That feels like a draft of academic paper written before they found the sources to put in and pad it out a bit.
I like the idea but the discussion or method section does not talk about how they plan on preventing damage to the cables over such vast distances, or how the electromagnetic forces may fuck up some of the sea life.
The electromagnetic forces surrounding a 50 MW 1000 kV undersea power transmission cable are insignificant. If the cable is shielded by a copper mesh, no electric forces escape the cable, and at 50 amps (50 MW/1000 kV), the magnetic forces outside the cable are barely above Earth's ambient magnetic field. Right outside the cable, the magnetic field is 100 microTesla, which is considered harmless to all biological processes, and at 40 cm distance, it is already well below the Earth's ambient magnetic field of ~50 microTesla.
Suncable in Australia are doing something similar, or talking about it at least. 3800km from Australia to Singapore, via Indonesia
not sure it'll ever get up by who knows
It's a long fucking way though.
Thank you a discussion portion in this paper could have said something like this, there are some math I can do without thinking to hard but there are other I cannot.
