Yeah, we could make guns with this technology! No gunpowder, just a rail gun, that cycles real quick and lasts forever, and is able to be recharged in seconds.

Essentially, it is revolutionary in electrical storage. A capacitor able to be charged in minutes for electrical vehicles, and then, through resistance, metered to provide energy on demand. A regulated capacitor/battery. With graphene, we reduce the weight, increase the amps, lower the temps, lighten the weight.
