Graphene. If youve never heard about it, dont worry, a lot of people havent, because its really only been discovered relatively recently, and most of the truly interesting news about it has been in the last year. The amazing thing is that weve actually been using it for centuries, in the form of the common pencil. Graphene is a form of carbon, much like carbon nanotubes and other fullerenes, with one major difference. While fullerenes are 3D structures of carbon atoms, graphene is a flat sheet. Its a 2D lattice of carbon with bonds as strong as diamond. Its this sheetlike nature that makes it so useful in a pencil. As you write, individual planes of graphite are sheared off the end and deposited on the paper. Those individual planes are pure graphene.

Imagine... one RISK chip at 30 Ghz and a FPGA on a co-processor, all on your cell phone/pda.

Many people are unaware that pencils are manufactued with a round cross section. But during shipping the graphene can cause the pencils to take on the more familiar hexagonal shape.
Pencils with low graphene content, or high colored pigment content, will remain round.

Can you cite your source on that info?

Can you cite your source on that info? Sorry, no. Like I said, "Many people are unaware...". And I believe there are national security issues involved as well. Shape changing is very serious business, even for pencils.

Data encryption had better get a whole lot stronger. Brute force attacks will be very easy with this kind of power.
