General Motors Corp (GM)

Batteries (and what they are made of)are what is unique to and electric car, not copper use. You current car is already full of copper(*starter motor, alternator, wiring, electronics)
Real copper use comes from heavy industry where motors and generators can weigh hundreds of pounds and copper pipes stretch for thousands of feet.

The idea that GMs "Volt" will be a roaring success is very premature. GM is way behind the curve in that department and prone to lots of over inflated hype.
