In the past decade there has been a great deal of worrying about what will happen when the world’s oil supply becomes depleted. The main reason for concern is that almost all of the automobiles in use now require an oil based gasoline to run their internal-combustion engines. In the next few decades it is predicted that all of the world’s oil will have already been mined, and combustion engines will be unable to function. For this reason many companies such as Ford, Mercedes-Benz, Chrysler, Toyota, BMW, and others have started to create engines that do not require oil based gasoline. Such engines include the battery-powered engine and the hydrogen-powered engine. These engines require different fuels and all have their own good and bad qualities. This essay will describe these engines and how they work.

The battery-powered engine is run using solely battery power. The battery-powered engine, along with all the other engines mentioned in this essay pollute much less than the combustion engine. The battery-powered engine is more efficient than the combustion engine for a variety of reasons. One reason includes how the electric motor is directly connected to the wheels; this lets the vehicle consume no energy while the car is at rest or coasting. Another way the battery engine is more efficient than the combustion engine is the fact that the battery engine converts more than 90 percent of the storage cell energy into driving force, while the combustion engine converts only a m...

  • Power of the Branches

    1126 Words  | 3 Pages

    The Legislative Branch is Congress, which has just two branches - the House of Representatives and the Senate. To understand the power held by the Legislative Branch, we should refer to the Constitution itself. Per Section 8 of Article I, Congress may only act within the powers granted to them explicitly in the Constitution, these are called enumerated powers. But this doesn’t mean the powers granted to them were diminutive. The entire legislative power was constitutionally delegated to Congress. The House and Senate serve, for the most part, to work together (though not necessarily in harmony) on passing laws, and both House and Senate must approve all bills. The framers began with the forming Article I: The Legislative Article for a simple reason; law making is an extremely important function for our government. I believe they dug their heels in here first because they intended for it to be the longest, most thorough article in the Constitution, and every word truthfully serves a divine purpose of laying out the structure of how our Legislative Branch should run. With a mere 2,...

  • Discretion in Police Duties

    1036 Words  | 3 Pages

    Discretion is often one of the most critical aspects of a police officer’s daily duties. In the past, police discretion was considered taboo until 1956 when a study conducted by the American Bar Foundation discovered that there is nothing illegal or improper about discretion, and that it is in fact of practice (“The Role of Discretion in Police Work,” 2012). Before discretion was officially accepted as practice, police officers would not admit to be involved in police discretion. The basic definition of discretion is the use of personal choices when carrying out typical police job duties. For example, a police officer may decide to arrest one suspect for police interference, but will let another suspect go home, for the exact offense. When using discretion, however...

  • Police Force and Discretion

    758 Words  | 2 Pages

    The degree of force that officers use is heavily influenced by police discretion in real-world situations rather than espoused by a certain agenda. Discretion can be classified into four different categories where administrators, the community, and the individual police officer exercise differing degrees of influence in decision-making. What is needed to help officer discretion is a central ethos that will guide discretion when all other rules fail to help.

  • Police Discretion and the Use of Force

    2111 Words  | 5 Pages

    Discretion is defined as the authority to make a decision between two or more choices (Pollock, 2010). More specifically, it is defined as “the capacity to identify and to document criminal and noncriminal events” (Boivin & Cordeau, 2011). Every police officer has a great deal of discretion concerning when to use their authority, power, persuasion, or force. Depending on how an officer sees their duty to society will determine an officer’s discretion. Discretion leads to selective enforcement practices and may result in discrimination against certain groups of people or select individuals (Young, 2011). Most police officer discretion is exercised in situations with individuals (Sherman, 1984).

  • Gas Cars vs Electric Cars

    1667 Words  | 4 Pages

    I bet you didn't know that the first cars made were all mostly electric. But as time passed gas powered cars became more popular through the years. There were few if any electric cars available as timed moved on. Everyone believed that gas powered vehicles were more convenient than the electric powered ones. I believe that gas powered vehicles are better because gas powered cars have more function ability. The range that electric vehicles have is poor compared to gas vehicles. Electric vehicles don't function very well when the weather is cold. You'll need to charge your car pretty much every night. You are only going to be able to go 80 mph. If you go up a big hill your range goes down. electric vehicles (rather ev's) do pollute but they don't pollute the same way that gas cars pollute.

  • Analysis Of The Movie Jack And Jill

    815 Words  | 2 Pages

    The film Jack and Jill primary ideas throughout the film evolves around the conflicts and differences between both siblings. The conflict between siblings was the primary reason why I did not find this film funny or saw any humor to it. Firstly, the film’s cheap humor is portrayed through Jill where the standards of a female persona were lowered. This is evident as Jill is often needy, helpless, likes to be the center of attention, and has no filter in which she speaks her mind out. I did not agree to this, as this is not an ideal or pleasant image to give to a woman. In addition, she shows her neediness and helplessness as she longs spending sometime with her twin brother; however, she over exaggerates things and wants to do things with her brother that they use to do when they were kids. I personally think that it is ok to hug your siblings and show them some affection however; Jill takes this affection to another level and wants to cuddle in bed with her twin brother like old times. Cuddling while being adults in their forty’s is just a creepy imagine to see and not funny at all. Moreover, Jill has no filter when she talks

    The film can be seen to appeal for interest emotionally, the way of pathos appeals but then it occasionally showcases scenes that engages us or simply throw us into disbelief and maybe even irritate us. Multiple scenes in the documentary had provided some laughable moments or few chuckles that would help relax the tense atmosphere of the viewers, despite the serious matter in discussion. The best aspect of film is truly the disbelief factor; refer to the textbook long list preexisting condition that denied health insurance to many applicants, basically, the need of a master’s degree to apply for health insurance. That and considering the emotional scenes, makes Sicko a much more impressive and captivating documentary than that of its
