Reading Reaction "Electric Racer"

This article describes that some teenagers, a group of Philadelphia students, could convert the gas-powered vehicle into the electric-powered vehicle (EV) for the contest. They also have made a completely EV by changing a gasoline engine to an electric motor before. Concerning the gas-powered vehicle, the explosive combustion inside the cylinders creates the motion needed to revolve the wheels. On the other hand, an EV can run by the energy provided by batteries. Furthermore, EVs do not create pollution such as smog which is produced by gasoline engines. And also, it is easier to maintain the EVs than the gas-powered ones. However, the EVs have some drawbacks. Whereas it takes within a minute to fill the tank of the gas-powered vehicles, recharging the batteries for the EVs takes six hours. Moreover, the ordinary car can run several hundred kilometers until the tank get empty. In contrast, the EVs can run at most 160 kilometers with one recharging. However, the technology of the EVs needs to improve for our future, and also studying these EVs can give profits to students.

This article makes me surprised very much because the teenagers could create the completely EVs. At the same time, I also feel envious the circumstances of American students. In Japan, most high-school students have no chance to build the car. If the students can experience the practical work and training besides the cars in their early age at the school, more students can perceive the necessity of the sciences, math, physics and technologies.
Nowadays, we can hear that there are many problems of pollution against our life and the earth. And also I know the EVs and other eco-car(ecologically friendly car) have been made progress. In the other hand, some people including me prefer the exhaust noise of the gasoline engine and vibration of the gas-powered vehicles. Therefore, I do not think the gasoline engine will disappear from our society in the near future. Furthermore, the internal combustion engines have also been improved as much as eco-car in many country such as LEV(low-emission vehicle). In addition, harmful gas, such as COX, are created in making the electricity for the EVs at the thermal power plants. I think what is important is that considering how much convenience we are able to sacrifice to the earth.
