According to Dr. David Thompson, assistant professor in the Department of Chemistry at Memorial, long-term goal is to make fuel from sunlight, a field known artificial photosynthesis. The larger question revolves around whether a system can be designed to take captured solar energy and create molecules that can be utilized as fuels (Hester, 2007). The general idea, of course, is that the Petroleum Era will be replaced by the Hydrogen Era. Because hydrogen is so prevalent in the universe, it will require only the technological acumen to harness this most abundant element in order to produce a clean, unlimited, reliable, and endless supply of power. Enough scientists believe in this technology that in January 2003, President G.W. Bush announced a $720 million commitment towards the development of hydrogen fuel (www.hydrogenassociation.com). Modern society has the technology to change behaviors, or at least the vision to develop this alternate paradigm, but perhaps lacks the political will to do so. Change cannot happen with only one country, nor can it happen immediately. Instead, globalism must move beyond the tax...
The moral action in the contemporary world is to continue to work diligently to increase awareness of what fossil fuels do to our environment, to empower young people who will be the decision makers and inventors of the future, to continue to fight the slow political battles surrounding the issue of sustainability, and to encourage, wherever possible, the increased push towards hydrogen power.
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 seeking to make a fundamental change in the way they transport themselves will likely need a great deal of information, some of which may provide greater clarity while others may provide confusion and resort in them seeking out another alternative product. The consumer may then look for information that will support their inquiry into a commitment to a Hydrogen Fuel Cell Vehicle as opposed to one of many
Instead, loss of the fuel results in entropy, a concern of the second law of thermodynamics and this helps prove the impracticality of this fuel. Combine this with the size of the fuel tank necessary to power a car for many hundreds of miles, and hydrogen begins to look far worse as a real alternative to fuel conservation and replacing fossil fuels. Hydrogen seems like a good idea, and there
This is frequently referred to as entropy. 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
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
Alternative Fuel cars The best way that we can approach this complex subject is by differentiating the different types of fuels that the cars use since each fuel requires a different type of car and each fuel, accordingly, has its particular advantages and disadvantage. Biodiesel cars- Biodiesal vehicles combine petroleum gasoline with vegetable oils. Their benefits lie in the fact that these fuels produce fewer carbon emissions and reduced harmful particulates than
