Indeed. I'd be interested if Wave Swell Energy have any plans to develop the idea more along the lines you've described, now they've somewhat proven the concept, or if they're planning on sticking with the current design, which would seem to have only niche use in remote areas that are underserved by grid supply, and suffer poor wind / solar viability for at least some part of the year. So probably nowhere.
