BTW... the short version is
1. that they are finding cheap ways to make it from waste products like methane from trash and old tires and coal ash
2. and the killer app might be concrete
QuoteYet if less than 0.1% by weight of graphene is added to the mixture, concrete ends up 30% stronger. And stronger concrete means less of it is needed, with a consequent reduction in CO2.

The only thing we use more of is water.

"The shift is still early, but on test slabs, factory lines, and university campuses, graphene concrete is already rewriting the assumptions that have governed construction for decades."
Very useful for everything. If 3D printed houses catch on this is coming along at the right time.
