Benoît Fourneyron
Benoît Fourneyron (31 October 1802 – 31 July 1867) was a French engineer, born in Saint-Étienne, Loire. Fourneyron made significant contributions to the development of water turbines. Benoît Fourneyron was educated at the École Nationale Supérieure des Mines de Saint-Étienne, a nearby engineering school that had recently opened. After he graduated in 1816, he spent the next few years in mines and ironworks. Around this time, a number of French engineers—including some of Fourneyron's former teachers—were starting to apply the mathematical techniques of modern science to the ancient mechanism called the waterwheel. For centuries, waterwheels had been used to convert the energy of streams into mechanical power, mostly for milling grain. But the new machines of the Industrial Revolution required more power, and by the 1820s there was enormous interest in making waterwheels more efficient.

Saint-Étienne
Saint-Étienne (; frp, Sant-Etiève; oc, Sant Estève, ) is a city and the prefecture of the Loire department in eastern-central France, in the Massif Central, southwest of Lyon in the Auvergne-Rhône-Alpes region. Saint-Étienne is the thirteenth most populated commune in France and the second most populated commune in Auvergne-Rhône-Alpes. Its metropolis (''métropole''), Saint-Étienne Métropole, is the third most populous regional metropolis after Grenoble-Alpes and Lyon. The commune is also at the heart of a vast metropolitan area with 497,034 inhabitants (2018), the eighteenth largest in France by population, comprising 105 communes. Its inhabitants are known as ''Stéphanois'' (masculine) and ''Stéphanoises'' (feminine). Long known as the French city of the "weapon, cycle and ribbon" and a major coal mining centre, Saint-Étienne is currently engaged in a vast urban renewal program aimed at leading the transition from the industrial city inherited from the 19th ...

Water Turbine
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy. History Water wheels have been used for hundreds of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The migration from water wheels to modern turbines took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. Swirl The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβη" ...

Politicians From Auvergne-Rhône-Alpes
A politician is a person active in party politics, or a person holding or seeking an elected office in government.

Broadly speaking, a politician can be anyone who seeks to achieve political power in a government. Identity Politicians are people who are politically active, especially in party politics. Political positions range from local governments to state governments to federal governments to international governments. All ''government leaders'' are considered politicians. Media and rhetoric Politicians are known for their rhetoric, as in speeches or campaign advertisements. They are especially known for using common themes that allow them to develop their political positions in terms familiar to the voters. Politicians of necessity become expert users of the media. Politicians in the 19th century made heavy use of newspapers, magazines, and pamphlets, as well ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Saint-Étienne
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form " people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural ...

Cavan Water Mill
Cavan Water Mill, formerly Lifeforce Mill, is a 19th-century mill located in Cavan. The current building dates from 1846 and contains a notable MacAdam water turbine. Having been abandoned in the 1960s, it was restored as a museum and visitor attraction in the 1990s. History of the site Milling on this site can be traced back to the 14th century, when there was a Franciscan mill in the same location. The current mill was established by the Greene family in 1846. During the 1840s, there were 90 working water mills in County Cavan, but at the time this mill was built it was the only one within a two-mile radius. The building operated as a mill for more than a century until its closure in the 1960s. Following restoration, it operated again for a short while as a working mill for the creation of wholemeal flour for Lifeforce Foods. Design of the building The two-storey design has a three-bay extension at split level to the west and a two-storey return to the side. An adjacent mi ...

Niagara Falls
Niagara Falls () is a group of three waterfalls at the southern end of Niagara Gorge, spanning the border between the province of Ontario in Canada and the state of New York in the United States. The largest of the three is Horseshoe Falls, which straddles the international border of the two countries. It is also known as the Canadian Falls. The smaller American Falls and Bridal Veil Falls lie within the United States. Bridal Veil Falls is separated from Horseshoe Falls by Goat Island and from American Falls by Luna Island, with both islands situated in New York. Formed by the Niagara River, which drains Lake Erie into Lake Ontario, the combined falls have the highest flow rate of any waterfall in North America that has a vertical drop of more than . During peak daytime tourist hours, more than of water goes over the crest of the falls every minute. Horseshoe Falls is the most powerful waterfall in North America, as measured by flow rate.
