Karl Kordesch
Karl Kordesch (18 March 1922 – 12 January 2011) was an Austrian chemist and inventor, most notable for jointly inventing the alkaline battery. In 1953 he moved to the United States as part of Operation Paperclip. Life Kordesch was born in Vienna. He studied chemistry and physics at the University of Vienna, and earned his doctoral degree in 1948. From 1948–53 he worked at the university's Chemical Institute. He was then recruited as a member of Operation Paperclip and moved to the United States, where from 1953–55 he was head of the Battery Division of the U.S. Signal Corps in Fort Monmouth. In 1955 he joined Union Carbide in Ohio, working with two fellow Austrians. He led two research groups: one concerned with the development of manganese dioxide batteries, the other devoted to fuel cells. During this time Kordesch filed 22 patents. In 1957, Karl Kordesch, Paul A. Marsal and Lewis Urry filed US patent (2,960,558) for the alkaline dry cell battery, which eventually became ...

Ohio
Ohio () is a state in the Midwestern region of the United States. Of the fifty U.S. states, it is the 34th-largest by area, and with a population of nearly 11.8 million, is the seventh-most populous and tenth-most densely populated. The state's capital and largest city is Columbus, with the Columbus metro area, Greater Cincinnati, and Greater Cleveland being the largest metropolitan areas. Ohio is bordered by Lake Erie to the north, Pennsylvania to the east, West Virginia to the southeast, Kentucky to the southwest, Indiana to the west, and Michigan to the northwest. Ohio is historically known as the "Buckeye State" after its Ohio buckeye trees, and Ohioans are also known as "Buckeyes". Its state flag is the only non-rectangular flag of all the U.S. states. Ohio takes its name from the Ohio River, which in turn originated from the Seneca word ''ohiːyo'', meaning "good river", "great river", or "large creek". The state arose from the lands west of the Appalachian Mountai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonia
Ammonia is an inorganic compound of nitrogen and hydrogen with the formula . A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Biologically, it is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to 45% of the world's food and fertilizers. Around 70% of ammonia is used to make fertilisers in various forms and composition, such as urea and Diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water. Although common in nature—both terrestrially and in the outer planets of the Solar System—and in wide use, ammonia is both caust ...

Hydrogen Fuel Cell
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied. The first fuel cells were invented by Sir William Grove in 1838. The first commercial use of fuel cells came more than a century later following the invention of the hydrogen–oxygen fuel cell by Francis Thomas Bacon in 1932. The alkaline fuel cell, also known as the Bacon fuel cell after its inventor, has been used in NASA space programs since the mid-1960s to generate power for satellites and space capsules. Since then, fuel cells have b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austin A40
A number of different automobiles were marketed under the Austin A40 name by Austin between 1947 and 1967. Austin's naming scheme at that time derived from the approximate engine output, in horsepower. Therefore, the models were also given names, originally based on counties of England. The following vehicles were sold under the Austin A40 name: * 1947–50 Austin A40 Dorset 2-door saloon * 1947–52 Austin A40 Devon 4-door saloon * 1947–56 Austin A40 Countryman 2-door estate car * 1947–56 Austin A40 Van 2-door panel van * 1947–56 Austin A40 Pick-up 2-door pick-up truck * 1948–5?

Fuel Economy In Automobiles
The fuel economy of an automobile relates distance traveled by a vehicle and the amount of fuel consumed. Consumption can be expressed in terms of volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses (wind resistance, tire drag, and others) encountered while propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning. Various strategies can be employed to reduce losses at each of the conversions between the chemical energy in the fuel and the kinetic energy of the vehicle. Driver behavior can affect fuel economy; maneuvers such as sudden accelerat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrazine
Hydrazine is an inorganic compound with the chemical formula . It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour. Hydrazine is highly toxic unless handled in solution as, for example, hydrazine hydrate (). Hydrazine is mainly used as a foaming agent in preparing polymer foams, but applications also include its uses as a precursor to polymerization catalysts, pharmaceuticals, and agrochemicals, as well as a long-term storable propellant for in-space spacecraft propulsion. Additionally, hydrazine is used in various rocket fuels and to prepare the gas precursors used in air bags. Hydrazine is used within both nuclear and conventional electrical power plant steam cycles as an oxygen scavenger to control concentrations of dissolved oxygen in an effort to reduce corrosion. the world hydrazine hydrate market amounted to $350 million. About two million tons of hydrazine hydrate were used in foam blowing agents in 2015. Hydrazines r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hybrid Electric Vehicle
A hybrid electric vehicle (HEV) is a type of hybrid vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system ( hybrid vehicle drivetrain). The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There is a variety of HEV types and the degree to which each function as an electric vehicle (EV) also varies. The most common form of HEV is the hybrid electric car, although hybrid electric trucks (pickups and tractors), buses, boats and aircraft also exist. Modern HEVs make use of efficiency-improving technologies such as regenerative brakes which convert the vehicle's kinetic energy to electric energy, which is stored in a battery or supercapacitor. Some varieties of HEV use an internal combustion engine to turn an electrical generator, which either recharges the vehicle's batteries or directly powers its electric drive motors; this combinatio ...

Puch MS 25 With Hydrazine-air Fuel Cell, Technisches Museum Wien
Puch () is a manufacturing company located in Graz, Austria. The company was founded in 1899 by the industrialist Johann Puch and produced automobiles, bicycles, mopeds, and motorcycles. It was a subsidiary of the large Steyr-Daimler-Puch conglomerate. History Foundation From 1889 Johann Puch (1862–1914) worked as an agent for Humber vehicles and manufacturer of ''Styria'' safety bicycles in a small workshop in Graz and in 1890 he founded his first company, Johann Puch & Comp., employing 34 workers. Cyclists like Josef Fischer, winning the first edition of Paris–Roubaix in 1896, popularized ''Styria'' bicycles which were even exported to England and France. By 1895, Puch already employed more than 300 workers producing about 6000 bikes a year. In 1897 Puch left the company after a dispute with his business partners. Two years later he founded the First Styrian Bicycle Factory AG (''Erste Steiermärkische Fahrradfabrik AG'') in Graz. Puch's company became successful thro ...

Expo '58
Expo 58, also known as the 1958 Brussels World's Fair (french: Exposition Universelle et Internationale de Bruxelles de 1958, nl, Brusselse Wereldtentoonstelling van 1958), was a world's fair held on the Heysel/Heizel Plateau in Brussels, Belgium, from 17 April to 19 October 1958. It was the first major world's fair registered under the Bureau International des Expositions (BIE) after World War II. Background Expo 58 was the eleventh world's fair hosted by Belgium, and the fifth in Brussels, following the fairs in 1888, 1897, 1910 and 1935. In 1953, Belgium won the bid for the next world's fair, winning out over other European capitals such as Paris and London. Nearly 15,000 workers spent three years building the site on the Heysel/Heizel Plateau, north-west of central Brussels. Many of the buildings were re-used from the 1935 World's Fair, which had been held on the same site. The theme of Expo 58 was ''"Bilan du monde, pour un monde plus humain"'' (in English: "Evalu ...
