Graphene 'spin computers' could bring smaller gadgets

Graphene spin computers could mean big improvements for your PC and gadgets.

As reported at physorg.com, University of California, Riverside physicists have made breakthroughs in developing graphene-based “spin computers”. A spin computer would allow for huge storage capacity using a fraction of the power consumption of current electronics. This is accomplished through polarization of electrons -- the spin process actually gives each a directional orientation, up or down. A spin computer would maximize usage of this state of materials to store more data, perform faster, and generate less heat than standard electronics.

What this means is coming down the pipe we’ll see exponentially larger hard drive capacity in smaller and smaller packaging; hard drives that use less power and generate less heat with every iteration of the technology. Laptops will get lighter, last longer on battery and not scorch laps. Mobile devices will be able to store your entire media library (well, your approved media library).

Everything and everyone would benefit from this technology in some fashion. From a limited personal perspective, having to be tied to the Cloud will be less important because you’ll be able to carry it all with you in a tiny package, and by that same token from a large business perspective today’s vast data centers with endless racks of disk arrays will be able to be reduced to something more fiscally and energy friendly.

Those are two conservative examples - imagining refinement of the technology brings to mind near limitless storage capacity devices micro-chip sized. Our brains are fairly simply organic computers -- Johnny Mnemonic doesn’t seem that far fetched anymore.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
