		The Pelton Wheel to generate electrical power was put in the later 50's with much of the planning being done by Wes Gibson an Engineer for Longview Fiber and camp committee members Joe Hunt, Gail Norton and Roy Parsons.
		The first dam built to service the water flow to the Pelton wheel proved to be too low and had to be moved higher up the creek after the building of the new lodge.
		The Pelton Wheel to generate electrical power was put in by John Weber, Joe Hunt, Gail Norton and Roy Parsons in 1959.

	Pelton wheel - Wikipedia, the free encyclopedia
		The pelton wheel turbine is a tangential flow impulse turbine, water flows along the tangent to the path of the runner.
		Pelton observed an increase in speed of the misaligned wheel.
		The smallest Pelton wheels, only a few inches across, are used with household plumbing fixtures to tap power from mountain streams with a few gallons per minute of flow, but these small units must have thirty meters or more of head.

	Water turbine - Wikipedia, the free encyclopedia
		The main difference between early water turbines and water wheels is a swirl component of the water which passes energy to a spinning rotor.
		In 1879, Lester Pelton, experimenting with a Knight Wheel, developed a double bucket design, which exhausted the water to the side, eliminating some energy loss of the Knight wheel which exhausted some water back against the center of the wheel.
		Pelton wheels may be either vertical or horizontal shaft machines because the size of the machine is so much less than the available head.

	Planetary Swing-by and the Pelton Turbine
		Lester Pelton, the inventor of the device, was born in 1829 in Vermillion, Ohio, on the shores of Lake Erie.
		Therefore, instead of the slow (and inefficient) water wheels traditionally used by flour mills, which needed only a moderate height but used a large amount of water, mine owners installed turbines--wheels with cups around their circumference, on which a fast jet of water was directed, coming from a high-up reservoir.
		Pelton was watching a spinning water turbine when the key holding its wheel onto its shaft slipped, causing it to become misaligned.

	Pelton wheel : Water turbine
		There are multiton pelton wheels mounted on vertical oil pad bearings in the generator houses of hydroelectric plants.
		The smallest pelton wheels, only a few inches across, are used with household plumbing to tap power from mountain streams with a few gallons per minute of flow, but thirty meters or more of head.
		Supposedly Pelton discovered his wheel by noticing how water splashed out of the nostrils of a cow as it drank from a stream.

		In the ideal Pelton wheel, a water jet impinges on a bucket which is curved to reverse the direction of the water's flow without reducing the water's speed.
		If our wheel speeds are 1500 and 3000 rpm, and we want, say, 10 V out of our generator, then we need servo motors with 150 and 300 rpm per volt, or 6 and 3 volts per 1000 rpm.
		If there is no load on the wheel, the wheel will try to go as fast as the water jet, with the result that there will be no change in the water's speed and hence no torque.

		Cussons P6240 Pelton Wheel, although a model, reproduces all the characteristics of full size machines and allows an experimental program to determine both the performance of the turbine and to verify design theory.
		The design of the Degener Pelton Wheel follows typical industrial practice with a horizontal shaft, single horizontal jets produced by a single nozzle fitted with a needle or spear regulator, and a wheel fitted with multiple (16) elliptical ridged buckets at a mean diameter of 100mm.
		Position the Pelton Wheel base plate on the working surface of the Hydraulics Bench straddling the weir channel so that the nozzle is at the left hand side and ensuring that the four location pegs engage in the four holes in the base plate.

	Pelton turbine
		Also called a free-jet turbine or Pelton wheel, a type of impulse turbine, named after L. Pelton who invented it in 1880.
		The runner is fixed on a shaft, and the rotational motion of the turbine is transmitted by the shaft to a generator.
		Pelton turbines are suited to high head, low flow applications; they are used in storage power stations with downward gradients up to 2000 meters and can contain up to 6 nozzles.

		The Pelton Wheel Monument stands alongside the town’s main street, along with a small wooden building labeled “Jail.” The monument reads, “On this spot in 1878, Lester Allen Pelton invented the Pelton water wheel.
		Pelton noticed how the water divided into two streams when it bounced off the cow’s nose, due to the ridge between its nostrils.
		Pelton applied this observation to a metal cup and the Pelton Wheel was born.

	Camptonville
		The town’s most famous citizen was unquestionably Lester Pelton, the inventor of the Pelton Wheel which was long used in mining machinery and electric generators.
		Pelton’s wheel was an immense improvement over the water wheel in use at the time.
		Pelton designed a cup which was divided by a kind of sloping ridge that channeled the stream of water away to each side, allowing all of the force from the stream to be used to turn the wheel.

	Pelton, Lester Allen (Site not responding. Last check: 2007-10-19)
		The Pelton wheel remains the only hydraulic turbine of the impulse type in common use today.
		The energy to drive these wheels was supplied by powerful jets of water which struck the base of the wheel on hemispherical cups.
		Pelton's discovery was that the wheel rotated more rapidly, and hence developed more power, with the jet striking at the inside edge of the cups, rather than the centre; he built a wheel with split cups.

		In contests against other wheels of the time, the Pelton was the most efficient, extracting the most power from a given water source.
		The Pelton Water-Wheel Company was founded in 1888 in San Francisco and produced wheels up into the 1920s.
		The purpose of the nozzle feeding water to a Pelton wheel is to convert the water's pressure into velocity.

	Welcome to Deer Creek School's "Our Town" Project - People - Lester Pelton
		Pelton did not want to be a miner so he decided to improve mining methods.
		Pelton knew the forests were disappearing so he began thinking about inventing a water wheel.
		Lester Pelton’s invention was the beginning of the development of hydroelectric power and is still used throughout the world today.

	Turbines
		At Laxey, on the Isle of Man, an overshot wheel of 70 ft diameter, rotating at 2.5 rpm and developing 175 hp, was fed by water under pressure that rose in a masonry column and was then led to the top of the wheel in a wooden flume.
		Improvements in water wheels continued in the 19th century, by such engineers as Robert Fairbairn, and were brought to a high state of excellence with metal replacing most of the wood in both wheel and gearing.
		Pelton is a trade name for the products of the company he originated, but the term is now used generically for all similar impulse turbines.

		As is apparent from the drawings, this is an impulse wheel, driven by the impulses produced as water strikes revolving blades or buckets.
		In a perfectly designed wheel, the water strikes at high speed, exhausts its energy in driving the wheel to which the bucket is attached, and then falls free of the wheel.
		The hurdy-gurdy was a wheel that rotated in a vertical plane, had flat vanes fixed around its circumference, and was driven by the force of water striking the vanes.

		One particularly clear demonstration of this is with the blade of a turbine called the pelton wheel.
		The arrangement of a pelton wheel is shown in the figure below.
		This splitting of the jet is beneficial to the turbine mounting - it causes equal and opposite forces (hence a sum of zero) on the bearings.

	Professor Quester Answers - Hydroelectric Power
		The Pelton wheel had pairs of buckets stopping the water, turning a turbine and is connected to a generator.
		Water wheels were used for irrigation as long ago as 500 B.C.E., (before the common era), but water power was first used for grinding corn around 100 B.C.E. The type of water wheel used depended on how fast the stream or river flowed.
		I sorry I'm not able to help you construct a scale model of the Pelton turbine however the Pelton wheel is a flywheel system with pairs of "buckets" to stop the water and turn a belt that is connected to a generator.

		Later on, the water wheel came into use in Europe for grinding corn, for running sawmills, and for other similar purposes, but no inventor of the time was able to solve the problem of constructing a water wheel suited to any but the most moderate power.
		The wheel is rotated by the endeavors of the water to escape.
		The wheel which Pelton was repairing had gone a little crooked, and Pelton was sharp enough to notice that the jet of water coming from above and falling on one side of the buckets instead of into the middle did not splash and seemed to drive the wheel at increased speed.

		Pelton was born in Vermillion, Ohio in 1829 but later immigrated to California during the time of the gold rush.
		However, the Pelton was not lost completely because the Turgo was built on a design based on the Pelton turbine.
		(Bellis, Lester Allen Pelton 3) The key differences between the Pelton and the Turgo were that the Turgo was smaller for one, and cheaper to manufacture.

		If paddle wheels were made from high-speed Pelton wheels, for example, they would become "reaction" devices and the rules of the game would change dramatically.
		A Pelton wheel has cupped blades that almost completely reverse the direction of an impinging water jet, thereby captuing most of the momentum of that jet.
		The point of a "reverse pelton wheel" is that it is a high speed "reaction" device and those water wheels are basically low speed drag devices.
