Surface waves (Beaches 50m from the shore) energy extraction

Hi,

Can the proposed technology concentrate on energy extraction from the periodic incoming and outgoing waves on the beach rather than wavy action of the ocean surface waves?

Thanks,
Teja

Hi Teja,

Are you asking if you are able to extract tidal energy?

Thanks in advance for the clarification.

Hi,

No, we are not talking about tidal energy. We are asking if the simple waves (advancing and receding water front) seen on the beach can be used? We plan to design a device to extract the kinetic energy in the waves hitting the beaches like the ones in the link below.

Please let us know your thoughts.

Thanks,

Hi,

Could you please clarify on this wave condition further. In the documentation it says "All solutions
that make it to the DRINK Stage will be evaluated at an open-water test site with an
anticipated average- to low-energetic wave resource. "
A beach front with breaking waves is not an open-water test site.
Need clarification on this because these two wave energy states are completely different.
Also if there is an open-water test site then a deployment work boat is required to install the equipment, that boat with not fit in the shipping package.
Cheers

Just wanted to let you know that we've seen this and will respond back with more information soon.

Thanks for your patience!

Hi Peter,

Thank you for your clarifying question! We are anticipating a near-shore testing environment, that is not blocked or has deep water. Although the final site is yet to be finalized, we anticipation that site conditions will have these characteristics:

- Significant wave height range between 0.5m -2.0m;
- Average wave period range between 5-15 seconds;
- Water depth of 2-5m; and
- Deployed less than 1 km from shore.

Hopefully this helps to clarify the conditions for the DRINK stage.

Thanks again!
