Is the micrometeorites fact about the value of gold and platinum fake? I think it is and don't find that value in the link.

Regarding power line conductors, we previously had lines with copper conductor and a hemp rope core. I think it dated from the war when there was a copper shortage. There was also a line with a bronze core and copper (I think) wound around it. I believe all of it has been replaced with aluminum conductor, steel reinforced cables. I'm not 100% certain there isn't still some out there, though. I'm certain there are still copper lower voltage lines. There's one near home.

Rope?! That's crazy. What about fire, rodents, rotting? I am always amazed when the state of the art in engineering is the least worst thing that works. When it's not a split washer.

I made up the bit about gold and platinum. Then I had to fact-check it because you never know.
