Fourneyron-style turbines

Using the proposal of a former teacher (
Claude Burdin Claude Burdin (; 19 March 1788 – 12 November 1873) was a French engineer. Born in Lépin-le-Lac, Savoie, when it was known as the Duchy of Savoy, he was professor at the school of mines, École nationale supérieure des mines de Saint- ...
) as a guide, Fourneyron built in 1827, at age of 25, his first prototype for a new type of waterwheel, called a "turbine". (The term turbine is derived from the Greek word "τύρβη" for "whirling" or a "vortex".) In Fourneyron's design, the wheel was horizontal, unlike the vertical wheels in traditional waterwheels. This turbine used two sets of blades, curved in opposite directions, to get as much power as possible from the water's motion. Fourneyron won a 6,000 franc prize offered by the French Society for the Encouragement of Industry for the development of the first commercial hydraulic turbine. Over the next decade, Fourneyron built bigger and better turbines, learning from his mistakes after each new model. By 1837, he had a turbine capable of a fantastic 2,300 rotations per minute. On that model, the turbine's wheel was only one foot in diameter, and it weighed just 40 pounds. It operated at 80 percent efficiency. Within a few years, hundreds of factories used Fourneyron-style turbines. Other countries adopted the design to power their industrial machinery, too. Immediately successful, it powered industry in continental Europe and the U.S., notably the New England textile industry. In 1895 Fourneyron turbines were installed on the U.S. side of
