Underwater things are expensive to maintain, nothing is 100% waterproof, so rust rust rust.

Underwater cables are no joke either, especially if you're building a network of sea cables. Making watertight is not cheap.

And there is the question of doing high power electricity under seawater. I'm not an engineer in that field, that I think it is going to being a whole lot of new headaches.

Underwater cables has been done as in all the Network connection across continents. The same with high power electricity under seawater.

None of these are new. However they are all 1 to 1 build up. These new tidal kite requires many to one. And I am not quite sure how this could be done. At least cheaply.

Those are stationary cables. I don't know anything about this field, but I guarantee you that there are going to be differences.
