  1. I was doing a similar thought experiment, a number of days back, and I was thinking about the wires. My conclusion was not to use wire, but to use pipelines. A pipeline, used for transferring oil or gas, could conduct electricity, we have pipelines today, and the great surface area would not require complexities of high voltage DC. The pipeline could also act as an oil / gas / water pipeline, for immediate profitability & reduced investment risk. My major concern is with salt water being conductive, as well as any moisture in the ground being conductive. Any small problem with insulation could be absolutely deadly, to a lot of stuff nearby, including people. I still like pipelines, maybe a pipeline coated in fiberglass, but a leak of saltwater in the ocean could still be catastrophic. Maybe a pipeline coated in aluminum or copper, then coated in fiberglass would be acceptable.
