Electricity in the Motor Car
By G. Russell Fessenden
WOULD you like to "see" the electricity that puts the life into your motor car, to look into the steel walls of the cylinders and "see" the stream of electrons or whatever it is that causes all the disturbance that makes the wheels go around? Or watch the "juice" kick the lifeless motor and the cold wet gasoline into roaring work and blistering heat as you unleash the starter? Or to peer into the battery and see slabs of lead eaten away to liven up your bus?
All this and more can be brought to the eye through the magic of the screen.
"ELECTRICITY IN THE MOTOR CAR" is the title -of the series of films which have recently been released for explaining the part that electricity plays in the automotive vehicle. The unique feature about these films is that they make extensive use of animated drawings and diagrams to illustrate what actually goes on inside the electrical equipment, and so make the operating principles readily understandable.
SECTIONALIZED VIEW SHOWING INTERIOR OF GENERATOR
This series is put out in 6 reel length for non-theatrical use and in 2 reel length for theatrical. The non-theatrical version is divided into four subjects arranged for showing either at separate times or consecutively, no subject comprising more than two reels.
The theatrical version is arranged as two 1 reel subjects that can be
HOW CURRENT IS GENERATED
shown either separately or together.
Back to the Amber
In the non-theatrical version the first subject begins with a brief review of the development of Electrical Science and its effect upon civilization. The opening scene shows the ancient Greeks studying the electrical attraction manifested by amber when rubbed with cat's fur. The next step in the advance of electrical science is illustrated by Galvani's experiment with frog legs by which he discovered that electricity could be produced chemically, and which ultimately made the battery possible.
Following this comes Faraday's demonstration of how electricity could be generated by a magnet, and then the electric dynamo which this discovery brought into existence.
After this an intimate view is shown of Steinmetz and Edison at work and then come glimpses of the way electric power is generated and utilized at the present time. Electric Lighting, Radio, X-Ray, Household Appliances, the Electric Furnace, Trolley Cars, Elevated Trains and Electric Locomotives are all shown in operation.
