Energy weapons are still mostly science fiction right now. This changes that. Energy storage increases by an order of magnitude and with no resistance you can charge and discharge batteries instantaneously.

Probably some other really interesting uses, but energy weapons is what we'll figure out first. And not just giant ship mounted rail guns—if true this will start a new arms race for personal handheld weapons. No more gunpowder. Think rifles with almost no maintenance. Outrageous magazine capacity with shot capacity limited only by energy storage capacity… which can easily and quickly be resupplied if you are behind a supply line.
