China once again investing in african infrastructure.

[–] DoctorTYVM@lemmy.world 27 points 1 year ago

Out of the goodness of their heart, with no ulterior motives to worry about!

Naive question: How is the political situation between all these African countries? Are they "good enough friends" to make this work on from a political point of view?

[–] TheFairywarrior@lemmy.world 8 points 1 year ago (2 children)

I have no idea if this is actually possible, but if it ends loadshedding in South Africa I'm all for it!!!

[–] whoisearth@lemmy.ca 2 points 1 year ago

Ignoring part of the problem is cupcake and his government fucking shit up lol

Seriously though the loadshedding is redonkulous

[–] dyathinkhesaurus@lemmy.world 2 points 1 year ago

They'd have to figure out how to stop people stealing all the power lines for the copper, first.

Sounds good. If they actually manage to build it, it might even become possible for Africa to start selling solar energy to Europe.

[–] AstralJaeger@lemmy.world 6 points 1 year ago (2 children)

The distance is still a killer for that, it would either require to build an AC line from Morocco to Spain, a highly politically charged region or a high voltage dc line from Tunisia to Italy, which is quite the distance to cover.

[–] Hamartiogonic@sopuli.xyz 3 points 1 year ago (1 children)

Indeed, there are huge issues with that idea, but at least now there’s a plan to take a step in that direction. Who knows if we ever get there though.

[–] AstralJaeger@lemmy.world 2 points 1 year ago (1 children)

The main issue with this plan, in my opinion, is that there (atleast seem) to be no redundant links. African countries barely manage to share borders, not to talk about rivers and resources, for the sake of safety this system should have atleast 2 links to different neighbours.

[–] Hamartiogonic@sopuli.xyz 2 points 1 year ago

That’s certainly an issue, but I guess you have to start somewhere. If political chaos and turmoil doesn’t ignite all the cables and towers, they absolutely need to expand it later.

[–] Serpent@feddit.uk 3 points 1 year ago (1 children)

There is a project "Xlinks" to build an HVDC cable from Morrocco to the UK for this purpose. Who knows if it will succeed but it does have real backing.

[–] AstralJaeger@lemmy.world 2 points 1 year ago

Thats one hell of a distance, I really need to look more of these projects. But in my corner of europe people like to block these projects even tho they are so important

Transmitting and storing the electricity is going to be tough

Why not use the elec in Africa to create hydrogen from salt water?

Store it if needed Ship it in pipes (easier than electricity in powerlines) Ship it in cylinders

[–] Hamartiogonic@sopuli.xyz 1 points 1 year ago

That sounds like a pretty good option too. Transporting hydrogen is pretty exciting, so I wonder if there would better form instead. Maybe some chemist out there could point out some obvious way to use the electricity to make a chemical compound more suited to this purpose. Hydrogen is really nice once you start converting it back to energy, but while in transit it has some highly concerning properties.

[–] Moc@lemmy.world 3 points 1 year ago

That would be ideal

[–] tdawg@lemmy.world 2 points 1 year ago

Would love to see this! Without the influence of any foreign government interest... Ya know like how has been the case for the last 200+ years now
