That's because the maths is wrong. 5,000 x 5,000,000 is 25,000,000,000, not 5,000,000,000

Don't worry, because the price/kwh calculation is also wrong.

Let me try, with average price 4.5 million/mile and 40-year lifetime:
4500000/1.6 * 5000 / (12000000*0.75*40*365*24) = 0.00445 USD/kWh
doesn't sound too shabby, yes, or did I miscalculate it too?

This price matches my intuition. Power transfer is absolutely everywhere, even in many of the poorest of countries. It is simple and requires only very common materials and similar construction techniques roads and buildings are built with, everywhere. Transfering power for 500-1000km is nothing special currently. I fail to see the exponentially increasing complexity and cost people are assuming when discussing improving the current transmission systems.

That makes more sense, isn't it? They were building 750kVAC transmission lines in the 70s all over East Europe, to connect countries to nuclear plants (and to make them dependent on the power delivery from abroad). It's really not rocket science, and these lines still work, even if they are not used for one reason or another. And nuclear costs somewhere at 1-2c/kwh, that's how much existing nuclear plants are bidding for generation. Meanwhile the clueless greens are telling us that nuclear is cost prohibitive while they are gluing themselves to Rembrandt paintings.

Ah, damn.  I did the maths at $1 billion and forgot to square it all.  Anyway, I promise I can math.  Maybe.
