Each sphere has an estimated lifespan of between 50 and 60 years, with partial replacement of components every 20 years or so.
The concept is fascinating, but what I’m most curious about is how they achieve that longevity in seawater. Benthic life really loves to settle and build on hard surfaces.
I would imagine it wouldn’t matter how many barnacles and stuff are on it. That’s the outside. Everything important is inside, I’m assuming the intake water will be screened or filtered in some way.
Most benthic life (by number) start as tiny, motile creatures. Screens would reduce head pressure and require maintenance. Barnacles of all kinds, as an example critter, settle on everything to which they can adhere. I’m guessing the engineers considered these complications since there have been past power project failures because of sea life. I wish the article went into those mitigations. If it’s somehow a non-issue by nature of the design, my curiosity is even more piqued.

Benthic Life needs to be band/album/movie title.
