Shmitt - Thanks for that article. I've thought about it a lot since you posted it. My impression is that thier process (separating carbon atoms from methane and depositing them single layer - the essense of graphene) is far more direct and likely cheaper than any process conceived of with even pure carbon flakes, powders, chunks etc. Seems only vaporized carbon could be more direct - but what extreme temperatures would be needed for that?

I think ZEN has tremendous potential for many different, highly profitable products. Don't know whether graphene is in the mix.

Cheers
