Cosmic abundance isn't the important thing. Abundance on earth is.
All I know is that current world production of lithium ion batteries is enough to make perhaps 300,000 batteries of the Tesla type per year if all that material went into them.
That's not much on the wide scale of things.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
