Re: [EVDL] Toyota breaks China dependency w/ efficient cheaper lighter electromagnet

Hmmmm. Induction motors eh... those haven't been around for 100 years... I
actually have one in my EV already....

And, why would I be worried about limited supplies of rare earth metals
being a problem for electric cars if I don't worry about the limited
supplies of oil being a problem for ICE cars. It seems somewhat like a
scare tactic against electric cars, and not a very well thought out one for
anyone with a brain.
