GB was struggling to share the luv in Vegas, couple of slides presented that made his pitch look rather limp:
But ya have to give GB credit for persistence, off to Hainan next month for another go.
Another major area Dy deletion that hasn't got a lot of attention is motor design, Surface vs Internal NdFeB placement:
"The designs are different when it comes to thermal management, as well. In SPM designs, a significant amount of heat is generated in the magnets, which can cause demagnetization. Adding a small amount dysprosium to the magnet material can significantly enhance heat tolerance, but dysprosium is currently expensive.
IPM machines with distributed windings typically do not generate a significant amount of heat in the rotor—roughly 90% of the motor losses tend to occur in the stator, which can be easily cooled by heat sinking, oil cooling, or watercooling."
Not so hard to figure which way PMM design has been headed...................
