Hydrogen: the Fuel of the Future?
The Problem:
For years, United States citizens have been using natural gases and oils to power their cars. While doing so we have also been polluting our environment, making ourselves dependant on other regions of the world, and depleting our oil reserves. Rory Sporrows of “Geographical” wrote, “The car is responsible for combusting eight million barrels of oil every day, contributing to nearly a quarter of total global greenhouse emissions and causing major increases in bronchial diseases like asthma and emphysema.” (2001) Oil is not a renewable resource. One day it will run out. The graph to the left depicts that in these times in which we should be conserving what we have; we are doing exactly the opposite. Although the United States makes up only five percent of the worlds population, it consumes more than twenty-six percent of the world’s oil. And if we let our situation get to the point that we run out of oil, our average internal combustion, gasoline engines will no longer work. We will be forced to turn to alternative means of power.
Hydrogen Fuel Cells:
There are many alternative means of power that have been suggested: solar, wind, hydro, and hydrogen fuel cells to name a few of the more popular ideas. The focus of this research paper is hydrogen fuel cells.
For hydrogen fuel cells to work the process requires pure hydrogen. However, hydrogen is the most abundant element in the universe, pure hydrogen doesn’t occur naturally anywhere on earth. We have to refine it ourselves.
Water can be split into separate parts through a process called reverse electrolysis. Water or H2O, seen in the diagram to the right, can be decompressed into free-floating hydrogen (H) at...

The tragic tale of the Salem Witch Trials in Massachusetts was re-written by Arthur Miller in the form of the play “The Crucible”. The trials have been studied to figure out what really happened, but no one will ever know since it happened decades ago. The play is the closest reenactment we have to help us see how people could have reacted to life. “The Crucible” shows how using others as a cushion to keep from being punished can go extremely bad. Amidst all the chaos a man by the name Reverend John Hale came to help but ended up with making it a huge amount worse.
Arthur Miller’s The Crucible, is about mass hysteria of witches being in the town of Salem, Massachusetts. An educated man named Revered Hale arrived in the town with his exclusive knowledge of witches to help the town eliminate the presence of the Devil. He became a member of the court and aided in putting innocent people in jail or hung. As Hale started to see the consequences of his actions, he struggled with fixing his mistakes. The change in his perspective of the witch trials caused his overall personality and attitude to change as well. Hale’s dialogue, stage directions, and other people’s perceptions of him reveal a man motivated by good intentions; furthermore, his mission to help Salem destroyed evil in the beginning and his attempts
The test that Reverend John Hale faces is whether he can change his character early enough to redeem himself for the lives he has caused to be lost. He is the character that shows the most significant transformation overall. When he first comes to Salem, he is eager to find witchcraft and is honored that his scholastic skills are necessary. He feels that as an exorcist, it is his duty to help pe...
Because he is forced to accept that his beliefs have been messed with and realizes that he has sent people to their deaths, he loses faith in the law and questions his faith in God. Arthur Miller put many events into the story and tells about Hale’s mindset. In the middle of Act I, Hale comes and what he is called by the townspeople “The truth seeker”. Hale is called upon to determine what sort of witchcraft is going on. Hale arrives admired by the people who wants him to calm this nonsense of witchcraft down. He understands he being led toward the conclusion of witchcraft by the town’s wrong doings. He also begins to see a weakness in the position of the townspeople of Salem and tries to not let common things be the support for his
Throughout The Crucible, Reverend Hale is a faithful and intelligent minister. He comes to Salem as the spiritual doctor to respond to the rumors of witchcraft, which have been flying in Salem after the strange illness of Reverend Parris’s daughter, Betty Williams. Hale never declares witchcraft, but he relies on people’s evidence of it because of the large amount of evidence. As the play goes on, Hale’s intelligence leads him to other sources of hysteria and accusations. The change in the character of Reverend Hale is noticeable throughout the play. In The Crucible by Arthur Miller, Reverend Hale grows from a confident, authoritative figure, trying to end witchcraft in Salem, to a regretful, fair character who wants to end injustice and save innocent lives.
Brutus is considered an honorable man by all those who live in Rome. He is a close friend of Caesar, husband of Portia, and is also a Senator. Brutus is drawn into killing Caesar by Cassius, who was jealous of Caesar's degree of power. Brutus was pulled into the scheme by letters brought to his house by Decius to make him think that the people of Rome wanted him to replace Caesar. Brutus also feels that Caesar is being given too much power and will destroy Rome's democracy. Brutus' reason for killing Caesar is to benefit Rome, he proves this when he states"If then that friend demand why Brutus rose against Caesar, this is my answer: not that I loved Caesar less, but that I loved Rome more." After losing to Mark Antony and Octavious, Brutus runs onto his own sword. He sticks to his beliefs, not altering them for others.

In The Crucible by Arthur Miller, Reverend John Hale’s role in the witch trials changed from a confident and passionate proponent to a guilty and despairing dissenter. He entered the play with an eager air about him, and he was keen to use his expertise and knowledge in witchcraft and the Devil in order to dispel the evil witches who “trafficked with the Devil” (Miller 61) in the town of Salem. Furthermore, he was proud of the fact that he was called upon specifically to help out with Salem’s witch problem. However, toward the end of the play, he was “steeped in sorrow” (Miller 119) and “exhausted.” He realized too late that the accusations of the afflicted girls were just fabricated lies. Moreover, his mistake caused a countless number of innocent people to be thrown in jail and hanged. With this revelation clouding his mind and breaking his heart, he became an anguished man who regretted his actions that aided the conviction of numerous so-called witches. He fought against the witch trials after that, but his actions were inadequate. The witch trials still went on. Hale ended up being a character who opposed the witch trials, but instead of going against the court as aggressively as John Proctor, he begged the accused to confess in order to save their own lives. He believed that it was better to lie and live than deny and die.
Erik Erikson was an ego psychologists. He established one of the most widespread and dominant theories of human development. His theory was influenced by Sigmund Freud theory. Erikson 's theory centered on psychosocial development and Freud’s theory centered on psychosexual development. Erik Erikson 's theory of human psychosocial development is the best-known theory of personality. Like Sigmund Freud, Erikson thought that human personality matures in stages. Erikson 's theory outlines the effect of social experience across a person’s whole life.
Caius Cassius and Marcus Brutus are senators of Rome, who deliberate over Caesar’s use of power he now holds in the Republic. They fear that Caesar may decide to become the monarch. Cassius, a popular general himself, is envious, while Brutus has a more balanced opinion of the political situation. Cassius and his friends visit Brutus at nightfall to coax him of their views, and they plan Caesar’s assassination. Brutus is anxious but will not divulge this to his wife, Portia.
Native American Indians were human beings that lived off the land in North America. They had to of migrated from Siberia. In order to do that, they would have had to cross the Bering Land Bridge. A bridge existing during the ice age that connected today’s Alaska and Russia. Before Europeans reached North America, Natives had the prefect life, they had complete freedom. They lived in peace and harmony. Just like everyone today, the Natives had religion too.
While at camp Brutus and Cassius get into an argument leading to Cassuis saying he shall kill himself. After that in solved Brutus heads to bed. In the middle of the night he wakes up to the ghost of Julius. Caesar tells his old friend “Though shalt see me at Philippi.” Brutus is startled by this and isn’t sure what was meant by this. Will Caesar live again or is this some kind of omen. Brutus and his troops March to Philippi. After Cassuis dies, Brutus and his troops are winning, although Brutus don’t realize it. Brutus decides to take the cowards way out of this and kill himself, rather than be drug through the streets of Rome. Strato holds out his sword as Brutus runs about and kills himself.
According to the US Environmental Protection Agency, over half of the oil used in the USA is imported. Most of this imported oil is located in the middle east and is controlled by OPEC members. Subsequent oil price shocks and price manipulation by OPEC have cost our economy dearly—about $1.9 trillion from 2004 to 2008—and each major shock was followed by a recession (Reduce). We may never be able to fully eliminate our need to import oil, but we can reduce cartel market control and the economic impact of price shocks by reducing our demand (Reduce). One way we can reduce our reliance on oil is through investing in renewable energy. Solar power, wind power, and hydro power are all forms of energy which come from renewable resources. Unlike oil, solar, wind and hydro electric power is abundant and can be obtained locally.
It is unfortunate that within the past 100 years our worlds' economy has driven itself into a deep hole with the reliance on a "black gold" called oil. Since its discovery, it has been purified to produce many different forms of energy such as light, gasoline and more. Since technology has enabled mankind to discover more capable methods of transportation, mankind has exploited its power over nature and produced machines such as the combustion engine. In combustion engine's, oil explodes to move machinery, and emits a very toxic byproduct called CO2. Carbon is incredibly dangerous to the earth's atmosphere, and erodes huge holes in the ozone layer of our earth. This erosion causes global warming and climate change that is permanent and irreversible. The impact of global warming will not only ...
