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.
