More on Rare Earth Motor Substitutes

You know, it seems that unlike the doomer position (where substitutes can't happen because oil is irreplaceable) substitutes seem to be popping out of the woodwork.

Yet another substitute for rare-earth magnets by a Silicon Valley based company:

Novatorque's design uses ferrite magnets and some innovative engineering to produce a motor that functions under similar operating conidtions to neodymium based magnets but without the need for rare earths.What it does is make a motor more efficient by modifying the shape and positioning of the magnets to improve magnetic flux.

Now the interesting point about this is that this technology could *also* be applied to rare earth magnets thus reducing the usage of rare-earth minerals and therefore magnifying the utility of existing reserves.
