I find this interesting to think of how batteries in the very near future will change. I imagine this may end up going the same direction as computer transistors and the power of batteries will begin to grow exponentially. I can see a time within 20 years where (given the assumption that big corporations don't use stall tactics) battery power could be woven into fabric and recharged by the very molecules in the air.

I can't wait to see how power output changes.
