1. Ocean Current Energy in Japan!!
Number:
Daisho Wakabayashi

2. Ocean Current Energy Ocean Current Turbine
The electricity is generated by an ocean current turning a turbine.
Ocean Current
Turbine

3. What is the good condition!?
A necessary condition for ocean current electric generation
An ocean current exists.
Must
Good conditions for ocean current electric generation
An ocean current velocity is fast.
A quantity of current is large.
An ocean current is stable.

4. Where is it used in Japan !?③
③ Oyashio Current ④
④ Liman Current ②
② Tsushima Current
The main ocean currents in Japan are ・・・
WARM ①
① Japan Current
COLD
Expressly, It has started to study about Japan Current now.

5. Where is it used in Japan !?
This area is the most available for electric generation.
Japan Current velocity

6. Japanese Company’s Activities
For example・・・
It was announced that IHI and Toshiba started research for the development of ocean current generation system.
Nova Energy company developed new turbine called Maguro turbine.
Main activities
analysis
calculate production cost
decision of location
examine environmental load
consider overseas deployment

7. Conclusions
The ocean current electric generation is not put to practical use in Japan.
An ocean current electric generation will be investigated by Japanese company from now.
Japan has good environment “Japan Current”
An ocean current energy will become efficient energy in the future.
