content: There are a few phases of potential development. The project initially started out as hydro turbines as public artworks, these would be large scale, metal turbines tethered in tidal city waterways with led lights along the length of the blades of which the unit self powers, these would be semi submerged. The project then evolved into potential utility scale deployments, so we are looking at low cost methods of fully submerged offshore turbines, heavy duty inflatables and solids would certainly be an interesting way to achieve this, and will be the next step in research. Do you have a background in engineering or just general interest? Cheers
