How does one transmit power across an ocean? It seems like we are just barely able to send DC across the English Channel with our current technology. Does a global power grid involve super lasers? Or some kind of huge plasma cannon?
- pony_sheared 5y agoWe're currently crossing seas, not just the channel. Nice little map with stats here: https://www.nationalgrid.com/our-businesses/national-grid-ventures/interconnectors-connecting-cleaner-future https://www.nationalgrid.com/our-businesses/national-grid-ve... A few years ago I saw a talk by an industrial chemist, long distance power transmission over carbon nanotube cables. Looks like they're still not ready for primetime. https://en.wikipedia.org/wiki/Carbon_nanotubes_in_interconnects?wprov=sfla1 https://en.wikipedia.org/wiki/Carbon_nanotubes_in_interconne...

It will connect Australia with Singapore (3350km), the plan being that Australian solar arrays will provide 20% of Singapore's power. The current longest is 2500km [2] inside Brazil.
