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.

Heanysintered tungsten lamp, c1908. This tungsten lamp was at the heart of a Patent Office scandal that saw two men jailed and Heany’s patents disallowed. See Arthur Bright "The Electric Lamp Industry," for the Heany patent fraud case. There are also contemporary articles in Electrical World.
Brass medium-screw base with skirt, one glass insulator and one ceramic insulator. Seven single-arch non-ductile (sintered) tungsten filaments in series, 7 upper & 6 lower supports (note eyes on upper supports - insulators?), carbon-paste connectors, Siemens seal, asbestos(?) insulator. Tipped S-shaped envelope with taper at neck, 1/2 frost. Mazda A type. “Pat Oct. 15, 1907” stamped on base, “329458”(?) printed on base. “9” inked on one side of press, “H” molded on other side. Label reads: “Heany V Tungsten Pat Dec. 25. 06 Pat Dec. 03. 07 Other Patents Pending”. “Heany” on label in stem. Partial “H” on envelope appears to be remnant of a William Hammer Collection marking.
