A new technology has found it’s way to transmit information through light instead of wires. This allows to transmit 8 terabits of data per second, which is the equivalent of around 5 000 high-definition movies, per second.
So far, the biggest advantage of this technology is his power consumption, which is 100 times less than on wire. Although new technologies as such takes time to hit the market, this one as bigger chance to hit it pretty soon, as IBM researcher Clint Schow explain:
These aren’t theoretical experiments or chips sitting in unique conditions in a lab, but rather chipsets that could hit the market in the next two years. The innovation lies in the fact that we are making optics with the same kind of packaging as electronics.
MSI as recently developed a working concept of a fan which runs from the heat produced by the processor. It is based of Stirling Engine Theory
which works almost like a car engine would. This new “green” technology should be able to reduce the consumption of your computer electricity, but not by much since fans are a small part of the actual electrical consumption. But reducing little by little is better than nothing, isn’t it?

You’re not one of those old-fashioned folks who still writes down notes by hand, are you?
If so, rest assured that you won’t have to give up your pen and paper anytime soon. You can, however, make your pen a little smarter than it used to be.
The just-released Pulse Smartpen from Livescribe is a huge advance in note-taking ability. Sure, digital pens that use handwriting recognition software to transcribe your writing into digital form are nothing new. But the Smartpen is even smarter: it records audio while you write and syncs it to the words you’ve written on the special, dedicated paper. Want to play back the recording? Just tap that spot in your notes and get a playback of the audio heard at that particular time.
The device is marketed mainly for journalists and businesspeople. But at $150 it could even find a niche among college students. Many students record their lectures, but the task of hunting through the audio to find a particular point makes these recordings of little use. The Smartpen could change this. Now if they could only program it to take exams, too…
You kick around a lot of numbers when choosing a computer, but silicon chip size is probably not one of them. However,this is a key figure that determines all the important numbers that you do care about. Computer speed and memory are determined by how many silicon chips you can pack into a small space. The more silicon chips you have, the more speed and memory are at your disposal.
To be precise, it’s not the size of the chip itself, but the feature size that is important. This is the size of the individual electrical components that are crafted out of the silicon. Current computers often use silicon chips with feature sizes of 65 to 90 nanometers. That’s several times smaller than one of the hairs on your head!
A big question in modern computing is how much smaller we can get. A quirkly principle known as Moore’s Law predicts that the number of features that can be squeezed into a given area doubles every two years. But we can’t keep halving the feature size forever — eventually we will reach a limit. Why? Once we get down to the size of bare molecules, we can’t scale down any smaller. And quantum physics effects will probably interfere with smooth operation long before we reach that level.

Hear that loud whirring sound from your laptop? That’s the fan working overtime to try and cool down your overheated machine. This massive heat dissipation is caused by many culprits, and the main one is your hard drive.
What’s on your hard drive? It’s a bunch of spinning disks, and it’s those that drain so much power. But several recent advances in Flash technology innovation mean that the spinning disks may soon turn into a relic of the past.
A few years, the introduction of the NAND flash memory looked like it would signify a revolution in computer storage, with a lot of memory packed into a small space. But there was one drawback: data transfer rates between devices were sluggishly slow.
Now, a partnership of Intel and Micron has come up with a potential cure for the bottleneck. Their joint venture recently released a new flash drive with data transfer rates up to 200 MBps (reading) and 100 MBps (writing). That’s about 5 times faster than traditional flash technology.
