Ann: Operational Update Graphene Production and Mining Activities, page-90

Had a long response to this.. but then my browser crashed.

Long and short is that yes the rolled sheet is commonly accepted, but a single rolled sheet is inherently limited.

I shouldn't have said "I have no idea" but more I have no idea what they are proposing for their 3D SC design

If this SC is as ground breaking as claimed, then something in the design and fabrication must also be as ground breakingly different.

Also thanks to @jumpstart , @downsyde , @spid81 and others for the continued debate.
As long as people don't get too emotionally involved and are willing to question what you read from each contributor there's a lot of good stuff in these threads... along some tripe.. but I won't go there in any detail
