I agree completely. It is very early in the development of graphene products. Early adopters always pay the highest price, then existing methods are improved or new methods found that lower costs. But it sure seems like a no-brainer to make graphene out of waste cooking oil if you can.

Your comments on inventions not seeing the light of day struck a chord.

"Making/producing/discovering something in a Lab setting and then trying to ramp it up to a production setting is where the issues always are and why the vast majority of items made/discovered in Labs never hit the markets."

This sounds so familiar. Maybe it's just what chief et al have cautioned about ZEN?
