Off subject but they found dangling a long cable into the atmosphere from low orbit or whatever they could generate a lot of electricity, the cable broke off after a while though when they tried it.

Well we already can do directional sound, perhaps we can find a way to do focused directional magnetic fields, and then lift things into space without using cables? Obviously, I know it's entirely different mechanisms. Even using this to make electric motors way more powerful or something could be an application.
