I just joined this forum and this is the first topic I see!
I would be interested to see your results.
The coral projects which are using this technology don’t seem to benefit in the long term. As for using this for industrial use, I cannot say.
Here what I know about BioRock coral projects. By passing a low voltage current through seawater, this causes dissolved minerals to crystallize and to grow on the structure. It is easier for coral larvae to settle, and corals may accrete to the structure faster, but overall more time and money is wasted installing and maintaining these cumbersome systems as opposed focusing on growing corals.
Long-term the structure fall apart and can collapse under the weight of coral. Underwater projects look like a mess with wires hanging from the surface, collapsed frames, discarded frames, and frames that electricity has been cut off. Often these relics are now covered in sponges and seaweed. Not something they show you with a group but visit the first ever biorock project in Permuteran by yourself and you don’t have to go far to see what I mean.
In all the years the technology has been around there is very little scientific evidence that it benefits coral growth in the long term. And, all you have to do is look at the marine aquarium hobby. If this technology worked to grow corals bigger, faster, stronger, everyone would be doing it.
As for breakwalls and restore beach that I don’t know, and for the context of putting it on a hull, I am curious to see if this could work. You are not looking to grow corals because there is limited light, so perhaps just to create a solid mineral layer under a boat this could be an interesting idea.
