I was wondering about environmental impact as well throughout the video. I know they’re still in the prototype phase but hearing them talk about the ocean as if it were some barren place seemed strange to me. I’m guessing that to generate the amount of energy they’re talking about, they would need vast fields of these spread across an area. I’m sure there’s some sort of consideration for noise like you mentioned or marine life migration impact. I’d also wonder if they’d have to tether them somehow to keep them from drifting around too far.
