In mid May the Japanese Government has launched a stimulus package to boost the demand for energy efficient household appliances with a new eco-points system, details of which will be made clear in the next month after the Diet’s approval of the supplementary budget for this fiscal year.
The aim seems [en] to be in the wake of the recent attempt to re-launch the image of Japan, home of the Kyoto Protocol, as ‘the’ country of technology which is also environmentally friendly. Also perhaps to mark the differences from the near competitor, China.
Actually, the ‘ecological trend’ itself is not a new phenomenon. For the last few years, in fact, many venture companies have been trying to develop new technologies as well as ‘eco friendly’ materials to use in the everyday life.
While it would not be possible to cover all of the eco-technologies, here are several interesting, new prospects that have been gaining momentum in the past year.
Se-goiken explains the details of some materials developed by Japanese companies (names of which have yet to be revealed), an initiative taken also in many other countries that have been trying to reduce the waste of precious resources.

A Japanese company has succeeded in creating a new fibre by mixing cotton and material made from banana stalks (in the last few years more than 1 billion of stalks has been disposed of as a waste).
They already make shirts and trousers from the new fibre and in the Spring, jeans will be put on the market.

A venture company has developed a fibre made from bamboo.
Bamboo forests grow very fast and with a very little burden on environment because the quantity of CO2 that they can absorb is very high. Just the fact of growing a bamboo forest is eco-friendly in itself. Also the raw material can be bought for 1/20th the cost of cotton.
At present the products made 100% of bamboo seem to be only towels and tissues, or such.
[…] If we continue on the path of innovations in the technological revolution mentioned above, I believe that the future for Japan will be much brighter.

Theoretically it would be possible to generate energy in any place where vibrations occur such as keyboard typing or to objects moving etc. This raises the possibility of producing energy geared to the need rather than producing electricity in abundance.
*Here is a video [ja] by TV-Tokyo that explains how the invention works.
Lastly, consultant Shimo3781 introduces us to a trend quite common nowadays in the building industry which aims to increase the number of green areas in the cities yet also produce power savings.

There we grew sweet potatoes in the process of creating a green space. […] Two benefits for the price of one: fresh vegetables as well as energy saving.
Though the temperature of the exposed concrete surface reached 55 degrees, under the sweet potato’s leaves the surface temperature was halved to a more reasonable 28 degrees. An outstanding result.
Because this helps to control the temperature inside the building, the air conditioning system will be used less.
[My personal view] is that many new and different methods for the ‘housetop planting’ will be tried from now on.
