It is storage that is a fair problem- but everyone in these videos act like batteries are made of fairy dust and good will.People worry about nuclear waste,but what about the vast amount of toxic waste that all these batteries will generate at the end of their lives. I suppose they'll come up with a different colored recycling bins for them so everyone can feel good about themselves when all the batteries are "recycled" into unregulated toxic waste dumps in third world countries like they do with plastic right now.
