In 1909, after eight years of research and more than $1 million spent, Thomas Edison completes a storage battery for use in electric streetcars and railways. The concept for Edison's battery, which uses an alkaline solution in place of an acid, is still used today in many transit applications. In the same year, Edison also predicts that overhead trolley systems will never be an effective means of transportation.
