The History and Advantages of Electric Cars
Early electric vehicles may have appeared as early as 1830. Scottish inventor Robert Davidson constructed the world's first prototype electric vehicle in 1837, but historians generally credit J.K. Starley, an English inventor, and Fred M. Kimball of Boston with building the first practical electric cars in 1888. Later in the in the decade, William Morrison of Des Moines, Iowa, constructed his version of the electric vehicle in 1891. His vehicle required 24 storage battery cells, took 10 hours to charge, and could run for 13 hours. It could carry up to 12 people and had a 4-horsepower motor. His car could reach speeds up to 14 miles per hour. Morrison, however, never mass-produced his…show more content…
It is quite possible. However, that an electric storage battery will be discovered which will prove more economical, but at the present the gasoline or naphtha motor looks more promising. It is only a question of a short time carriages and trucks in every large city will be run on motors." Thomas Edison seemed to predict the future. Even so, in 1904 one-third of all the cars in New York City, Chicago, and Boston were electrically powered. By 1912, there were 20,000 electric cars and 10,000 electric busses and trucks were on the road in the United States. Only a handful of manufactures, notably Baker and Detroit Electric, made it into the 1930's. Former President Woodrow Wilson owned one of the most elegant cars of the period, a 1918 Milburn Electric. In the 1960's and 1970's a handful of electric car manufactures started to reappear because of the increasing concern about air pollution and a depleting supplies of petroleum. In the late 1970's and 1980's, manufactures started developing electric cars called hybrids. These cars have all the components of the electric cars plus an internal-combustion engine. In the late 1980's, one of the most e technologically advanced electric cars was the Sunraycer, developed by General Motors Corporation. This experimental car used solar energy to recharge its batteries. More recently, in 1996, General Motors Corporation announced the first modern, mass-produced car designed specifically as an electric car. Also in 1996,

The Car and Society
The automobile has had a tremendous impact on society and the environment since its development in the beginning of the 20th century. Today, there are over 500 million motor vehicles on the earth. The automobile's efficiency, style, and performance have changed over the years, but there is one thing that has not - the pollution the automobile generates. Because of the pollution, people find themselves asking whether this technology has helped our society or hurt it. Should the consequences of the automobile be cause to eliminate it? Or should science develop technology to eliminate the pollution caused by the car?
Some people believe that the benefits of the automobile far outweigh the consequences. These people…show more content…
Pollutants that are given off through the emissions of automobiles are hydrocarbons, nitrogen oxides, carbon monoxides, and carbon dioxides. Hydrocarbons emitted by automobiles create smog. Smog can create health problems for people. These problems include lung and respiratory problems. Nitrogen oxides form acid rain that hurts plants, wildlife, and the paint on our cars. Carbon monoxide reduces the flow of oxygen in the bloodstream. Carbon dioxide is a "greenhouse gas" and is a primary factor contributing to global warming.
Other reasons people are so against cars include the amount of trash cars leave behind. Thousands of acres of our earth are covered with concrete to create roadways for these automobiles. Millions of automobiles are replaced every year. The owners either get tired of the old car, or want a new car, or they buy for other reasons. This creates tons of waste. Often cars are just junked or parted out leaving masses of trash everywhere. Highways lay across millions of miles of our environment. Many habitats were uprooted and covered with concrete. People against cars say that this is not natural, beautiful or efficient. Roads are not only ugly, but they are expensive. Roads continually need to be repaired.
Scientists and engineers are eagerly trying to come up with some sort of alternative or proposed solutions to the waste the automobile creates. One proposed solution is the electric car. Electric cars were once thought to be
