There is a balloon the shape and size of a beach ball. A string keeps it tethered to the ground. Someone in a white lab coat stands about eight feet away with a rod about as long with a small flame on the end. They put on a protective headset and put the flame in contact with the floating balloon. Not even a second later the balloon violently explodes in a large fireball and a loud bang. All that remains of the balloon is the string that held it down and invisible molecules of water vapor now floating through the room. With the continuing buzz on the issue of global warming and the general rise of cost of fossil fuels alternatives have been explored. One of these is hydrogen power in the form of the hydrogen fuel cell. This source of power is unique because the only direct byproduct of it is water. With hydrogen power there are several ideas that need to be understood to determine if hydrogen power can significantly reduce or replace fossil fuels in homes and cars. First, how hydrogen is able to produce power as well as what a fuel cell is and how it works. Second, there are two primary ways to produce hydrogen, the electrolysis of water as well as from methane each with differing economic and carbon costs. Third, there needs to be an infrastructure to deliver hydrogen to the consumer, with its own cost. Fourth, with the rising prominence of hybrid-electric and pure electric vehicles and their advantages, hydrogen fuel cell technology has its own strengths over those alternatives. Fifth, the development of safety regulations around the transportation and storage of hydrogen. Sixth, past, present and future real world applications of fuel cell cars showing promise of a tomorrow with greater acceptance and availability of these veh... ... middle of paper ... ... sees strong consumer interest on its fuel cell microsite.” Just- Auto.com 5 (Jan. 2014).

It’s seldom that a movie is ever as good as the book, but after reading Water for Elephants by Sara Gruen, and seeing the film, I’d say they came pretty close. The book was filled with love, action, drama and the circus from the first page to the last. Of course, the movie couldn't possibly include all of the vivid descriptions and every little detail that the book does, or else it’d be seven hours long. But what I enjoyed about the movie was that it picked up on a lot of the great history of circuses in the 1930’s and truly captured the personalities of the characters that Sara Gruen wrote about in the book.
It is common for human beings, as a race, to fall into the comforts of routine – living each day similar to days before and days to come. Unfortunately, it is often too late before one even realizes that they have fallen into this mundane way of living in which each day is completed rather than lived, as explained by David Foster Wallace in “This Is Water”. This commencement speech warned graduating students of the dangers of submitting to our “default settings” of unconscious decisions and beliefs (Wallace 234). However, this dangerous way of living is no new disability of today’s human race. Socrates warned the people of his time: “A life unaware is a life not worth living” and who is to say he wasn’t completely right? A topic of long debate also includes the kind of influence that consciously-controlled thoughts can have on the physical body. A year after Wallace’s speech, neurobiologist Helen Pilcher, published “The New Witch Doctor: How Belief Can Kill”, which explains the influence of the mind and individual beliefs on the quality of one’s life. Together, both authors illustrate how detrimental a life lived unaware of one’s own thoughts and beliefs can be on the body and spirit. And though it is easy to live by
In Water for Elephants, the story is told through Jacob Jankowski at two different parts in his life: twenty-three year old Jacob who is out there exploring the world and, ninety-three year old Jacob who feels like he is wasting away his life in a nursing home. Water for Elephants is Gruen’s third book, it became one of the New York Times best sellers, it’s also available in forty-four different languages and it’s now a motion picture (Sara Gruen). Throughout the novel the reader is brought through both Jacob’s happy memories and ones that he wishes he could forget which shows its impact on the reader, a sense of catharsis and its social significance.
According to the quote, effects of the rising of the water were transportaion, food, and water. Transportaion for Mesopotamia was cruical because they (tribes and communitites) were often nomadic because the availability for food and water was limited. During this time period, food usually consisted of animals which included food such as meat and crops and the Nile River help supplied food and water.
On the other hand, hydrogen has a very limited infrastructure which is considered as a point on the negative side, or you can say one of hydrogen’s cons. And as Kukreja argues about the pros and cons of hydrogen energy; he mentions that “Hydrogen is also hard to move around. Whereas oil can be sent through pipelines, and coal can be carried in the back of dump trucks, super-light hydrogen is hard to transport in a reasonable fashion. It is very expensive to move anything more than small amounts of it, making it impractical for most functions.” [Kukreja] What he said makes sense. Hydrogen is some sort of gas. It’s not a liquid, or solid which can be physically carried in a way or another. Kukreja also mentions that one of the hydrogen energy cons is that it is “Not easy to replace existing infrastructure” [Kukreja] In a common sense, that is logically true. But in reality, if we felt into a problem that is related to global warming. Then the globe would regret building those gasoline stations. Even though it is hard to replace existing infrastructure, it is also necessary to get rid of those infrastructure even if we didn’t have a replacement. But in our position, we actually have a replacement which is hydrogen energy and hydrogen fuel

In the documentary, Blue Gold: World Water Wars, it follows several people and countries world-wide in their fight for fresh water. The film exposes giant corporations as they bully poorer developing countries to privatize their own supply of fresh water. As a result of the privatization, corporations make a hefty profit while the developing countries remain poor. Blue Gold: World Water Wars also highlights the fact that Wall Street investors are going after the desalination process and mass water export schemes. This documentary also shows how people in more developed nations are treating the water with much disregard, and not taking care of our finite supply. We are polluting, damming, and simply wasting our restricted supply of fresh water at an alarming speed. The movie also recognizes that our quick overdevelopment of housing and agriculture puts a large strain on our water supply and it results in desertification throughout the entire earth. The film shows how people in more industrialized nations typically take water for granted, while others in less industrialized nations have to fight for every drop.
A revolutionary environmental impact to pollution is provided by electric cars which produce zero emissions and provide a replenishable fuel resource. Toxic emissions into our earth’s environment would be reduced immediately as gas powered, pollution emitting vehicles are replaced with non-polluting, battery powered vehicles. Not only will pollution be reduced, but the means that power these vehicles are a renewable resource. Electricity can now be created by environmentally safer means, such as hydro-electric dams, wind farms, and various types of power plants proving a sound resource. With a safer, less polluting, renewabl...
In the future the global car market is full of potential. There are currently 44 million vehicles and by the year 2002 experts estimate that number will grow to 64 million. That growth is not expected to be in the US, rather in countries such as: China, India, The Pacific Rim, South Africa, and South America. In America, a current trend is for the neighborhood car dealer to be purchased by a large manufacturer, such as GM, so cars can be sold through retail outlets. Other future endeavors include low emission cars, which are expected to provide expansions in sales. Some major automakers are investing in fuel cells, devices that convert liquid hydrogen into elec...
Let it first be understood the underlying principles of hydrogen power production in a fuel cell. There exist many hydrogen fuel cells being developed by multiple companies worldwide; however, the fuel cell showing the most promise as a future source of alternative power is the Polymer Exchange Membrane Fuel Cell (PEMFC) and is widely regarded as a possible replacement for diesel and petroleum cars (http://www.fctec.com/fctec_types_pem...
Recent years have shown an increasingly large need for a practical renewable energy source for such reasons as diminishing fossil fuels and increases in greenhouse gasses. Hydrogen appears to be a way out of this gasoline-dug hole, or at least, a way out in the future. Hydrogen fuel cell cars are being engineered as we speak as the technologies to refuel them cleanly are being proposed. Unfortunately, most of the technologies associated with hydrogen are still in the prototype/pre-production stages and require better enhancements before becoming mainstream. This paper assesses the practicality of hydrogen power in cars both now and in the future while explicating the actual process of how a hydrogen fuel cell works.
Many people around the world need water. Around 780 million people are unable to get clean water (One Billion Affected). People who do have access to clean water in their homes, have to pay a fee. The people who struggle to live obviously do not have enough money to buy water. People who are unable to have clean water have a good chance of dying either from disease or from dehydration. At least 3.4 million people die a year from water problems such as sanitation (One Billion Affected).
The power of nature is all around us and can be found almost anywhere. One is able to study nature through experiencing it firsthand, looking at a picture, watching a movie, or even reading a familiar children’s story. I believe that by learning more about nature we can grow closer to God. Emerson states, “Nature is so pervaded in human life, that there is something of humanity in all, and in every particular” (Emerson 508). Like Emerson, I believe that humanity and nature were created by God and we can learn more about the Spirit of God by studying nature. I also see that nature has the power to influence our emotions and actions. I see evidence of this through various landscapes such as the desert, the beach, the mountains and the jungle. I thought about the vastness of the desert during a recent trip to the desert with my class. I think about nature and my love for it when I am scanning through my photo album and see pictures that capture me enjoying the mountains of Utah. When I watched the movie The Beach I was struck out how nature, specifically the beautiful beaches of Thailand, influenced the actions of every character in the movie. Of course it is hard to read a legendary story such as “Jungle Book” and not see what a powerful effect nature and its’ animals can have over humans.
Hydrogen would be one of the easiest sources of renewable energy to incorporate into our current energy infrastructure. Since hydrogen is a gas of normal temperature, it is possible to have it be used as a fuel in vehicles similar to current ones. For example, Hydrogen could be introduced into the vehicle as a gas, stored...
