Inscription. The use of wheels to convert flowing or falling water into power began in ancient Greece around the third to the first century B.C. In 1878 Lester Allan Pelton, a carpenter and blacksmith from Nevada City, invented a new design for an impulse water turbine. Pelton's wheels would eventually become the standard design for exploiting the energy potential of water. Using high pressure and low volume, Pelton's wheel took advantage of the impulse energy of moving water. Water entered the middle of the bucket, splitting into two streams that followed the contour of the bucket and exited out the sides. This highly efficient and revolutionary design allowed the water to transfer most of its kinetic energy to the wheel more so than any previous design. Pelton wheels are still used around the world in the hydroelectric industry. This wheel was used at the Camp 9 Powerhouse on the Stanislaus River until decommissioned and gifted to the museum by P.G&E.

3. Hydraulic Turbines: The Pelton Turbine. The Pelton Turbine has a circular disk mounted on the rotating shaft or rotor. This circular disk has cup shaped blades, called as buckets, placed at equal spacing around its circumference. Nozzles are arranged around the wheel such that the water jet emerging from a nozzle is tangential to the circumference of the wheel of Pelton Turbine.
