We've been hearing about how great graphene is and how it will revolutionise everything under the sun for the better part of a decade now. My question is simply, when will we see an actual product using it? To my knowledge none exists, and I haven't even heard about any being less than a few years away. Cam someone who is knowledgeable in these matters shed some light on this??
