Overhead transmission lines are so 1950s.

Invest in your country.

Japan is earthquake country so they get a pass.

India however...

[-] aeronmelon@lemmy.world 16 points 6 days ago

Japan is slowly burying all their overhead lines into the sidewalks. A lot of urban streets look so much nicer now than they did 10 years ago.

It’s probably no worse in an earthquake than the water mains, which would inherently be a lot more rigid than cables with intentional slack built into every segment.

[-] abfarid@startrek.website 4 points 6 days ago

Afaik, the problem with buried cables is that in case of a flood or tsunami they might break, get exposed and electrocute someone.

[-] kn33@lemmy.world 4 points 6 days ago

Is that less likely to happen if the pole is knocked down instead of the line dug up?

[-] abfarid@startrek.website 3 points 6 days ago

No idea, that's what I've been told, but Japanese engineers usually know what they are doing.

[-] stebo02@lemmy.dbzer0.com 2 points 6 days ago

Are they really safer in an earthquake though? Those poles could fall over and people could get caught under the cables, worst case while they're still under high voltage...

[-] HubertManne@moist.catsweat.com 7 points 6 days ago

Yes im encouraged by seeing them use those machines to put things in the ground. I had not realized how effiicient it had gotten. May be cheaper than the poles hanging now.

[-] SomeoneSomewhere@lemmy.nz 5 points 6 days ago

Still about a 10x cost difference, plus (particularly on transmission lines) there's issues with extra capacitive loading.

[-] HubertManne@moist.catsweat.com 1 points 6 days ago

so 10x more expensive for buried? if so I am really surprised because those machines seem like less than having the cherry picker and such. Granted though I think it only really works were you have long spans of soft soil. If its all concrete your not going to be able to do it. I would hope in the concrete thing though that tunnels would be available for this infrastructure.

Investing on your country would be connecting more people to electricity not make the sky look better

[-] vzq@lemmy.world 2 points 6 days ago

The sky looking better is just one thing. No more blackouts when there’s winds or thunderstorms or just stray branches is the real perk.

Interestingly, underground lines aren't feasible in my hometown because of how close the water table is to the surface. Any trench deep enough to bury cables in would have to worry about flooding with groundwater or saltwater in some places.

The water table is so high that not only are there many places where basements would flood 100% of the year, but the majority of homes still have septic tanks instead of town sewage lines, and you can find houses where the lawn has been raised up with 3 or 4 feet of concrete to raise the septic tank to comply with modern regulations to avoid contaminating the groundwater supply.

I’m 4 meters below sea level. We don’t have basements because the buoyancy of the empty space would cause the houses to literally float on ground water. But we do have buried power lines.

You are being lied to.

[-] phoneymouse@lemmy.world 2 points 6 days ago

Thanks for the idea, but have you considered spending it all on bombs instead?

[-] JackbyDev@programming.dev 1 points 6 days ago

My house has buried lines! ...from the street to the house only... 🥺
