Back in May, 2013, I wrote about the potential for using graphene to desalinate water. If graphene has all these miracle properties, watch for more economic growth and more change as entrepreneurs find less expensive ways to produce and use high-quality graphene . Wow!
Update: Jack recommends the Wikipaedia link to many of the potential uses being touted for graphene. Also, see this for the possibility that even more materials with even more desireable properties might be in the pipeline.
