Nope. The point is that Geo generation on Iceland remains cheap while the cost of other forms goes up and so it's worth the cost to transport it long distances. But the cost of transmission can't be an order of magnitude greater than it is today (your assertion) or it wouldn't be cost effective to do so. From Trippy's link: So NO, I don't agree with you. No, they are more expensive, maybe twice as expensive. Not ten times as expensive. That was the issue. Yeah. Not at all related to the issues of laying a cable. All that means is you don't make the cable outer layer out of steel. So since they weren't planning on doing so it's not an issue. Actually no. The technology changed. But even still, 25 years is a far longer time than one needs to recoup your investment, and when you pull up the cable it is recyclable.
