|  Essay on Otto Hahn and the Discovery of Nuclear Fission |
|
| Otto Hahn and the Discovery of Nuclear Fission Research Paper, Custom Essays and Term Papers Writing on Energy & Fuel. Born into the family of a Frankfurt glazier, Otto Hahn studied chemistry at the University of Marburg, earning his doctorate in 1901. He served briefly in the military, then taught at Marburg before moving to London in 1904. Here he worked at University College with the British scientist Sir William Ramsay. The two men studied phenomena associated with radioactivity, and, in the course of this work, Hahn discovered the existence of a new radioactive substance, radiothorium, a breakthrough that, with Ramsay's help, earned Hahn a post on the faculty of the University of Berlin. Before beginning his duties there, Hahn worked briefly with the British physicist Ernest Rutherford... |

| Essay on Fossil Fuel Reserves |
|
| Fossil Fuel Reserves Research Paper, Custom Essays and Term Papers Writing on Energy & Fuel. Estimates in 2005 placed the amount of fossil fuels consumed to that point at approximately 1.1 trillion barrels of oil, meaning that nearly half of the total reserves had been used up. At a rate of 83 million barrels per year, this predicts that the remaining fuel will last until approximately 2036. Given that fossil fuel consumption has been increasing steadily over the last 50 years, these predictions could be overestimates. For example, in June 2008, the U.S. Energy Information Administration projected energy consumption to increase by 57 percent from 2004 to 2030. The most credible predictions of fossil fuel expenditures and lifetime were made by the Shell Oil geophysicist... |

| Essay on The Development of Nuclear Power |
|
| The Development of Nuclear Power Research Paper, Custom Essays and Term Papers Writing on Energy & Fuel. Strictly speaking, nuclear power should not figure at all in a work devoted primarily to the first half of the twentieth century, for the world's first commercial nuclear power station - at Calder Hall in Britain - did not become operational until 1956. Nevertheless, its technological roots stretch well back into the period of our present concern and it is most intimately connected with the Manhattan Project which produced the atom bomb that so abruptly terminated the Second World War. Equally, were we to trace nuclear power back to its ultimate scientific origins we would be guilty not of going beyond the end of our present period but of anticipating its start. The key... |

| Essay on Natural Power Resources |
|
| Natural Power Resources Research Paper, Custom Essays and Term Papers Writing on Energy & Fuel. In a sense all power is natural, in that it is obtained by harnessing the resources of nature. Coal and oil, for example, have lain buried in the earth's crust for many millions of years. They can be burned to produce heat which in turn can be converted to mechanical energy, as in steam-engines and internal combustion engines. Such engines can, in turn, be used to generate electricity in accordance with well-understood natural laws. Even uranium, the newest large-scale source of power, is natural in that it is just as much a mineral as oil or coal. Today, however, natural power is generally taken to comprise the power of the sun, the tides, rivers, wind, the heat of the earth's crust, and so on... |

| Essay on Natural Gas Usage |
|
| Natural Gas Usage Research Paper, Custom Essays and Term Papers Writing on Energy & Fuel. In America the gas industry developed very differently from that in Europe. Initially, it was quick to adopt the coal carbonization process: the streets of Baltimore were lit by coal gas as early as 1816. But in areas where natural gas was available -- it was often encountered at quite shallow levels in the search for petroleum -- it was piped away for domestic and industrial use. Although attempts to utilize natural gas in America can be traced back at least to 1821, the first commercial success seems to have been at Titusville in 1873. Thereafter, the natural-gas industry expanded enormously and transmission over long distances became commonplace. Between 1935 and 1950 sales of natural gas... |

| Essay on Fossil Fuels: Coal, Gas, and Petroleum |
|
| Fossil Fuels: Coal, Gas, and Petroleum Research Paper, Custom Essays and Term Papers Writing on Energy & Fuel. Of the fossil fuels coal, as we have seen, retained a commanding position throughout the first half of 20th century, though world output after the First World War remained fairly static. If we look at individual countries, however, the situation is rather different: there were considerable differences in the uses to which coal was put and in the economics of its production. In some countries, such as Germany and Austria, the variety known as lignite was extensively mined. This is a brown coal, with a low calorific value, that is intermediate between peat and the hard black bituminous coals familiar in Britain. Again, not all coals are suitable for the manufacture of... |

| Essay on The Changing Patterns of Energy Sources |
|
| The Changing Patterns of Energy Sources Research Paper, Custom Essays and Term Papers Writing on Energy & Fuel. Changes in the source and utilization of energy again reveal the first half of the twentieth century as a period of transition. In 1900 industrial and domestic demands for energy were growing rapidly, but lack of energy was not seen as any bar to technological advance. There were vast reserves of coal cheaply available, and the petroleum industry, though still in its infancy, clearly represented a major new source of fossil fuel. Coal had long been the basis of a flourishing and expanding gas industry. Electricity represented a new and flexible kind of energy whose potential value was already becoming clear. Although its production depended largely on generating steam in coal-fired... |

| Essay on The Steam Turbine and Power Stations |
|
| The Steam Turbine and Power Stations Research Paper, Custom Essays and Term Papers Writing on Energy & Fuel. As a result of the development of electricity, water power came into its own during the nineteenth century. The scientists set about to find the proper formula to design and construct water wheels. The mathematical approaches of Euler and Manoury in 1813 enabled Fourneyron to improve the water wheel and to make it once more a serious competitor of the steam engine. More efficient structures were developed by Henschel and Jonvel in 1837. In the late 1860's, Bergier, a papermaker of Grenoble, France, began to use water from the mountains to move his water wheels. It was he who introduced the term houille blanche (white coal) to designate water power. The problem of using water wheels... |

| Essay on The Applications of Electricity |
|
| The Applications of Electricity Research Paper, Custom Essays and Term Papers Writing on Energy & Fuel. The development of batteries and generators created, as we have seen, the possibility of supplying electricity on a large scale. The first important application was the transformation of electricity into mechanical energy by means of the electric motor. It is strange, indeed, to find that, though generator and electric motor clearly work on the same principle, their development for a long time followed different lines. The earlier models by Faraday and Barlow, demonstrating the principle of the electric motor, were mere toys. Thomas Davenport, buying one of Henry's electromagnets, succeeded in developing a practical electric motor in 1835. Improving his first patent application... |

| Essay on Generating and Transmitting Electricity |
|
| Generating and Transmitting Electricity Research Paper, Custom Essays and Term Papers Writing on Energy & Fuel. Though in the nineteenth century the old sources of power continued in use, their relative importance changed greatly. The windmill remained in use for drainage purposes. Because of their limited power, windmills were soon displaced in industry by steam engines, which came to the fore very rapidly, but were not unchallenged. The eighteenth-century experiments with electricity in laboratories and salons had soon led to research into the possibilities of storing electricity. The famous Leyden jar, invented simultaneously in 1745 by a German Lutheran pastor and a Dutch scientist, van Musschenbroek, gave little more than a flash of "static" electricity when discharged. A regular supply... |
