Lowell, Massachusetts was incorporated in 1826 to serve as a mill town and was named after Francis Cabot Lowell, a local figure in the Industrial Revolution. The city became known as the cradle of the American Industrial Revolution, due to a large series of textile mills and factories. Many of the Lowell’s historic manufacturing sites were later preserved by the National Park Service to create Lowell National Historical Park. Emerson was a water turbine pioneer. America had taken the idea of the turbine from the French, and improved upon it. In 1870, Emerson had set up a remarkable new testing flume in Holyoke, Massachusetts. At that time, turbines wasted about a third of the energy in the water passing through them. When he’d finished, efficiencies were over ninety percent.
