Edison vs. Westinghouse I

Lead: One of the great struggles in the history of technology was that between Thomas Alva Edison and George Westinghouse.

Intro.: A Moment in Time with Dan Roberts.

Content: The use of electricity as a means of lighting homes, businesses and streets was in its infancy in the early 1880s. Thomas Edison had improved the incandescent light bulb and was hard at work constructing the power system for the City of New York. To get the power from generating power plants out to the customers, he used direct current which can be compared to a water flowing in a pipe. Power goes in one direction at a constantly low voltage over wiring that was very expensive so as to not blow out the light bulbs waiting for power down the circuit.

High Octane/High Test Gasoline

Lead: In the 1930s, oil companies were struggling to boost the octane of gasoline. Eugène Houdry’s catalytic cracking process made it possible and may have helped win World War II.

Intro.: A Moment in Time with Dan Roberts.

Content: When it comes from the ground, crude oil is almost useless, a mixture of thousands of different types of hydrocarbons: asphalt to gasoline to natural gas. Each has a different molecular weight, therefore, crude oil must be refined to pull out the impurities such as sulfur compounds and separate different components such as kerosene, gasoline, fuel oil, and so forth.
