I always thought that tides were a really underutilized source of energy.
I mean, look at the Bay of Fundy. The equivalent of all the water in all the rivers in the entire world cycles in and out every single day. Thats a lot of movement and a ton of potential energy there.
As the article notes, part of the problem with large-scale operations like this in the past is that they disrupted ocean life to a significant degree; this one is different in that it (theoretically) doesn’t, since it’s smaller and mobile and not tethered to the seabed.
The article doesn’t say anything about it not being tethered, so I’d assume it still is.
The sea is very corrosive which destroys moving parts :(
Not many people live there, but W. Australias’ Kimberley Coast has a section where the tide rises 36 feet.

Waves big enough to surf arrive.
Here is a video of the technology from Minesto the company that produced the system.
That’s interesting. I love seeing new ways for renewable energy. Though it does seem like the tether would be the weakest point. But I am not an engineer.
I wonder how the sea life will react. Will they get stuck in it? Will they leave? So many questions only time will answer.

The best thing is these provide continuous power except when the tide is “turning”… however that might only be a 20 minute lull it will be at a different time of day for each installation.
