Continuing his American journey heading west through New York State, Michael has a lightbulb moment in Schenectady, when he discovers how Thomas Edison's General Electric Company also leads the way in modern rail technology. In Utica, he investigates lock 20 of 57 along the early 19th-century Erie Canal, 325 miles of waterway which connected the Great Lakes with the Atlantic Coast via the Hudson River. Further west in Rochester, Michael discovers a famous 19th-century name still trading today - George Eastman, who launched mass market photography with his Eastman Kodak company. Reaching Buffalo, he lunches on the city's famous Buffalo wings and discovers it was once the centre of the world's grain trade. Touring Silo City, Michael learns about the invention which propelled the port of Buffalo into its dominant position, the grain elevator, and how the railroads sealed the deal.
