Over 100 years ago, the great inventor Thomas Edison warned that gasoline cars would pollute the environment and lead to gasoline shortages. He preferred the use of clean electric vehicles. He also put his money where his mouth was and developed an entirely new alkaline storage battery system for his beloved cars, the nickel-iron storage battery. This battery turned out to have an incredible run of application and is still being used today. It was the most profitable product ever made by the Thomas A. Edison Company. Now many engineers, scientists, and researchers are helping people go back to Mr. Edison's original dream. Today one sees the emergence of hybrid cars and electric vehicles reducing the use of gasoline and helping to clean up the air in cities. A hybrid car has both a regular gasoline engine and batteries. In this article, the author discusses a classroom challenge that asks students to develop an "electric car" type of future. In this challenge, students will be engaged in developing a plan for the large-scale implementation of "electric cars"--a step-by-step blueprint of how they would massively introduce them into the transportation sector.
