  • Business Tycoons In Us - 1,439 words
    Business Tycoons In US "The Business of the United States is Business," a great man once said. The United States has heralded around the globe for its incredible economic system. The growth of the United States started off small with minor discoveries and inventions, such as oil and electricity, and with those in place emergence of new technologies and innovations came underway. The railroads came about very slowly and became very popular. A man named Henry Bessemer came up with a way to make steel cheaply and efficiently (Bessemer Process). With the prices of steel dropping railroads were being built all across the nation. Major business tycoons, such as John D. Rockefeller and Andrew Carne ...

  • Electric Cars - 1,506 words
    Electric Cars Electric Cars History: Early electric vehicles may have appeared as early as 1830. Scottish inventor Robert Davidson constructed the world's first prototype electric vehicle in 1837, but historians generally credit J.K. Starley, an English inventor, and Fred M. Kimball of Boston with building the first practical electric cars in 1888. Later in the in the decade, William Morrison of Des Moines, Iowa, constructed his version of the electric vehicle in 1891. His vehicle required 24 storage battery cells, took 10 hours to charge, and could run for 13 hours. It could carry up to 12 people and had a 4-horsepower motor. His car could reach speeds up to 14 miles per hour. Morrison, how ...

  • Electric Cars - 855 words
    Electric Cars In numerous cities across the country, the personal automobile is the single greatest polluter, as emissions from million of vehicles on the road add up. Car pollution is one of the biggest polluters the solution is to have much more efficient vehicles that produce fewer emissions with every mile. So what would be the best thing for cars to run off of in the future? Electric vehicles are the answer to this problem. Electric vehicles or EVs, are vehicles that are powered by an electric motor instead of an internal combustion engine (Frequently). EVs use electricity as the "fuel" instead of gasoline or some other combustible fuel. The power for the vehicle is stored in many large ...

    English 1A 11/24/99 Submarines: The Underwater War The submarine is one of the greatest naval inventions in the history of war. This innovation allows men to dive to certain depths in the open seas at will. Submarines were equipped with weapons and communication devices. The submarine could stay at sea for months at a time and only required a few men to operate. They were small, quick, and hard to locate by larger ships. The submarine was thought to be the perfect naval vessel. The concept of the submarine dates back to Archimedes, the ancient mathematician, who "dreamed of building war vessels that could submerge at will and operate under the sea, so that they might sink the enemy without f ...

  • Hydrogen Car - 878 words
    Hydrogen Car The trouble with today's cars is that they still put out a lot of pollution, and use up fossil fuels. One day, we have to run out of fossil fuels. People have been talking about running cars on water for ages. Unfortunately, most of the time, these people are crackpots. But there is a certain amount of truth in what they say. Now I know that trying to predict the future is hard, but I think that an electric car, powered by a fuel cell running on hydrogen, could be a goer! If you remember back in chemistry classes at school, water is H2O. In other words, a molecule of water is made up of two atoms of hydrogen, and one atom of oxygen. If you use energy, and pass electricity throug ...

  • Internalcombustion Engine - 1,591 words
    INTERNAL-COMBUSTION ENGINE INTRODUCTION Internal Combustion Engine, a heat engine in which the fuel is burned ( that is, united with oxygen ) within the confining space of the engine itself. This burning process releases large amounts of energy, which are transformed into work through the mechanism of the engine. This type of engine different from the steam engine, which process with an external combustion engine that fuel burned apart from the engine. The principal types of internal combustion engine are : reciprocating engine such as Otto-engine, and Diesel engines ; and rotary engines, such as the Wankel engine and the Gas-turbine engine. In general, the internal combustion engine has bec ...

At the end of the compression stroke vaporized fuel is injected into the combustion chamber Fig. 3, Four-Stroke Diesel Engines. and burns instantly because of the high temperature of the air in the chamber. Some diesels have auxiliary electrical ignition systems to ignite the fuel when the engine starts, and until it warms up. This combustion drives the piston back on the third or power stroke of the cycle. The fourth stroke, as in the Otto-cycle engine, is an exhaust stroke. The efficiency of the diesel engine, which is in general governed by the same factors that control the efficiency of Otto-cycle engines, is inherently greater tha ...

    ... nal air pollution legislation appeared until the 50's. The first federal legislation appeared in 1955 when the Air Pollution Control Act was passed. In 1965 the Motor Vehicle Air Pollution Act was passed, establishing national automobile emission regulations for the first time. Then the Air Quality Act of 1967 was passed, providing funds for additional federal research and designating air quality control regions to help establish air pollution criteria. Another goal of this act was to research the cost -effectiveness relation of available engineering control techniques. Later, during the 70's National Air Quality Standards were set for the major pollutants. Primary standards were set for ...

  • Steam Engine - 690 words
    Steam Engine The steam engine was an engine powered by steam. It provided an important source of power independently. The steam engine played a major role in manufacturing and transportation during the Industrial Revolution. The challenge of improving the steam engine was the beginning of the science of thermodynamics. The steam engine was a very important invention. Steam can be made at any time simply by boiling water, so it is more dependable than wind or water energy (Norbeck 34-36). The heating and cooling of steam in cylinder causes pistons to move up and down. The simplest of a steam engine is used as a boiler. This was a common household heating system. The efficiency of the steam en ...

  • The Applications Of Technology In The First Decade Of The Twentyfirst Century - 1,500 words
    The Applications of Technology in the First Decade of the Twenty-First Century The Applications of Technology in the First Decade of the Twenty-First Century A quote I heard many times when I was in high school and which I now know traces back to Sir Francis Bacon, one of our earliest scientist or philosophers as they were then called, is the statement "Knowledge Is Power." Today, I believe that the fuller, more correct statement is to say, "the application of knowledge is power." The study of science, and technology subjects will broader our opportunities in life. As we continue to advance to the 21st century- now lesser than 30 days away-we are well aware that technology is possibly the ho ...

  • The Making Of Automobiles Started In The Year 1770 In 1770 A Man Named Nicholas - 997 words
    The making of automobiles started in the year 1770. In 1770 a man named Nicholas Joseph Cungnot from France built a large steam-driven vehicle. The vehicle didnt last long because the vehicle could only be driven for 12 to 15 minutes before running out of steam and the vehicle was too heavy and had poor balance and made it difficult to steer. Nothing more had been done until in the 1784. In 1784 James Watt made a patent on a steam carriage, but nothing became of it. Then in 1785 John Fitch invented a steam-propelled boat in New Jersey. And then in 1786 he organized a company to build the steam engines and then even built a model of a road vehicle with an engine but committed suicide before a ...

  • The Stirling Engine - 1,331 words
    The Stirling Engine The Stirling Engine Robert Stirling invented the Stirling engine in 1816. At the time he was a Scottish minister. Stirling engines were the safest engines made during that time period that would not explode like a steam engine could. The Stirling engine would not explode because the pressures could not be elevated to that to such a high level. The machine simply stopped when the heater section failed from thermal stress or imperfections in the material or manufacturing process. So from that day on there was a better, safer way to produce power, far superior than that of a steam engine. A Stirling Engine is a mechanical device, which operates on a closed looping thermodyna ...
