Didn’t know this: “Because of its electricity-conducting capacity, aluminum was used as the cap of the Washington Monument, completed in 1885, the tallest building in the world at the time. The non-corroding metal cap was intended to serve as a lightning rod peak.”
I’d heard aluminum referred to as “solidified electricity” which was intriguing so I looked it up; but it apparently just means the smelting process requires a lot of electricity — the term is a fair description from a cost perspective.
