Intro Sample...


The electric motor on a hybrid car is very sophisticated. Advanced electronics allow it to act as a motor as well as a generator. For example, when it needs to, it can draw energy from the batteries to accelerate the car. But acting as a generator, it can slow the car down and return energy to the batteries. The generator is similar to an electric motor, but it acts only to produce electrical power. It is used mostly on series hybrids. The batteries in a hybrid car are the energy storage devices for the electric motor. Unlike the gasoline in the fuel tank, which can only power the gasoline engine, the electric motor on a hybrid car can put energy to batteries as well as draw energy from them. The key to a hybrid car is that the gasoline engine can be much smaller than the one in a normal gasoline powered car and makes it more efficient. According too Maggetto, ¡§this smaller engine can provide the power your car needs to keep up with the more powerful cars on the road. Compare a car like the Chevy Camaro, with its big V-8 engine, to the hybrid car with its small gas engine and electric motor. The engine in the Camaro has more than enough power to handle any driving situation. The engine in the hybrid car is powerful enough to move the car along on the freeway, but when it needs to get the car moving in a hurry or go up a steep hill, it needs help. That "help" comes from the Hybrid Vehicles 4 electric motor and battery this system steps in to provide the necessary extra power¡¨. Besides a smaller, more efficient engine, hybrids use many other tricks to increase fuel efficiency. Some of those tricks will help any type of car get better mileage, and some only apply to a hybrid. According too Gottlieb (1994), ¡§To squeeze every last mile out of a gallon of gasoline, a hybrid car can: „h Recover energy and store it in the battery - Whenever you step on the brake pedal in your car, you are removing energy from the car.

    Affect of Oil on Our Lives People have been talking about running out of oil for a long time. There are indications that a few more discoveries are still possible. That's good news, but for how long can these reserves of oil last. Oil has been formed on earth since the creation billion of years ago and in one century we have consumed most of it. At least, we have used up the easy to extract oil and the vast reserves remaining in shale and other such marginal deposits are very expensive to extract. There are promising technologies that may make the extraction of that oil cheaper and cleaner.

    Alternatives to oil, coal, and natural gas only provide a small proportion of the electricity needed to power U.S. factories, businesses and homes. However, as worries increases over the high costs and environmental effects of reliance on limited natural resources, more Americans are looking to alternative energy for the future. The burning of these fuels causes severe air pollution and thus contributes to the “greenhouse effect.” This enormous amount of consumption will be the ultimate cause of the scarcity of oil in the future and of environmental pollution. If people do not develop any subs

    UGBA167 Question 1 The three factors that I see most relevant to Geely’s manufacture of the TX4, ordered by importance are: popularity of TNCs, prices that competitors set, regulation on the taxi industry, and the economy. TNCs have become increasingly popular in metropolitan areas because they address problems with the taxi system. These issues include: location, safety, payments, and supply. If TNCs continue to grow and take market share from the taxi industry, the demand for all taxi cars will decrease which will in turn affect Geely.
