Wave energy

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

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

Wave activated generation

  • Mechanism of the generation

Incoming waves

Dilatational wave

Wells Turbine

Wells Turbine

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

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.
