Power House Museum
The History of Hydroelectric Power exhibit focuses on the Belknap Mill power house and contains live demonstrations of the history of hydroelectric power and the vital role it played in the American Industrial Revolution.
Working models provide hands-on experience in how water wheels and turbines work, and an electrical panel with switches gives the visitor a chance to see the setup that sent excess power generated at the mill to supply the city with electricity.
The power house also has the actual gears used at the mill, with their wooden cogs, along with belts connecting the generators and flywheels. Storyboards assist with explanations of the evolution from water power to hydroelectric power, and visitors are able to walk among the machinery for up-close examination of the equipment.
