This technology looks interesting but I am confused by the implied relationship between the application to power offshore Oil and Gas and the GHG savings if used to power 460 homes.

Since this is a climate contest, it would make sense to highlight the change in emissions you propose to achieve within the context of powering O&G operations.

Continuing in that vein, I am left wondering why coastal cities, ports, ferry terminals, anchored freighters, would not be feasible users of this technologies. Does it work nearshore? Is the average wave size not applicable nearshore? If not, then would it not make sense to adapt the technology to those applications given the amount of global energy they consume.

Hi Betsy,thanks for your appreciation. Of course, there are several applications of our technology, both in O&G and in the residential sector as you mentioned such as coastal cities, ports, isolated resorts, anchored freighters and any kind of energy need surrounded by water with a minimum wave height between 1 to 3 mts. I have to say that more than 50% of global population live in the coast or nearshore. Our technology works both nearshore and offshore.

Hi Oscar Villanueva,

Nice to go through the proposal description.

The described wave energy convertor sounds a promising move in the climate change mitigation process. Please consider providing more information / input on the following:

1. The pre-requisites of the field survey data / requirements for assessment of wave energy potential at the project sites. How much efforts / pointers to go in for site selection, pre-project investment and other requirements for project promoters to consider.

2. Please enlighten the prospects of having such projects in the Islands world over - islands nations & small islands of the various countries in particular. This would be quite relevant for sourcing green climate funds from multilateral funding sources world wide as well as Climate Co Lab contest.

3. With substantial investment already made in the research and development; the technology evidences strong footing for commercial realisation.Please elaborate the probable sites where you plan to set up the pilot scale projects.

Bests,

Manohar

Dear ARRECIFE SYSTEMS team,

A nice proposal from your team. I particularly like your team composition as decribed in your proposal; you might be able to capitalize on your different expertise. 

In addition to other comments which you have received, I will like to call attention to your project's name (Arrecife Systems). I am aware of a port city in Spain called 'Arrecife'. It might help if you could explain the motive for choice of your project name since such a proper name already exists.

Best wishes,

Olawale

Dear Olawale,

Thanks for your comments. Talking about the name of the project ARRECIFE is not related to this town located in the Canary Islands-Spain, but for the relationship between the natural behavior of the coral reef where small animal harness the power of waves like our device with the direct action turbines.

Best wishes.

ARRECIFE team.

Dear Manohar,

I have to thank you a lot your comments and I'll try to expand more on the proposal description, both the location importance, the market adressable and the early adopter o pilot projects at the very beginning.

Best wishes.

Oscar Villanueva.

Dear Oscar,

Thank you for uploading the proposal. I’m interested to learn more about the technology behind your idea. In particular, it would be useful to see a more detailed comparison between ARRECIFE's solution and the current options for wave power generation. Here are a few other thoughts that I had while reading through the proposal:

- You might consider adding a diagram and photos to help illustrate the concept.

- What effects would multiple operating turbine platforms have on marine life?

- You compared the technology to a coral reef several times. Could you elaborate on how exactly they are similar?

Best,

Lenny

Dear Lenny,

Thanks for your comments. I'm happy to answer your questions:

-I'll add this media information about our prototype

-The cross-flow-direct-action-squirrel-cage-turbines are formed by non-cutting blades, adding to the sense of rotation, the very low speed and high torque make our device very safety for the sea wildlife.

-Arrecife means Coral Reef in spanish and the explanation is as simple as the behavior of our turbines opposing and absorbing all the energy of waves in the same way as a coral reef do.

I wish I can clear your doubts.

Best,

Oscar.

Dear Arrecife Team, 

You're mentioning something very important in your proposal --- derisking. I find it crucial aspect of business in a very risk-averse, cannot-fail industry, such as energy & utilities. 

I echo Lenny - it would be great to see some drawings. I'm still trying to visualize the tech and have to admit that the description is a bit misleading (it took me a while to get from "at any sea depth" + "floating" = "independent of the depth of the water"). I also agree with Betsy regarding the comparisons - maybe a better baseline than a house would be GHG savings against a diesel generator, common on islands?

At the same time I think you might be selling yourself short. I agree that you could try to bring down the costs down to, say, 1/3 of the final price, but the growth numbers you're presenting are very conservative. If your technology is as good as you claim, you should be able to sell more than ~15MW over the next 7 years!

Dear Michal,

Thanks for your comments!There were so helpful!I appreciate it, but I cannot attach more pictures, I don't know why...but maybe you can taka a look into our website in order to know more about the features of the product and how it works.

Thanks another time for the feedback.

Dear Arrecife team,

Well done. Great work.

I would like to ask that, after you have captured the wave's power, did you discover any significant change in the wave? I mean was there a reduction in the power of the waves before and after capturing the power? And was there any effect on the surrounding ecosystem?

Thanks.

Adejoke.

Hi Adejoke,Our technology behavior is like a coral reef so we absorb energy from waves destroying them because they brake completely through the serial turbines and they completely or almost disappeared. If this happens offshore doesn't matter because waves from the sides form another waves and they will arrive completely formed to the shore not damaging the bentonic ecosystems. We also can protect the litoral and harbors installing our turbines near the shore protecting people and facilities from huge waves.Best regards,Oscar Villanueva.

Thanks so much for your reply. I appreciate the aspect that your device could protect people and facilities from huge waves near the shore. Really wish you made it to the voting stage.

All the best.
