pH7.0 (3799) writes "From this Toronto Star story: http://www.thestar.com/article/175800 "there's simply not enough lithium available in the Earth's crust to stick a lithium-ion battery in the world's 900 million cars, and at the same time expect the auto market to grow. It's just not sustainable." Is this true? AFAIK there are more Lithium in the earth's crust than Tin or Lead. May it's still not enough? OTOH, that story try to plug "Zebra Battery" but fail to mention "Molten salt"..."
