How is ocean wave energy nowadays
used in Japan?
11720301Yousuke Kouchi
Wave energyO Peculiarity◎energy per area is high !! <comparison>20~30 times of solar energy 5 ~10 times of wind energy◎Generation effect change by environment .◎Easy to do a prediction of the quantity of generation.
Nowadays used in Japan
O Wave activated generation
Many Researcher research wave activated generation system now.
3types 1. Convert to air energy2. Convert to mechanical energy3. Convert to potential energy of the water
Wave activated generation O Mechanism of the generation
Wells Turbine
Air flowAir room
Wells Turbine
Air flowAir room
Incoming waves Dilatational wave
Example "Mighty Whale”
But ・・・O It does not spread in Japan.Because ・・・◎ It need high cost .◎ Consideration of the safety is difficult.◎ Harm a scene.
ConclusionO Wave energy used to Generate
electricity in Japan.O But wave activated generation has a
lot of demerit .O 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.
