This is already done, just not at great scale. https://en.wikipedia.org/wiki/Superconducting_wire https://en.wikipedia.org/wiki/Superconducting_wire For detailed information about one actually built and used: https://www.furukawa.co.jp/review/fr035/fr35_04.pdf https://www.furukawa.co.jp/review/fr035/fr35_04.pdf The enthusasiam is nice but there's a lot of NIH going on. I'd encourage people to research subject matter before thinking no one else has had similar ideas before. It's "easy to make" in a sense, but the yields are insanely low (think 1/1000) or less of input materials. This indicates there are some variables that either are not controlled for or cannot be controlled. That being said, its still early but it looks like LK-99 is not what we typically think about when we think of a super conductor. If we can figure out a good way to make it (with time we likely will), it will still have applications, just likely not high power transmission ones.
