If buyers really do plan to line up to buy electric vehicles, even before the government forces them to, automakers had best figure out a way to make them affordable not just to buy, but to build.

We all know battery packs are expensive (with ingredients clouded by child labor and environmental issues), but batteries are only part of the equation. While simple in operation, electric motors are nothing like the aluminum or iron affairs under the hood of your dad’s Buick Enclave. There’s a lot of metals you’ve never heard of in a permanent magnet AC motor.

Toyota, which wants to be an electric car bigshot, just figured out a way to make a cheaper motor.

Metals found in hybrid batteries, diesel fuel and headlight glass could again be subject to China’s ever-changing rules for rare earth exports.

On Wednesday, Molycorp announced that it would be suspending its mining operations of rare earth metals in California, but keep its mines in China and Estonia open for the time being.

The company, which went public in 2011, has fallen on hard times. In June, the company filed for Chapter 11 bankruptcy protection and slowing demand in China isn’t helping. However, without a mine in the U.S., much of the rare earth metal mined in the world could be under Chinese government purview, and that’s not good.
