Wow! They are burning in the exhibition

One of the Exhibitor bring in a burner to the New Energy Exhibition. What are the fuel? Water.

Yes, water plus fuel, and they get the same burning power and temperature as the 100% fuel. Some result even show the efficiency is much better than using conventional fuel. Wow! Fukai Green Emulsion System sugoi! Check http://www.fukaisouken.jp/.

How to produce a PV cell

The PV Japan Exhibition is suitable for all range of people who is interested to know more detail about the Photovoltic Technology. There is even a very detail description about how the PV cell is made. And detail comparison about the PV technology available and their differences. It has been attended by a lot of foreign investor especially from Taiwan and China.

There are many types of PV technology. The conventional Silicon based PV cell is said to be environmental unfriendly during its making. As the result, some Japanese maker start to produce the CIGS solar cell that are not depend on silicon and its production is more environmental friendly. Shell CIGS solar panel has winned the Japanese Good Design prize in 2007.

New Energy Exhibition in Tokyo Big Site

The New Energy and PV Japan Exhibition is one of the largest exhibition in the world. In the exhibition, you can found everything that needed to make the solar panel, from raw material, production machine, checking equipment etc. Some company even bring in the actual production machine to the exhibition. You can instantly start a Solar Panel Making business by attending it. Besides the PV, another bloom technology in the exhibition is the biofuel technology. A lot of pioneer researches had been conducted in Japan. This year, a new technology develop is the electricity generation directly from the heat. The technology has become more promosing and it is going to be study for the cost of large scale production.

Sanyo - the world largest Solar Power Producer. Currently, its production has been overtook by the Germany company.

Sanyo new solar panel called HIT is capable to solve the problem of the reducing power generation from conventional silicon-based solar panel. The above picture show the reduction of power by conventional solar panel (right) when the temperature increase.

In this exhibition, some company already developed the flexible solar "sheet" (not the hard panel), which are capable to be installed in various location.

New type of Solar sheet. So flexible, just like paper.

Newly installed Solar Panel at Kita Ayase subway station

Today, when I take the morning train from Kita Ayase station, I was so suprise with the new panel on the wall showing the electricity generated using the solar panel newly installed on the roof of the station. The electric will be used for the lighting and escalator in the station. It is one of the effort from Tokyo Metro (subway company) to reduce the CO2 emission.

The Koshigaya-Laketown - Eco and Flood Disaster Prevention New Town

The Koshigaya-Laketown - Eco and Flood Disaster Prevention New Town


The Koshigaya Laketown is developed along the JR Train line. It has been desinated as the first 20% CO2 reduction Town development project in Japan.

Solar Heat Water storage is installed on the roof

The Koshigaya Laketown JR station is located at the center of the town and can easily access to Tokyo. It to be made as the main transport system for the new town.

The Lake is designed to be a flood water retention pond. During the flood, it will be filled with water to prevent the flooding in the downstream region of Nakagawa river. In normal period, it can be used for recreational purpose.

Eco Life Fair 2008

The tricycle is become more popular now in Japan. There is some tricycle taxi in the city like Yokohama.

A Tricycle Taxi.

Electric Car. The price is still higher compare to normal small car.

How about some recycle cardboard for your kids?

An interesting experiment to teach people about CO2 emission from JACCA

Different weight of the CO2 emission per person is loaded in the beg. People can take the beg to compare the different weight for Japanese, Chinese and American. It is a good way to teach people about how much difference of the CO2 they emitted.

Another game to learn about eco life.

The wind turbin is prepared, and people can charge their handphone with the connector using the green energy.

Eco Life Fair 2008

The food court of Eco Life Fair was also very special. The container for food need to be rent from the special counter. After finishing the meal, the customer need to return the contain and you can get the refund. Waste seperation is needed during the disposal of the waste.

Various delicious food are provided. Oishi So!

Real experiment of the normal and energy saving light bulb. On the left is normal light bulb and right is the energy saving ligth. The normal ligth is now cost electric of 214 yen, while the energy saving bulb just 48 yen. It is 4 times more saving by changing to new one. Toshiba is announcing that they will stop the production of normal light bulb very soon.

The energy saving light bulb is 8-10 times more longer life span and reduce 80% of electric. If you use it for 10000 hours, yo can save about 10,000 yen.

A solar cook made of cardboard

Do the solar cook look familiar to you? It is a reuse material from the umbrella. Wow! So innovative

A very interesting Obasan.

Please look at her cap, there is a fan powered by the solar panel on the top. Good for hot summer

Eco Life Fair 2008

The children in the city has less chance to play with the toys made from natural wood. It is a good campaign to promote the natural toys. In Japan, there is a lot of replanted forest lack of proper maintainance and being left as the price is higher than the imported woods. There is still a large area of trees need to be cut down for replantation, but due to the lack of demand, and man power for the wood industry, it is now left with no proper maintainance and now become a problem for erosion. They called the poor forest as "Green desert".

GEIC is promoting the collection of message for the G8 meeting.

Mottainai Ba Chan is a very popular character in asking the Japanese people to reduce wastage.
