Graphene has been touted to be a game changer for a long time and it hasnt come to fruition. While its a miracle material it is just not cost effective to be used in mass quantities, eg cement (huge market but margins are slim and while amazing in cement its not economical)

Then you get into the discussion of what Graphene is, single layer, multi layer etc. TLG have been trying to commercial graphene for years with only small achievements made commercially. What happend to the ship with graphene coating? If it worked wonders im sure we would of heard by now.

To me the real value of TLG's graphene tech is its potential ability for Talnode-Si, from my limited understanding they plan to coat the silicon in graphene which i assume prevents the expansion of the silicon when charged.
