Introducing Graphene, a carbon based super capacitor that charges like a capacitor but could discharge like a battery. It has tremendous structural strength but is extremely light. The cost to create it, at this point, is extremely low, while its potential as the battery of the future is high.
Oh yeah, and this “super capacitor” is made entirely of carbon. When you’re done with it you could throw it in your compost.
Modern batteries are heavy, environmentally unfriendly at both ends of their life, are made with things we (in the US at least) have to import. Graphene is made with ordinary carbon, is abundant, and offers us the potential for exactly the opposite.
It has the potential to change the world. Here’s some video
