Elon has said in the past that he wanted to add solar panels to Supercharger locations, so the logical assumption is the addition of Tesla Energy Powerpack. Some discussion questions. 1. Will Tesla Energy make the packs visible in order to market the products? 2. Will some of the lightly used Superchargers produce more energy than they consume and become profit centers of energy? 3. Can Tesla somehow design the Powerpacks in such a way that they can output higher charge rates than the utilities can provide? Sort of a "super capacitor" if you will.
