A spider still weaves its web one strand at a time...

With the right ‘complimentary’ technologies, this ‘power’ cable could detect subs quite effectively

high voltage direct current

Then what... a Russian sub can just turn the lights out in Western Europe?

Europe would still have their own power generation... It would just improve generation/consumption mismatches. By island hopping you could shorten the buried lengths, to make replacing damaged sections easier.

Happy valley goose bay to the tip of Greenland, up the coast to kulusuk, across to Iceland, then to faroe islands then maybe Shetland, Bergen, Stavanger etc.

Seems like the sort of thing that isn't unreasonable to study.

this is why you dont publish the other 6 communication projects.

Apparently they power it from both ends. So the distance to maximum loss will be the halfway point. So very roughly about 16% loss from either end based on the HBE numbers you provided.

Upping the voltage has limits because you're actually powering repeaters along the cable.

edit: Oop my bad. I thought this was about the proposed data cable. Not power.

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.

Laws of physics be damned

Why buy from Canada when Russia and the Middle East are right there?
