Hydroelectric Engineering
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Bernard Forest De Bélidor
Bernard Forest de Bélidor (1698, Catalonia, Spain – 8 September 1761, Paris, France) was a French engineer, significant to the development of the science of hydraulics and ballistics. He was the son of Jean Baptiste Foret de Belidor, an officer of dragoons, and his wife, Marie Héber but was orphaned at five months old and brought up by the family of his godfather, an artillery officer named de Fossiébourg. Bélidor enlisted in the army at a young age. After leaving the army, he developed an interest in science and engineering, and became professor at the school of artillery of La Fère in Aisne. For a while he worked on measuring the Circle, arc of the earth. In the years to come he published several works of great importance, on a wide range of subjects, including hydraulics, mathematics, and civil engineering, civil and military engineering. His most famous book is ''L'architecture hydraulique'' (published in four volumes from 1737 to 1753). Here, integral calculus is used ...

Thomas Alva Edison
Thomas Alva Edison (February11, 1847October18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest. Early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanical laboratory in Fort Myers, Florida, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niagara Falls
Niagara Falls is a group of three waterfalls at the southern end of Niagara Gorge, spanning the Canada–United States border, border between the Provinces and territories of Canada, province of Ontario in Canada and the state of New York (state), New York in the United States. The largest of the three is Horseshoe Falls, which straddles the Canada–United States border, international border of the two countries. It is also known as the Canadian Falls. The smaller American Falls and Bridal Veil Falls (Niagara Falls), Bridal Veil Falls lie within the United States. Bridal Veil Falls is separated from Horseshoe Falls by Goat Island (New York), 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 before flowing out to the Atlantic Ocean through the St. Lawrence River, the combined falls have the List of waterfalls by flow rate, highest flow rate of any waterfall in North ...

Schoellkopf Power Station
The Schoellkopf Power Station was built on land owned by Jacob F. Schoellkopf above the Niagara Gorge near the American Falls, downriver from Rainbow Bridge (Niagara Falls), Rainbow Bridge. Understanding the growing need for electricity and the role of harnessing the Falls, Schoellkopf purchased the land for the hydraulic canal on May 1, 1877 for $71,000. After his death in 1903, his sons took over the operation of the power business. In 1918, Schoellkopf's Niagara Falls Hydraulic Power and Manufacturing Company merged with the Niagara Falls Power Company, which was owned by Edward Dean Adams. Much of the site is, as of 2014, occupied by the Maid of the Mist tour boat company as a maintenance area and off-season boat storage yard. The power station remains form a part of a fully accessible tourist attraction associated with Niagara Falls State Park and is connected with its Niagara Gorge hiking trail system.

Arc Lamp
An arc lamp or arc light is a lamp that produces light by an electric arc (also called a voltaic arc). The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light. It was widely used starting in the 1870s for street and large building lighting until it was superseded by the incandescent light in the early 20th century. It continued in use in more specialized applications where a high intensity point light source was needed, such as searchlights and movie projectors until after World War II. The carbon arc lamp is now obsolete for most of these purposes, but it is still used as a source of high intensity ultraviolet light. The term is now used for gas discharge lamps, which produce light by an arc between metal electrodes through a gas in a glass bulb. The common fluorescent lamp is a low-pressure mercury arc lamp. The xenon arc lamp, which produces a high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
