gamechanger - supercapacitors

supercapacitors have the capability to immediately ease the current choke point to massive renewables roll-out - battery tech. as this short film shows batteries are high storage + slow charge & discharge; capacitors are low storage + fast charge & discharge but graphene-based supercapacitors combine the best qualities of batteries and capacitors and are high storage + fast charge and discharge. if successfully industrialized (and they will be because they are cheap and easy to make) this can give us the super renewables smart grids we need for green power and transportation...
