Yeah, I hate to give communist china (always small letters) any more of an advantage, as they develop their cheating free enterprise methods. The rare earths are bad on the environment, specially in communist chinese (always small letters) mining & productions.

Do you think any of the alternatives in Europe, to make less intensive REE magnets or superconductors or Great Britain's ferrite magnets have reasonable directions toward efficient production & use?

I love the idea of the gearless wind turbines, specially in huge applications.
