In December 1878 Edison succeeded in making the first practical and economical light for domestic use. Edison’s greatest project was a workable direct-current electric light system that would replace candles and gaslight. But another inventor, Nikola Tesla, invented the superior system of alternating current that we take for granted today. A battle was soon to be underway between these two geniuses of the time, over which was the best source of electric energy. Edison and Tesla's later inventions, and Tesla’s fall from fame end the presentation. Included are many historical pictures and some short movie clips. Both technical and nontechnical audiences can appreciate this story.
