Given we are in a world of 500 km underwater interconnects and synchronous grids that span up to eight time zones, I am not sure why you think electricity needs to be generated right next to cities.
Though, that said, existing urban rooftops are over a third of the required area to power the world, so you might as well stick some there while you are at it.
- tired_man 11y agoTransmitting electricity is quite a bit different from transmitting bytes. That's the main reason we are using Alternating Current rather than Direct Current to power virtually everything.
- elektromekatron 11y agoI'm not talking about data cable. Was referring to NorNed, a 500km HVDC 700MW interconnect between the Netherlands and Norway https://en.wikipedia.org/wiki/NorNed https://en.wikipedia.org/wiki/NorNed, and the Russian power grid IPS/UPS https://en.wikipedia.org/wiki/IPS/UPS https://en.wikipedia.org/wiki/IPS/UPS edit - the limits to how far you can push transmission are very high indeed. For instance, here's a study from 1984 that puts an upper limit on AC at 3000 - 4000km and for DC at 7000km. http://large.stanford.edu/courses/2014/ph240/sell1/docs/paris.pdf http://large.stanford.edu/courses/2014/ph240/sell1/docs/pari...
