Ahead of John McCains game but Lithium Ion is not the future, it still creates pollution and lithium ion batterys still have half lifes and all though they can re-charge they will still need to be replaced at some point. Like any lithium ion battery they will only last so long, the worst part is the costs of Lithium Ions. Not sure if you noticed but there not the cheapest things in the world. We mine as well just cut holes in our floor boards and "Flinestone" around town until they develop hydrogen or wind more.
