Hydrogen Vehicle

According to Marsha Walton (March 19, 2008) in this article “Florida airport tests hydrogen engines,” in the Orlando international airport, hydrogen engine vehicles are being tested. Those cars have the advantages of being quiet and having little environment impact. But, also they got disadvantages such as expensive facilities and few vehicles in use. The Orlando airport is being challenged to improve its hydrogen vehicle system. “The ultimate goal is hydrogen fuel cell cars,” which are less expensive to manufacture. Many companies and researchers are investing in the hydrogen test project which will bring us a green environment.

Nowadays, we need alternative energy, because oil is an exhaustible resource. Thus, the scientists should develop hydrogen energy. Also, the hydrogen cars have more protection of the environment than gasoline, and the scientists should develop electric power.

First, the scientists should develop hydrogen cars, because hydrogen cars now suffer from fuel tank explosions. Many scientists have tried to develop a fuel tank which is made strongly. In Canada, they have made stronger fuel tanks than before, because they want to commonly use hydrogen cars. Also, we should think about the fact that when people use hydrogen cars, they must be made safeky. If the hydrogen cars explode, it makes a bigger problem than gasoline, because hydrogen is very explosive. Thus, the scientists should develop hydrogen cars, because we want to safe.

Second, the hydrogen cars have more protection of the environment than gasoline. The gasoline cars can make air pollution because the gasoline cars emit exhaust gas. However, the hydrogen cars do not make air pollution. Thus, the scientists think that they should develop hydrogen cars, because it cannot destroy the environment. Nowadays, the world is focusing on global warming. Many people do not want to influence the environment in a destructive way. So, the scientists should develop hydrogen energy.

Finally, the scientists should develop electric power, because we need another kind of alternative energy. If we exhaust our supply of gasoline, we should find another kind of energy. The electric energy is not an exhausted resource. Thus, we should develop our electric energy. Nowadays, we are using electric energy a lot, and we do not want to affect the environment. It could help us. So, we should develop electric power.

In conclusion, we should try to use hydrogen energy because it can be a substitute energy from gasoline. Also, electric energy can be a substitute for gasoline. These are not exhausted resources and do not affect the environment. So, we should try to use these resources because now we have a big problem about global warming.
