I agree. It's on the way. Wasn't too long ago that terms like "lithium ion" and "nickle metal hydride" were unheard of to the common consumer. It takes a lot of energy to manufacture those batteries ... and recycle them when they are used up. You have to factor that into the equation. These batteries have high energy per unit volume but they cost a lot of money because it takes a lot of energy to produce them.
