Green power now

The history of the development process, the pen has served as the unknown but essential role, was, is and will be.

Commonly used today is the signature pens and pens, drawing artistic papers and drawing is more than a pencil. We do a statistical: if the average life expectancy of Chinese people 60 years and 6 years of secondary school students to read, that there are six age classes, where Chinese account for about 10%. Suppose that all the city's population (assuming 500 million) have the ability to support their children to school, there are 50 million urban middle school students, and then assume that 300 million rural people have the ability to provide for their children to school, there are 30 million rural students. So that about 80 million students. Students on the assumption that every three weeks with a pen, 17 pen with about a year. Students will use a pen that 1.3 billion annually 60 million, per person in China has exceeded a pen, this is how large and dreadful data!

The development of the pen as with the human development is to be found regularly, and now most of a cartridge pen is placed in a pen shell, pen shell cartridge from the protective effect. The same for the 21st century we will not meet the current pen style! Because it can save a lot of places. After our research team created a small, if it is

entering the market will effectively saved a large part of plastic.

These are our creators think this is a 12 cm long green pen shell: First of all, its main material is wood, it can be in the furniture factory. Second, it applies to most of the water refills, ball pen core, use the cartridge inserted into the top of the figure, with two screws secure the left to the right. If the user with greater force can start to stretch at an adjusted during the previous step. After the draw at the operation with the ability to write into the protected areas can make. Here is the timetable:

Write the paper in early May, a record to establish the theme

The end of contact factory

Public opinion survey done in early June to determine the feasibility study

In mid-June summary

A pen shell Budget:

Materials wood screws

A pen on the cost of a hair can be ignored

We have to calculate the following: Given the destructive power it deserves - a shell with the 10 than the cartridge, if there is a 10,000 individuals who use our creativity, there are 13,600 a year can be saved out of the pen shell, and its save resources, although not large, but also can not be ignored!

We act together, you and I start from the energy saving!
