video reflection

The film that Who Killed the Electric Car? was written and directed by Chris Paine, and produced by Jessie Deete. electric cars began to occur on roads all over California. They were quiet and fast, produced no exhaust and ran without gasoline. But Ten years later, these cars were most entirely gone.
In 100 years ago, the electric car are good choice because of quiet, smooth and could be charged at home which is better than gas car. The film explores motive like speed and cheaper oil that may have pushed the auto and oil industries to kill off the electric car.
The film investigates the birth and death of the electric car.
Because of the gas cars the city are all around Smoke, which cause very serious effect of the people like disease and global warming. As the amount of cars increasing children are not allowed play outside.
Then GM companies come out use of solar to build electric car, the sun resource. And they are succeeding to create an electric car. And the Air Resources of California thought electric car are another resource to solve problems.
They created the EV1 that is fantastic by response. But these are issue that people are used to gasoline car have a lots of oppugn. And they said, “The environmental benefits of EVs are dubious.”
Anther reason for the electric cars cannot beat gasoline car that was the high purchase cost. 
from birth to the mysterious demise of the course, as well as in the renewable energy industry plays an important role in the country's future life, play a supporting role, and in its cultural and economic aspects of the layers of influence, and from the progressive liberalism into the new Conservative government of the United States and important industry response made a profound exploration.
The film show makes people thinking about the increasingly important role that renewable energy plays in modern society.

radio reflection


There are 6 episodes include how the cardboard boxes, packing tubes, Tetrapak, aluminum cans, glass bottles, and plastic bottles and jars made. These radios show how to make above products by recyclable materials and the process during made.

Cardboard boxes was invented 1870s by accident. 

Cardboard boxes are widely size, shapes and colors. These are three or more layers. Each layers of cardboard boxes made by rolling recycle paper separately then combine together. And cut the board by 9 times depend on the size they producing. This episode shows the process of how to make cardboard by manufacturer. The product line produces 8,000 boards for hour. These also are set up process to cut the part of they suppose to. And the wastage produced during the process would be recycle.
Packaging tubes discovered flexible metal containers for their paints back in 1841. Now these are have wide range of things, like toothpaste, glue and skin cream. These are many technology used in the packaging tubes like normal paint to sun burnt. Packaging tubes are use for contain very useful item.
Tetrapak containers keep drinks and food product safe and stock up to years without refrigeration. Tetrapak containers made mostly from paper, they are recyclable and the things like paper towels and toilet paper.  Tetrapak made by several different layers like plastic layer, paperboard, etc. tetrapak entirely made by recycle materials.
This episode introduces the process of recycling. Put into trash bin is the end of story of the garbage but for the recycling of process is just beginning. Now day garbage assort very well by technology of rubbish disposal station. Separate Trash is still worth so much money if they treated correctly.
Aluminum cans are always recyclable and made by aluminum sheet roll to cut. The other advantage is so lightweight and easy to casehardened. After the cans formed, they are needed to wash in high temperature degrees. The print is really high efficiency to make 1800 cans per minute. 
Glass bottle of jar are green. Glass also a good nature recycles material and wastage less and long term recycle. The different form stencil can make different bottles from the form machine.
Plastic packaging is becoming more common because they are lighter and not breakable as glass. Many types of plastic bottles are mostly made form a type of material as polyethylene and PET. They can make by mix PET and recycle PET. The efficiency of the manufacture is really high.


In the DSD GPANL Recycling season that shows the structure of wastes and how these different wastes are recycled, video shows us the recycling is the best way to reduce the wastage of our daily life. Most paper are also recycles, the waste paper are count about 60% of material used produce new paper. Food containers are made from 80% cellulose that consists of long and high grade paper fibres.  The tinplate are useful for the steel work. These videos tell us that are very important to use the recycle material to get the long term live of the human.
