An Ideal Automobile to Change Our Future

Kurume National College of Technology

Introduction
Izumi: We came from Kurume National College of Technology.
Akari: I’m Akari Tsutsui. This is Miki Nakamura.
Miki: Akari and I are studying in Department of Material Science and Engineering.
Izumi: I’m Izumi Inoue. I major in Biology and Applied Chemistry.
All: Today, we would like to talk to you about Eco car!!

Skit 1
Daughter (Akari): Hey mom, I have a question.
Mother (Izumi): What?
Daughter (Akari): What’s Eco?
Mother (Izumi): Eco? Well….
Narrator (Miki): Like this, nowadays, we are familiar with the word, Eco, aren’t we? But we might not know exactly what eco means.
Skit 2
Daughter (Akari): Now I’m soooo curious about eco.
Mother (Miki): Hey come over here, Akari!!!
Daughter (Akari): Sorry, mom. Don’t leave me.
Hey mom, hat’s that car, mom??
Mother (Miki): That is the eco car. It’s good for the earth.
Daughter (Akari): What is it different from a regular car, mom?
How is it good for the earth?
Mother (Miki): Let me see….
Narrator (Izumi): Are you interested in eco cars? This is a questionnaire on eco car. We conducted the research on how young people of our age think about eco cars.
Akari: As you can see here,
Miki: 77% of our friends are interested in eco car, but among who answered they are interested, only 29 % of them actually own an eco car.

Main Body
Akari: And now, what do you know about eco car? You know, Eco car has a lot of advantages. For example, because not much oil is needed for eco cars, they are less affected by escalating gasoline price. Also, they have good gas mileage. And they are very kind to the environment for they emit little CO2, which is regarded as one of the causes of global warming.
Miki: But, of course eco car also has disadvantages.
Little variation of designs, high prices, and lack of infrastructure building for hybrid cars. We need a factory called Hydrogen Station, where we treat hydrogen necessary to make hybrid cars. Not just we need more money, we need to develop more advanced technology to build a Hydrogen Station.
Izumi: In the questionnaire, we asked what we could do to improve Eco cars. The answers are summarized as follows.
Akari: In order to solve those problems ,we offer suggestions from two different perspectives.
A & M: Approach from …….Material Sciences.
Izumi: And approach from Biology and Applied Chemistry .
I will talk about the Ecology from an aspect of scrapping cars.
Today, in this world, a large number of cars are being consumed. At the same time, this causes a big problem. It is garbage disposal. Especially tires cause a serious environmental problem because they do not decay. After they are used, some are recycled but almost all of them are burned or buried in the ground. Therefore we need to develop new system which is healthy for the earth.
A & M: But, how…?
Izumi: Now, I suggest a process which uses “MOE-Kin.”
A & M: MOE-kin?…is it in Akibahara??
Izumi: No way. MOE-Kin is a microorganism which was discovered by Dr. Mori, Dr. Oiki, and Mr. Eto at Kurume National Collage of Technology in 1996. The name MOE is an acronym from their names.
A & M: In our college? Did you know that?.
Izumi: This microbe has a special ability. It can resolve a synthetic rubber, which is the opposite of natural rubber. It has a potential to be the first microbe for synthetic rubber resolution.
Miki: What does this microbe have to do with tires?
Izumi: Tires are made of SBR, which is a kind of synthetic rubber. Using this microbe, we’ll be able to dissolve tires, putting them in a recycling system.

Akari: According to our survey, the most requested point to improve eco car is the weight of car body.
Miki: Look at those parts. Those are car body sample products used for real cars.
Akari: Hey, Izumi, can you hold these a little bit?
Izumi: Well……
Miki: How do you feel?
Izumi: This one is much lighter than another one. What’s the difference?
Akari: In fact, they are made of different materials. The right one is made of aluminum and the left one is made of steel.
Miki: The density of aluminum is 2.7 kg/cm3, and the density of steel is 7.9 kg/cm3. In Japan, steel is still being used for about 80% of our cars.
Akari: And then, could you look at this figure?
Miki: This figure shows utilization of aluminum for car bodies in Japan
Akari: Now, the demand of aluminum is gradually increasing.
Izumi: Waaao! Aluminum is amazing! But when I have a chance to buy an eco car, I would like to get cute one, not just light one.
Miki: Doesn’t matter, if you want a car with cute design, aluminum is more suitable for bending work.
Akari: In other words, a round shape which is popular among younger generation and women, will be possible using aluminum as a substitute for steel.
Miki: In addition, aluminum improves recycle efficiency.
Akari: The demand of aluminum is sure to increase in the future.

Conclusion
Izumi: I am going to make incredible recycling system using Moe-kin. With Moe-kin, we don’t have to do formation disposal. It will be good for the earth by using this system.
Akari: I am going to produce car bodies with unique and stylish design using aluminum. That is, women would like it better than before.
Miki: I am going to change materials of car bodies. I will use aluminum instead of steel stock. Our lighter cars can keep the fuel cost very low.
All: This is our ideal automobile in Future.
