Steam Car
A steam car is a car (automobile) propelled by a steam engine. A steam engine is an external combustion engine (ECE) in which the fuel is combusted outside of the engine, unlike an internal combustion engine (ICE) in which fuel is combusted inside the engine. ECEs have a lower thermal efficiency, but carbon monoxide production is more readily regulated. Steam-powered automobiles were popular with early buyers. Steam was safe, reliable, and familiar. People had decades of experience with it in trains and boats, and even in experimental road vehicles. However, early steam cars required constant care and attention—and up to 30 minutes to start. Automated quick-firing boilers solved these problems, but not before more efficient gasoline engines dominated the market and made steam cars obsolete. The first experimental steam-powered cars were built in the 18th and 19th centuries, but it was not until after Richard Trevithick had developed the use of high-pressure steam around 1800 ...

Steam Boiler
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. ...

French People
The French people (french: Français) are an ethnic group and nation primarily located in Western Europe that share a common French culture, history, and language, identified with the country of France. The French people, especially the native speakers of langues d'oïl from northern and central France, are primarily the descendants of Gauls (including the Belgae) and Romans (or Gallo-Romans, western European Celtic and Italic peoples), as well as Germanic peoples such as the Franks, the Visigoths, the Suebi and the Burgundians who settled in Gaul from east of the Rhine after the fall of the Roman Empire, as well as various later waves of lower-level irregular migration that have continued to the present day. The Norse also settled in Normandy in the 10th century and contributed significantly to the ancestry of the Normans. Furthermore, regional ethnic minorities also exist within France that have distinct lineages, languages and cultures such as Bretons in Brittany ...

Flemish People
The Flemish or Flemings ( nl, Vlamingen ) are a Germanic ethnic group native to Flanders, Belgium, who speak Dutch. Flemish people make up the majority of Belgians, at about 60%. "''Flemish''" was historically a geographical term, as all inhabitants of the medieval County of Flanders in modern-day Belgium, France, and the Netherlands were referred to as "Flemings", irrespective of their ethnicity or language. The contemporary region of Flanders comprises a part of this historical county, as well as parts of the medieval duchy of Brabant and the medieval county of Loon, where the modern national identity and culture gradually formed. History The sense of "Flemish" identity increased significantly after the Belgian Revolution. Prior to this, the term "Vlamingen" in the Dutch language was in first place used for the inhabitants of the former County of Flanders. Flemish, however, had been used since the 14th century to refer to the language and dialects of both the peoples ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdinand Verbiest
Father Ferdinand Verbiest (9 October 1623 – 28 January 1688) was a Flemish Jesuit missionary in China during the Qing dynasty. He was born in Pittem near Tielt in the County of Flanders (now part of Belgium). He is known as Nan Huairen () in Chinese. He was an accomplished mathematician and astronomer and proved to the court of the Kangxi Emperor that European astronomy was more accurate than Chinese astronomy. He then corrected the Chinese calendar and was later asked to rebuild and re-equip the Beijing Ancient Observatory, being given the role of Head of the Mathematical Board and Director of the Observatory. He became close friends with the Kangxi Emperor, who frequently requested his teaching in geometry, philosophy and music. Verbiest worked as a diplomat, cartographer, and translator; he spoke Latin, German, Dutch, Spanish, Hebrew, Italian and Manchu. He wrote more than thirty books. During the 1670s, Verbiest designed what some claim to be the first ever self-propelled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autobus Amedee-bollee
A bus (contracted from omnibus, with variants multibus, motorbus, autobus, etc.) is a road vehicle that carries significantly more passengers than an average car or van. It is most commonly used in public transport, but is also in use for charter purposes, or through private ownership. Although the average bus carries between 30 and 100 passengers, some buses have a capacity of up to 300 passengers. The most common type is the single-deck rigid bus, with double-decker and articulated buses carrying larger loads, and midibuses and minibuses carrying smaller loads. Coaches are used for longer-distance services. Many types of buses, such as city transit buses and inter-city coaches, charge a fare. Other types, such as elementary or secondary school buses or shuttle buses within a post-secondary education campus, are free. In many jurisdictions, bus drivers require a special large vehicle licence above and beyond a regular driving licence. Buses may be used for scheduled bus ...

Muffler
A muffler (North American and Australian English) or silencer (British English) is a device for reducing the noise emitted by the exhaust of an internal combustion engine—especially a noise-deadening device forming part of the exhaust system of an automobile. Description Mufflers are installed within the exhaust system of most internal combustion engines. The muffler is engineered as an acoustic device to reduce the loudness of the sound pressure created by the engine by acoustic quieting. The noise of the burning-hot exhaust gas exiting the engine at high speed is abated by a series of passages and chambers lined with roving fiberglass insulation and/or resonating chambers harmonically tuned to cause destructive interference, wherein opposite sound waves cancel each other out. An unavoidable side effect of this noise reduction is the restriction of the exhaust gas flow, which creates back pressure, which can decrease engine efficiency. This is because the engine exh ...

Flash Boiler
A flash boiler is a type of water-tube boiler. The tubes are close together and water is pumped through them. A flash boiler differs from the type of monotube steam generator in which the tube is permanently filled with water. In a flash boiler, the tube is kept so hot that the water feed is quickly flashed into steam and superheated. Flash boilers had some use in automobiles in the 19th century and this use continued into the early 20th century. History There is disagreement about the exact definition of a flash boiler. Some writers use the term interchangeably with monotube boiler and there is even use of the term ''semi-flash boiler''. However, the flash boiler is generally attributed to Léon Serpollet who used a flash boiler in the Gardner-Serpollet steam-powered car from 1896. Serpollet's boiler was a low-water-content type with thick-walled tubes to provide a store of heat. Serpollet patented a steam generator in 1888, US Patent 379,421, but this is an early version whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operating Temperature
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating temperature). Outside this range of safe operating temperatures the device may fail. It is one component of reliability engineering. Similarly, biological systems have a viable temperature range, which might be referred to as an "operating temperature". Ranges Most devices are manufactured in several temperature grades. Broadly accepted grades are: *Commercial: 0 ° to 70 °C *Industrial: −40 ° to 85 °C *Military: −55 ° to 125 °C Nevertheless, each manufacturer defines its own temperature grades so designers must pay close attention to actual datasheet spec ...

Battery (electricity)
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery use ...
