Wouldn't it be cheaper just to whip a cable over to Australia?
We could bore a series of holes through the center of the planet and then use gigantic orbital crystals to create a array of lazers to focus the sun's light through to the dark side of the planet.
I'm a fan of using magical heat-producing rocks to boil water and spin turbines, but admittedly that has fallen a bit out of fashion.
This could be nuclear or coal
There's an argument to be had that burning coal doesn't count as magic while fission does, but in any case, good catch, let me amend that to: magic heat-producing rocks that don't fill the atmosphere with dinosaur squeezings.
It's temperature would have to be maintained around absolute zero to compensate for the transmission loss, for that we would need a continuous source of cheap, clean energy.
Would it?
I thought about a bunch of small satellites with mirror foil.
The solution to balance it is batteries or any other energy storage solution.
Why not just put the farms in space and beam the power back?
This gives me a flash back to SimCity. I wish someone told me the clean microwave plant occasionally malfunction, sending an orbital ion cannon through my downtown.
I thought about this too, but had the impression that only mirroring a bit of sunlight around would be cheaper and safer.
