- Fuel Cells, Flywheels And Hybrids - 731 words
Fuel Cells, Flywheels and Hybrids There are three types of experimental vehicle (EVs) propulsion technologies on the currently being tested. Batteries are currently the most popular power source for modern EVs but they are by no means the only available technology. A number of alternatives are under development and they, too, are well positioned to rival batteries as an effective EV power source. 1.Fuel cells Some of the most recent and exciting news in electric-vehicle development has centered around a new power source, called the fuel cell. The fuel cell utilizes a special membrane to generate electricity through the controlled reaction between hydrogen and oxygen atoms. Unlike batteries, ...

- Air And Water - 412 words
Air And Water A major transition in the modern energy age began in the 1970s, when the big nations industry started to grow up rapidly. The use of oil was very important and overnight, oil prices shot through the roof, and the trend of ever-cheaper, ever-more-plentiful energy sources were in need. Another player on the modern energy stage is nuclear power. An industry that didn't exist 40 years ago is now at a huge amount of production, producing 20 percent of the nation's electricity. Ironically, the industry is fading out. New orders ceased 20 years ago, and as aging plants reach the end of their lives, they are closing, one by one. All the non-renewable energy resources have positive and ...

- Apollo 13: A Successful Failure - 1,187 words
Apollo 13: A Successful Failure During a modification of Oxygen Tank No. 2 by NASA contractor, North American Rockwell, it was inadvertently dropped about 2 inches, which caused undetected damage to the interior assemblies. This damage eventually led the failure of the $400-million Apollo 13 mission. The crew of Apollo 13 was responsible for several scientific experiments that were to be carried out during the mission. Atmospheric electrical phenomena experiments were designed to study certain aspects of launch-phase electrical phenomena. An opportunity to study large mass impact phenomena on the Moon was available with this mission. Instead of sending the third stage of the launch vehicle i ...

- Apollo 13: A Successful Failure - 1,192 words
... t tank was leaking, apparently damaged by the blowout of tank No. 2, and the power was fading. Only the command module storage batteries were left in Apollo, and these would have to be used for reentry into Earth atmosphere. The lunar module was now the crew's only salvation. As the crew began moving into the Aquarius and shutting down the command module, navigators at Mission Control computed a new course that would swing the ship around the Moon and bring it back to Earth. At 2:43 a.m. CST, April 14th the crew made the first course correction. They had to fire the Lunar Modules engines for 30.7 seconds. This would increase the velocity 38 feet per second, which put the ship in a free r ...

- Automobile Industry - 1,462 words
Automobile Industry Industry Analysis The automobile industry began with Henry Fords production of the Model T in the early 1900s. With the creation of the assembly line, cars became cheaper and quicker to produce, thus making them affordable for many people. There were originally 500 auto manufacturers. By 1908, there were only 200; and in 1917 only 23 remained. This vast reduction was due to large amounts of consolidation within the industry. Currently, the major competitors within the industry are Ford, DaimlerChrylser, General Motors (GM), Honda, Toyota, and Volkswagen. A few United States (US) manufacturers produce 23% of the worlds vehicles while Japan is responsible for 21%. The tende ...

- 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 ...

- Fritz Haber Chemist And Patriot - 1,458 words
Fritz Haber - Chemist and Patriot The name Fritz Haber has long been associated with the well-known process of synthesizing ammonia from its elements. While primarily known for developing a process which ultimately relieved the world of dependence on Chilean ammonia, this twentieth century Nobel prize winner was also involved in the varying fortunes of Germany in World War I and in the rise to power of the Nazi regime. Haber was born on December 9, 1868 in Prussia. He was the son of a prosperous German chemical merchant and worked for his father after being educated in Berlin, Heidelberg, and Zurich. After a short time, Haber left his father's business and took up research in organic chemist ...

- Hydrogen - 1,153 words
Hydrogen Hydrogen in its liquid form has been used in space vehicles for years. Hydrogen has a high combustion energy per pound relative to any other fuel, meaning hydrogen is more efficient on a weight basis than fuels currently used in air or ground transportation. Hydrogen is the universes most abundant element. Most of that hydrogen though, is tied up in chemical bonds. Hydrogen can exist in either a gaseous form or a liquid form. Hydrogen is The liquid form is usually used for storage while the gaseous form is used as a heat transfer, and also as a cooling agent in nuclear power plants. The name hydrogen is Greek for water former. Hydrogen was once called "inflammable air" by a British ...

- 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 ...

- Space Exploration - 1,861 words
Space Exploration SPACE EXPLORATION: FROM THE PAST TO THE FUTURE Ever since the beginning of time, mankind has been fascinated with wonders of space. Before the mid-1900s, all mankind could do was gaze at the stars from Earth and wonder what it would be like to go into space. Man would look through telescopes and make theories on how the universe worked. During the mid-1900s, mankind finally was able to send a man into space and explore the wonders of space first hand. So why do humans explore space? Well, it is our fascination with the unknown. At first, all mankind did was look up and wonder how things became what they are now. We started to think that all celestial bodies revolved around ...

- 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 ...
