Summary:

Science Service was established in 1920 through the efforts of the E. W. Scripps Company in collaboration with the American Association for the Advancement of Science (AAAS), the National Academy of Sciences (NAS), and the National Research Council (NRC). In 1919 Scripps had established the American Society for the Dissemination of Science. Unknown to Scripps, the three major scientific organizations were trying to agree on a format and establish a popular science journal. In 1920 Scripps met with representatives of the AAAS, NAS, and NRC in an attempt to pool resources. Out of that meeting came Science Service, a news service designed to popularize science and to disseminate scientific knowledge. This accession consists of Science Service files that were given to and maintained by the Division of Electricity and Modern Physics (E&MP), National Museum of American History (NMAH), which later became part of the Division of Information Technology and Society and then Division of Work and Industry after that. The files in this collection relate specifically to the subject of electricity. Also covered and related to the subject area of electricity are automobiles, batteries, camera, communications, electric circuits, electric generators, lighting, electric machinery, electric power plants, electric power transmission, electrical engineering, electromagnets, electron microscope, fuel cells, integrated circuits, lasers, phonographs, radio, radio transmission, telephones, and television. Materials include correspondence and memoranda, photographs, news releases, and clippings. Some subjects are listed but the envelopes are missing. A select number of images were digitized and appeared on a Science Service website created and maintained by Nance L. Briscoe, Collections Manager, and later by Harold D. Wallace, Curator, Division of Work and Industry, NMAH. The site has been taken down by NMAH but can still be accessed through Accession 14-071: National Museum of American History, Website Records, 2008-2013, Smithsonian Institution Archives.

E&MP 1.015 (CD2055001): Voltswagon - Electric truck is ahead of the electric passenger car in its development and use. Made by the Battronic Truck Corporation, Philadelphia, this truck is already in use by dairies and laundries in the Philadelphia area. Similar trucks compete satisfactorily with traffic in many English and Canadian cities, but are being equipped with American-designed bodies. December 29, 1965.

E&MP 1.016 (CD2055002): Electric truck - A new electric is expected on the market soon, and a little imagination can picture the completed job, including a housewife in an advertisement to show how any family can have a "second" car for less than $1,000. This one is expected to run 35 miles an hour, ideal for suburban driving. Not least in its assets is the lessening of air pollution. December 12, 1965.

E&MP 1.017 (CD2055003): Electric truck - Sodium-Sulfur Battery. Ford Motor Company has demonstrated a major breakthrough in its efforts to develop a feasible power source for electric vehicles. Developed by Drs. Neil Weber (left) and Joseph T. Kummer, shown with an operating cell and a model of a 2,000 watt unit, the new sodium-sulfur battery system should be able to store up to fifteen times the amount of electrical energy available from present lead-acid storage batteries. The heart of the new system is a Ford-developed crystalline ceramic electrolyte composed largely of aluminum oxide and based on a material known as beta-alumina. Further development of the Ford battery should lead to an economical, rechargeable battery system which, when adapted to a vehicle would provide greatly improved acceleration and range capabilities than now available from existing batteries. October 31, 1966. (Original caption by Science Service, Copyright - Ford Motor Company)

E&MP 1.022 (CD2055008): Fold Developed Solid Electrolyte, 1967. Ford Motor Company has demonstrated a major breakthrough in its efforts to develop a feasible power source for electric vehicles. The heart of the new sodium-sulfur battery system is a Ford-developed crystalline ceramic electrolyte composed largely of aluminum oxide and based on a material known as beta-alumina. This material selectively passes sodium ions while containing all other liquids, including liquid sodium and liquid sulfur. The ceramic can be formed and sintered by commercially feasible techniques and its conductivity at operating temperatures - 250 to 300 degrees centigrade - compares favorably with electrolytes used in conventional battery systems such as sulfuric acid and potassium hydroxide.

E&MP 1.024 (CD2055010): Ford Electric City Car Concept, 1967. As part of an overall program to develop feasible power sources, motors and controls for electric vehicles, Ford Motor Company and Ford of Britain are engineering jointly a low-cost, sub-compact, limited performance City-Car, to carry two adult passengers and two children. Designed for operation either in crowded cities such as London or for running errands in residential and suburban areas, the car will be powered initially by lead-acid batteries. With advanced components, the car will have a range of up to 150 miles -- at a continuous speed of 40 miles an hour. Build on the first prototype is under way and is expected to be completed in the spring of 1967. A second car also will be produced in England for testing and evaluation in urban-suburban application in the United States. (Original caption by Science Service, Copyright - Ford Motor Company)

E&MP 1.035: Electric Urbmobiles, July 16, 1966. Artist's sketch shows electric Urbmobiles traveling at 60 mph on automated tracked guideway for travel to and from suburbs, with power coming from third, electrified rail. For travel on existing street network the fume-free Urbmobile would be driven manually and powered by electric storage batteries. Cornell Aeronautical Laboratory has recently completed a year-long $110,000 feasibility study of such a future transportation system for the U.S. Department of Housing and Urban Development. HUD considers the concept of a small dual-mode electric car to be a promising idea which should be investigated further. The Urbmobile system was conceived in answer to a need for reducing air pollution, sluggish traffic movement and excessive land requirements for streets and parking areas.

Subject 2 - Automobile Safety

E&MP 2.001: Guillotine Look-Alike Safety Tool, November 16, 1967. A device resembling the notorious guillotine has found its place as a safety tool at the General Motors Proving Ground near Milford, Mich. This impact device drops an instrumented load cell on the chests of test dummies to calibrate - or standardize - the spring rate of the dummies' chests. These dummies are used to test the performance of production and experimental steering assembly designs on a special test fixture which slams the dummy against the wheel. The impact device has been used by GM Proving Ground engineers to calibrate chest spring rates on all dummies used by the entire automotive industry for testing compliance with Federal Motor Vehicle Safety Standards. By using only one device, engineers make sure that wherever the dummies are used test results can be compared accurately. Several supplier and accessory firms also have had dummies calibrated on the Proving Ground equipment. (Original caption by Science Service, Copyright - General Motors)
