I keep seeing articles about all the wonders of Graphene (and its derivatives, like Graphene Oxide). When will I actually see any of these wonders affecting my life?
Yes. Previously this role was played by carbon nanotubes.
Even supposing we work out a way to manufacture graphene cheaply, it seems to me that there are lots of technical solutions to problems out there which remain undeveloped for lack of a viable financial model (or simply bad luck I suppose).
