Pelton wheel
Pelton died in California at the age of seventy-eight and is interred at his family cemetery site in Vermilion, Ohio. His "Pelton Runner" design is still used to produce hydroelectric power in the United States and around the world, as shown here. Later designs such as the Turgo turbine, first patented in 1919, and the Banki turbine were inspired by the Pelton wheel.
