Internal combustion engine Essay Example for Free

Internal combustion engine Essay An electric car is a vehicle which is driven by electric engines. The engines use electrical energy which is usually stored in batteries. Electric car is a variation of electric vehicle (EV). EV speaks of any vehicles which are propelled by electric engines. â€Å"Electric car† is a general term for high-speed vehicles which are powered by electricity. In the United States, low-speed vehicles which are powered by electricity are known as neighbourhood electric vehicles (NEVs), and as electric motorised quadricycles in Europe. Electric cars which are powered by different energy sources are also referred to by different names: if they are powered by sunlight, they are called solar cars. If they are powered by gasoline generators, they are called hybrid cars. The term â€Å"electric car† is usually referring to battery electric vehicles (BEVs), which are powered by on-board battery packs. Advantages of Electric Cars The first thing which comes to people’s mind when we talk about the advantages of electric cars is usually on pollution. Electric cars do not cause pollution related to internal combustion engines. The electricity used to recharge electric cars obviously has to come from somewhere, and most of the electricity is produced by burning fossil fuels. Yes, this causes pollution for sure, but there are also other methods to produce electricity. Hydropower and nuclear plants have helped in cutting the carbon emissions. Despite all the electricity production, the carbon emissions produced by electric cars is said to be half of what gas-powered cars produce. Another major advantage is you do not need gas anymore. In a year, an average American spends around $2,000 to $4,000 on gas only. Although electricity is not free, the fact that you do not have to pay so much for gas is relieving. The third advantage which needs to be stressed on is the batteries. Though you cannot drive many hundred miles with an electric car, you can still travel a rather long distance. An electric car can travel up to 100 miles on full battery. The distance it can provide is perfect for you to travel from your home to your workplace, and vice versa. Also the batteries recycle well. Almost 100 per cent of the batteries can be recycled; this helps preventing it from causing disposal problems. Electric cars are more efficient compared to gas-powered cars, in terms of energy and maintenance. Electric engines use 75 per cent of the energy from the batteries to run the wheels, while internal combustion engines only use about 20 per cent of the energy from fuel. Electrical engines also require less maintenance compared to internal combustion engines. You no longer need oil to lubricate the engine. The brakes would not wear off as quickly as gas-powered cars. You do not need belts in the engines, which will wear out due to overuse, in electric cars. Disadvantages of Electric Cars The major disadvantage of an electric car is the batteries. Electric car batteries are not cheap. They can cost around $5,000, and the better the batteries, the more expensive they are. Not only are they expensive, but you will also need to change them more than once, as the batteries have a limited lifetime. The time required for recharging the batteries is also very lengthy. To fully charge the batteries, you need 4 to 8 hours. This is a very serious disadvantage, as most people need to have their cars ready 24/7. With gas-powered cars, you just need a few minutes to fully refill the tank. Still on the batteries, another disadvantageous factor is their size and weight. Batteries used for electric cars need to be linked together into arrays, which form battery packs. Battery packs are bulky and heavy. They take up a significant amount of the vehicle space. Given the heavy weight, they battery packs can reduce the distance of how far the car can travel. Another disadvantage is the silence of electric cars. Yes, it can be soothing for some people, but it can also be dangerous for others. People usually listen to the sound of the revving engines when cars are coming up behind or beside them. When it is silent, they might not notice the cars and they can end up in an accident. Bibliography Bhat, N. (n. d. ). The Future: Our Planet in 2050 | Electric Cars.

Government Providing for the Poor :: American America History

Government Providing for the Poor "In the Middle Ages men were united by custom and prescription into associations, ranks, guilds, and communities of various kinds. These ties endured as long as life lasted. Consequently, society was dependant, throughout all its details, on status, and the tie, or bond, was sentimental. In out modern state, and in the United States more than anywhere else, the social structure is based on contract, and status is of the least importance." This quote by William Graham Sumner in his 1883 speech "What Social Classes Owe to Each Other" illustrates my main focus of this week's proposed question, "Does American Government have an obligation to provide for the poor?" Sumner supports that the American Government does not have an obligation to provide for the poor because in America, all people have the opportunity to work hard and bring themselves out of poverty, where in Europe and their other native lands, people were trapped in a caste system in which they could not escape. In America, th ere was is a defined class system in which those living in the society were confined and hard work, followed by success, is a luxury offered in America. By living in a free state like America, Sumner says, its citizens live equally among one another in a society based on a contract, which allows the most leeway for individual developments and successes. Every man must fend for himself in this society that allows for personal establishment. Sumner also says, "It follows, however, that one man, in a free state, cannot claim help from, and cannot be charged to give help to, another." He directly says that it cannot be imposed upon the American Government that hard-working tax-paying citizens should have to financially assist the plight of the poor. The Populist Party Platform of 1892 says in its second declaration that "Wealth belongs to him that creates it...If any will not work, neither shall he eat." The Populist Party realized that men were fully entitled to their earned keep and s hould they not work, they should not be provided for by the government, especially not by collected tax money. Sumner goes on to say that those who rely on the support of the government become so dependent that welfare inevitably produces lazy citizens. He says, "The man who has nothing to raise himself above poverty finds that the social doctors flock about him, bringing the capital which they have collected from the other class, and promising him the aid of the State to give him what the other had to work for.

The Daily Telegraph

For my coursework piece, I decided to a newspaper editorial which had been published online. The piece was written as if it had been published in The Daily Telegraph, a right-wing middle class newspaper. I chose to do the piece because I am interested in current affairs and newspapers, and I am a very opinionated person. I thought that a newspaper column would be a good place to share my opinion on the topical story of waterboarding. For my style model, I went onto the Telegraph's website and found a newspaper column by Boris Johnson, the Conservative Mayor of London. As a Conservative, his column had a slight anti-Labour bias, although it was very subtle and often humorous. I attempted to replicate this when I mentioned that waterboarding is classed as an ‘enhanced interrogation technique' and quickly quipped that that was â€Å"more spin in one phrase than Alaistair Campbell managed in an entire dossier† – a reference to the controversial September Dossier which ‘sexed up' claims that Iraq had Weapons of Mass Destruction. From that quote, we can see some of the writer's persona, seeing immediately that they are critical of the Iraq War, despite later making it clear he is a Conservative (â€Å"thankfully, I'm a son of Thatcher†). We can see more of the writer's persona throughout, by writing with a high register, we see that they are quite sophisticated and maybe slightly arrogant. The piece starts with a graphic description of what would happen to a victim of waterboarding, but as it features direct address, it makes the reader feel like that it is happening to them – â€Å"you have a bag over your head†, â€Å"you are shackled†, â€Å"you feel like you are drowning†. After each description of the torture, the actual theme is introduced. Originally, my piece was going to follow a structure by which each waterboarding scenario would be followed by the writer's opinion, but before my final draft I decided that this actually distracted from the main point of the article, so I decided not to continue with this idea. My main argument starts in the paragraph beginning â€Å"Let's be clear on this matter†. That sentence of â€Å"let us be clear† makes it seem like I know what I am talking about and that I am being completely honest. My arguments are further bolstered by listing officials who have disagreed with George Bush's claims, such as the Director of Public Prosecutions and the United Nations High Commissioner on Human Rights. The summing up of my arguments begins with George Bush's original comment which sparked this news story. The language used in the ensuing four paragraphs is emotive, and reads almost as if it were a speech. It really attempts to put the reader on the side of writer, and make them believe that Bush was completely out of order. The story was published on the week on which Remembrance Day fell, so I as the writer incorporated this to try and shock the reader and make them nod sagely in agreement with me when I state that the reason we entered the Word Wars in the first place was to â€Å"fight for our lives and our rights†, and then contrasting that by saying that Bush â€Å"a former leader of the free world† can say that â€Å"freedom and democracy†¦ can go to pot if it might save some lives†. The following one clause sentences have a short and long lasting impact by simply refuting Bush's claims. I enjoyed writing this piece, as it gave me a chance to put my opinions forward. Having my peers read my work and give feedback was a good experience that I enjoyed, as I like people correcting me and reading my work.
