Thanks.

And I certainly wasn't thinking they would replace undersea cables. That seems to be a no-brainer that they'd be the way to go whenever possible. I was just curious if they'd be economical as a supplement, or for locations where running a cable wouldn't make sense (such as smaller islands).

Sounds like without some radically new battery chemistries to crank up the density, it wouldn't make much sense.
