Nicole Mazza Dr. Penelope Hope March 6, 2011 Writing 105-Section 7 Exercise 4.3 Janice Hunte Professor Case English 101 22 January 2007 The Hydrogen Fuel-Cell Car A serious problem that is talked about all over the world is Global Warming. According to Michael D. Mastrandrea and Stephen H. Schneider, “Global warming is an increase in the average temperature of the Earth’s surface. Since the Industrial Revolution, that temperature ahs gone by up 0.7 to 1.4 F.” The authors point out that Americans are responsible for almost 25% of the greenhouse gas pollution that causes global warming, even though they make up only 5% of the worlds population. The authors also note that global warming is caused primarily by the burning of fossil fuels, such as coal, natural gas, and oil, and that much of this burning occurs in the gasoline engines that power automobiles, as well as “in factories and in electric power plants that provide energy houses and office buildings” (47). It is clear, then, that gasoline-powered cars are a major cause of the greenhouse gas pollution that is responsible for global warming. In the future, some believe, this problem maybe solved by vehicles powered hydrogen, a clean-burning and abundant energy source, which will become the norm for roadway and high way transportation. In recent years, the major automakers have been exploring alternatives to the gasoline-powered internal combustion engine. Recently, the electric car was widely seen as one viable alternative. Between 1996 and 2003, the Big Three U.S. automakers produced prototype electric vehicles, among them G.M.’s EVI, that were leased to a limited number of consumers. But these battery powered, zero emission cars proved problematic. Most had to be recharged every 100 miles or so, considerable limiting their range; and drivers found relatively few recharging stations. Manufactures could never figure out how to reduce the batteries to manageable size or how to produce them at

reasonable cost. In the end, the automakers reclaimed all but few of the leased electric vehicles and destroyed them (Ortiz D1). Over the years, many alternative fuel technologies have been proposed, but all have shown limited practicality or appeal. Compressed natural gas (CNG), which powers the Honda Civic GX, is reliable, clean burning, renewable (through fossil) fuel, in plentiful supply. But because of their limited ranger, about 200 miles, and the absence of significant CNG infrastructure, natural gas and vehicles are employed primarily in fleets that have relatively short routes and access to their own filling stations (Neil). A third alternative fuel vehicle, powered by compressed air, is being developed by a French company, Moteur Development International. A prototype car can achieve a speed of 70 miles an hour and has a range of 120 miles. It takes about four hours to recharge the onboard air tanks, using a compressor that can be plugged into a wall outlet. So far, the company’s U.S. representative has not sold any manufacturing franchises in this country
