How is ocean wave energy nowadays used in Japan? 11720301 YousukeKouchi
Waveenergy • Peculiarity ◎energy per area is high !! <comparison> 20~30 times ofsolar energy 5 ~10times of wind energy ◎Generation effectchange by environment . ◎Easy to do a prediction of the quantity of generation.
Nowadays used in Japan • Wave activated generation 3types Convert to air energy Convert to mechanical energy Convert to potential energy of the water Many Researcher research wave activated generation system now.
Wave activated generation • Mechanism of the generation Incoming waves Dilatational wave Wells Turbine Wells Turbine Air flow Air room Air flow Air room Example "Mighty Whale”
But・・・ • It does not spread in Japan. Because ・・・ ◎ It need high cost . ◎Consideration of the safety is difficult. ◎ Harm a scene.
Conclusion • Wave energy used to Generate electricity in Japan. • But wave activated generation has a lot of demerit . • Therefore it does not spread in Japan. If wave activated generation improve these demerits, it is difficult to use wave activated generation. We struggle these demerits.
