batteries!? shortage of lead!???

There is very little lithium carbonate in the US. Most of it comes from China and South America. It is the primary component in lithium batteries. Lithium is non toxic and used as a mood-stabilizing drug in the treatment of bipolar disorder.

I was invested in a Lithium battery company (A123 Systems) until Obama killed it by trying to make them into a car battery manufacturer. The Fisker Karma was their first car but they botched the order and went bankrupt. A123 made batteries for power tools and were coming out with a 12V starter battery that weighed around 18lbs. Now a Chinese company owns part of them and the rest was sold to Johnson Controls.
