Hybrid Electric Vehicles and Their Advantages
'The HEV [Hybrid Electric Vehicle] concept goes back to 1905. On November 23 of that year, American engineer H. Piper filed for a patent on a hybrid vehicle. Piper's design called for an electric motor to augment a gasoline engine'(1, pg 2) and thus, the HEV was born. Hybrid Electric Vehicles, otherwise known as HEVs are vehicles that 'combine the internal combustion engine of a conventional vehicle with the battery and electric motor of an electric vehicle'(2).
In this day and age car manufactures are trying to out-compete one another in terms of car features and sales. Technology has come a long way since 1905 but the principle is still the same: to produce hybrid vehicles that not only can compete with standard vehicles in terms of price and available features, but that also offer better mileage and less pollution. One may understand why hybrid vehicles are a good choice, but one may not understand why more auto manufacturers have turned to hybrids instead of electric vehicles. 'HEVs do not share an electric vehicle's main drawback: limited range between chargings. The few thousand electric vehicles on the roads in the U.S' can travel only about 80 miles before their batteries need recharging, which can take anywhere from three to eight hours'(1, pg1). For those who do not wish to be constrained by having to charge up batteries and worry about mileage, HEVs are the next logical choice.
There are two different types of hybrid vehicles: parallel and designated series. The following is a good description of each :

...ent as well. Hybrid vehicles emit significantly less pollutants than do standard cars and trucks and their fuel efficiency is also a positive aspect that can attract consumers who are interested in saving money. As technology advances and hybrid technologies becomes more efficient it seems that the HEV ?could be- - and in fact should be - - the car of the near future?(1).

The California Gold Rush is one of the most interesting events in American, as well as, California History. The event gathered many in search of quick riches and opportunity globally. The opportunity of mining stretched American east coast influence to the West coast. Also bringing many from South America, Canada, and the Pacific Islands. Andrew Isenberg wrote, Mining in California: An Ecological History, which gives a detailed account of the California Gold rush and how it affected the California economy as well as California social environment during the 19th century. Isenberg conveys his argument in two parts throughout the book the economic side as well as the social side.
The California Gold Rush in 1849 was the catalyst event for the state that earned them a spot in the U.S. union in 1850. This was not the first gold rush in North America; however, it was one of the most important gold rush events. The story of how the gold was discovered and the stories of the 49ers are well known. Men leaving their families in the East and heading West in hopes of striking it rich are the stories that most of us heard about when we learn about the California Gold Rush. Professors and scholars over the last two decades from various fields of study have taken a deeper look into the Gold Rush phenomena. When California joined the Union in 1850 it helped the U.S. expand westward just as most Americans had intended to do. The event of the Gold Rush can be viewed as important because it led to a national railroad. It also provided the correct circumstances for successful entrepreneurship, capitalism, and the development modern industrialization. The event also had a major influence on agriculture, economics, and politics.
According to the article “Gold Rushes and Silver Strikes,” the Gold Rush changed the landscape in California and the population started to increase each year. Basically more people wanted to become wealthy and their settlement in California changed the landscape and population increased because more and more people began immigrating. According to the article “California Gold Rush (1848-1858),” it changed California democratically and it became one of the most ethnically diverse states. Also, taxes were proposed so people would stop mining. As stated before, California became one of the most diverse because of migration. California proposed the a tax on mining because too many people were immigrating there. According to the article “The Gold Rush of 1849,” independence into wage labor, produced new mining techniques. An example of a new technique is hydraulic mining which brought enormous profits, however, it destroyed regional
There have been many discoveries that have shaped our nation as a whole. Discoveries have allowed our country to thrive and become one of the most powerful nations in the world. When we look back at our nation's rich history, it is clear to see that there was one discovery in particular that had a vast impact on the United States; the discovery was gold in California. It was in this vastly unoccupied territory that the American dream was forever changed and California emerged as a powerful state busting at the seams. The California Gold Rush shaped California into the state that it is today. California is defined by its promise of entrepreneurial success and its acceptance and encouragement of obtaining the American Dream.
"Gold! Gold! Gold from the American River!" said Samuel Brannan, as he ran through the streets of San Francisco waving a bottle of gold dust in the air that he purchased from John Sutter’s Fort. The encounter of gold nuggets in the Sacramento Valley in early 1848 triggered one of the most crucial occurrences to influence American history during the beginning of the 19th century, the Gold Rush. The Gold Rush of 1849 (1848–1855), also known as the California Gold Rush, was one of the most captivating happenings during westward expansion. The Gold Rush of 1849 is also a fundamental event that not only impacted California but the United States as a whole and individuals from throughout the world. Thus, despite laborious toilers and their small chance to improve their lifestyle, California is defined by its promise of industrial success and its acceptance and inspiration of obtaining the American Dream.

“Animal Entertainment” refers to any animals used to act, perform, or fight for the enjoyment of humans. zoos, circuses, and bullfighting are all examples of animals used for entertainment. While many applaud these firms for putting on a spectacular show, many others argue that the animals are treated unfair. All of these animals are taken out of their natural environment and forced to perform acts not typically in their behavioral range. If one pays close attention at the circus, for example, it is visible how these animals are treated. Trainers threaten tigers with a whip and often hit elephants with metal on their legs. These techniques are inhumane and best explain why animals should not be used for entertainment. The use of animals for entertainment is a form of animal abuse because of the way the
California saw many changes very fast. Most of these play part in shaping it into what it is today. From Hollywood to San Francisco, today’s lifestyles in California have roots in the Gold Rush. Because the failure rate was so high, it became common to come out to California lookin...
Since the release of this first mass-produced of the hybrid vehicles the government has been doing a lot of things possible to be involved and also to regulate the purchasing’s of HEVs and PHEVs. Today, the President Obama has created a New Energy For America to plan for changes to its way the United States uses energy. The plan does include a section on the hybrid vehicles and plug-in hybrids. Soon the tax credits will be ended for its regular hybrid electrics vehicles. Now it is known, due to the rapid rate of the HEV sales the government has also withdrawn its tax rebates on HEV models, by giving exclusive tax cuts on EV and PHEV models, which based on its total electric charge that the battery pack can hold. Since then, HEV cars were popular among environmentally conscious drivers.
Next is being bullied physically, being bullied physically is more often heard about in our world today people being bullied at school and getting beat up for reasons such as they are different or do not act the same way others think they should. Other people in society are picked on physically because of their size and other students know these children cannot stand up for themselves. Piggy exper...
The future American commuter will undoubtedly have to transition from the use of fossil fuels to new alternatives due to the diminishing availability of the nation’s oil resources. How will America respond to this upcoming issue? It is difficult to predict which alternative fuel source America will ultimately choose, but with the premier of Nissan’s electric powered Leaf and other companies; such as Tesla Motors and Chevy, with their electric cars ready for market, the electric car may be winning the race to become the new standard for the gasoline alternative. Electric cars resolve long standing environmental issues, but it will need to maneuver around many roadblocks to become a marketable consideration for the general public. The cost of electric cars, currently on the market, makes them an impractical purchase for the average consumer. If cost is not the growing concern in today’s economy which prevents the consumer from considering this option; they may deny the technological advance due to battery storage capabilities and the inadequate infrastructure in place to refuel and provide for them.
Environmental concerns have been raised from time to time because of the dependency on the gasoline-fueled engine as the chief auto powertrain technology. This has resulted in exposing many automobile users to unpredictable prices of fuel. These issues were, however, the reason for the inception of Tesla Motors so as to bring into existence another set of automotive which serves the similar purpose; but uses another form of energy that being electricity to drive them instead of the disadvantageous gasoline-powered engine. This invention was influenced by a number of factors in terms of their planning and performance (Hunger, 2010).
The world is constantly trying to invent and find new forms of entertainment. This being said, people often find pleasure in watching animals. When thinking about how animals are used in the entertainment industry, it seems that in most cases they are being mistreated. Owners of such animals that are neglected lack the care and knowledge to provide for them. This is a social issue because not only do we use animals for our own enjoyment, but we uproot them from their natural habitats and take them away from their families.
Today, people use their own personal vehicles to travel more than ever before. Personal transportation is no longer considered a luxury; it is now considered a necessity. The number of cars in the United States has been growing steadily since the 1970s. The number of miles traveled by cars has risen nearly 150 percent, yet the United States population has only grown roughly 40 percent during that time (hybridcars.com, Driving Trends). Although it may seem like we are advancing into the future, in reality, we are moving backwards from the effects these vehicles have on our bodies and the environment. The pollution produced by these vehicles has brought us to the day where we must find other modes of transportation that cause less harm to the world in which we live. Advances in technology have developed hybrid vehicles to try and slow down the amount of pollution. Driving a hybrid vehicle, instead of a conventional gas powered vehicle, can reduce the amount of pollution that affects our lives and the environment around us.
There is no doubt that electric cars are the most appealing from of transportation in the world. They provide two of the most important key points of good transportation: reliable and efficient. They are reliable due to their simplicity of their power trains and the advancement of technology they have. They are efficient because they don't use any gasoline and because their motors can pass the zero-emission standard. Even though they may seem like a boring form of transportation, they offer good features that help keep the Earth's air clean and they help reduce pollution.
