Maybe these are the windmills that drive the whales crazy? To paraphrase wind-watch.org (sounds non-partisan)
> The obvious concern that most people might guess will be dangerous and damaging to [swimming] wildlife are the spinning blades themselves. While large white spinning [turbine] blades rotating [below] the horizon or in an advertisement seem bucolic, restive, and like the perfect green energy source, the fact is that the tips of the blades can be spinning at up to 200 miles per hour. Those speeding blades can act like a giant blender for large [fish] such as [tuna] and [whales] which fly around the commercial [water] turbines and chop those [fish] up. Biologists have found that even small species of American [fish] regularly get killed from the spinning turbines of commercial [water] turbines.

My intuition is that these will be moving much more slowly than that. The turbines that they refer too are usually high pressure ones designed for generating energy downstream of a huge body of water like a resovoir.
Did you just post a wind-turbine criticism?
These turbines have a diameter of 18m and a speed of 8 to 20 rpm. So a tip speed of 7.5 to 19 m/s - about 27 kph to 68 kph. I guess that's enough to hurt a whale. Although interestingly the water speed due to the tide in this channel is up to 5 m/s - so maybe it's too turbulent for whales anyway. Do whales like fast flowing water?
this feels solvable with a cage around like you have on every pedestal fan?
that reads as nonsense. it's mixing wind and water, and all those missing words indicate that it's the product of a broken mind.
also, you, the MAGA-hallucinations against windpower are contemptible lies AND they have nothing to do with this single underwater turbine.
