel circuit-leads running from top to bottom and about 100 smaller leads running crosswise. Each of the four corners has seven lines running crosswise, making a connection to the back of the wafer.
