The substance found in pencils will speed up our computers one thousand fold

from h+ Magazine:

Graphene. If you’ve never heard about it, don’t worry, a lot of people haven’t, because it’s really only been “discovered” relatively recently, and most of the truly interesting news about it has been in the last year.

“We’re talking about that smartphone in your pocket having a thousand times the computing power of your desktop PC, but using no more power.”

MIT looks at “Computing beyond Silicon”

from MIT’s Technology Review:

It is inevitable that eventually Moore’s Law will fail–at least for silicon technology. Further miniaturizing silicon transistors to fit more of them on a microchip will become impossible, or at least too expensive. Researchers are anticipating that day by developing alternative materials such as gallium arsenide, graphene, and carbon nanotubes.

The hope is that transistors made from these materials will be smaller, faster, and more energy efficient than anything that could ever be made from silicon. “We need to add more materials to the toolbox,” says Michael Mayberry, director of components research at Intel.

Coming soon: Glowing walls made from graphene

from DVICE:

Scientists in Sweden and the USA say they have developed lighting panels using the wonder material graphene, which one day could make the basic lamp redundant.

The material can be fashioned into large energy efficient flexible sheets called LECs (light emitting electromechanical cells) that can cover an entire wall or ceiling, filling the room with an adjustable and even source of light.

We’ve seen how OLED technology promises a similar approach to lighting, but the scientists say the graphene panels are much cheaper to produce, and don’t contain the metal alloy indium tin oxide that makes OLED panels tricky to recycle.
