In the route of energy transfer, some energy will disperse as heat. Entropy is a measure of disarray. The course of energy sustains order and life. Entropy is successful when organisms stop taking in energy and die (Laws of Thermodynamics, 2010).
Many experts feel that Hydrogen is the ideal fuel known to man at this time. It is a fuel source that has no chance of being depleted until the Sun stops producing it. There isn't much chance of the Sun stopping production either. The only result of hydrogen combustion is water. Because one of the ways hydrogen can be produced is by separating it from the oxygen atom in a water molecule, the process lends itself to recycling within a closed system. There are a few negatives that surround the use of Hydrogen. First, it is a very dangerous explosive. It is also very costly to produce and most procedures that are used to produce it today are not very efficient. When handled properly, hydrogen is perfectly safe (Hydrogen: The Never Ending Fuel Source, n.d.).
With the invention of more efficient means of production, the cost of manufacturing and storing hydrogen will decrease and it will become...
Fuel Cells in Green Engineering The energy tomorrow is beginning to be available today. Fuel cells, which just a very few years ago were a pipe dream, are becoming g a reality, and they are used in areas ranging from space exploration to toy motivation (Joy). The promise of the fuel cell can be seen in the fact that they use the most abundant source of energy on the planet, Hydrogen
People are typically inclined to think that a product becomes less expensive once it enters mass production. However, this is not the case with hydrogen powered cars, as it will still be expensive to produce the fuel and to make cars capable to run on it. Gasoline burning-vehicles are likely to be replaced with cars using alternative sources of energy in the near future, only that hydrogen is improbable
The study advocated a broader energy policy for automobiles, specifically one that allocated more money to the development of gas-electric hybrids. Hydrogen may be the fuel of the future, but it is a distant future, at least fifty years away (Stauffer par. 8-9). In the meantime, the development of proven technology will be of more benefit than hydrogen. The Myriad Issues with Hydrogen: Availability, Extraction, and Storage Are Just the
Different Fuel Cell Technologies U.S Department of Energy (2010) provides the description of different fuel cell technologies. The fuel cell technologies are differentiated according to their efficiency, operating temperatures, costs and application. The classifications are based on 6 major groups: Alkaline fuel cell (AFC), Phosphoric acid fuel cell (PAFC), Solid oxide fuel cell (SOFC), Molten carbonate fuel cell (MCFC), Proton exchange membrane fuel cell (PEMFC); Direct methanol fuel cell (DMFC). Alkaline fuel cell (AFC) The AFC generates electrical power
Fuel Cell Technology There are over 600 million motor vehicles in the world today. If present trends continue, the number of cars on Earth will double in the next 30 years." ("Cars Emit") As the demand for energy increase and resources, such as fossil fuel, decrease alternative must be sought. Of these alternatives, hydrogen fuel cell technology, in automotive applications, has significant benefits and is now technologically feasible. Given this knowledge,
Fossil Fuels & Their Impact on the Environment Impact of Fossil Fuels on Environment Fossil fuels are formed by anaerobic decomposition of organisms over a period of millions of years. When burnt, they produce significant amounts of energy per unit weight and cannot be reused to supply energy. They are thus nonrenewable resources. The applications of fossil fuels range from use in motor vehicles, trains and industries to household consumption in stoves
