In fact, there isn't nearly enough known mineable resources to provide more than a tiny fraction of the population with a Prius. So either there needs to be some HUGE deposits found QUICK, or the electric "revolution" is bound to short circuit.

At a recent presentation in Berlin I took your table one step further and calculated that 19,000 metric tons works out to 3 grams per capita based on a global population of 6.8 billion people. People's eyes always glaze over when faced with large numbers and I found that taking it down to a per capita level raised a lot of eyebrows.
