The army is already taking advantage of this energy and it makes its soldiers to carry on in their backpacks batteries of 10 kilos to supply their electronic equipments. To the general public this save of energy would be useful to recharge cell phone batteries or iPods (about 4 watts), or to recharge personal medical devices as pacemakers, and audio implants. However, for now researches have not been able to recover this energy and transfer it to the gadget to be recharged.

In the city of Toulouse, France, there is a sidewalk in downtown that saves the energy of the approximately 10,000 daily walkers that step on one of the 10 equipped flagstones, which are pushed into the ground about 4-5 mm. This vertical movement (pressure and release) is transformed by a generator. Each flagstone produces between 3 to 6 watts, which allows to light during night a LED lamppost during 3 or 4 hours.

The features of this tablet are quite average in comparison with other tablets in the market  except the processor that this time is a 1.5 GHz Intel Atom and the screen size is 10.1 inches (which seems to be the measure which is running to impose) and resolution 1280 x 800 pixels. For the rest of features include 2 GB of RAM, 2 megapixel camera for video conferencing (we miss a second camera already found in other models), USB and MicroSD slot.

The Lenovo IdeaPad P1 will have a operative range of 6 hours (somewhat limited) and will be available with 32 or 64 GB of storage capacity. There will also be models with WiFi or WiFi +3 G. Along with the tablet comes a charging station and will be available optionally a pen or stylus to use on the screen.

The design of the tablet is similar to that seen in other models, measuring 279 × 14.5 × of 184mm and a weight of 810 grams. Perhaps most striking is the orange color of the casing at the back which gives it a touch of color that is always appreciated.

The BlackBerry 9810 is a small update of the first Torch in the market, and as that combines a 3.2-inch touch screen with resolution 640 x 480 pixels and a sliding QWERTY keyboard. Inside are a single-core processor at 1.2 Ghz, 768 GB of RAM and 8 GB of storage capacity, but also accepts MicroSD cards up to 32 GB. The 5 megapixel camera has LED flash and can record HD video at 720p resolution.

On the second of the models, the BlackBerry 9850,  we would be facing an entirely new model, since the physical keyboard disappears, becoming a full touch screen terminal. That is why the screen is increased to the 3.7 inches, which is the largest size used by a company phone so far. The processor is the same 1.2 Ghz, a little short if you want to try to compete with dual-core processors that have the most outstanding models already existing on the market.

But it is very interesting to know numbers, and that is according to Samsung, the phone has exceeded 3 million units sold. What is really striking taking in account that it has achieved these numbers in just 55 days since it appeared on the market.

Thus becomes the fastest phone has been sold in the history of the Korean company, and taking into account the price at which we move is even more valuable. A Galaxy Samsung S2 has a new owner every 1.5 seconds.

The original Samsung S Galaxy took 85 days to get to the same figure, a figure also take into account as the first major Samsung Android bet. We’ll see how long it takes the new phone to reach 10 million phones sold.

Samsung reports that the UK has been the bestselling country for the phone, and the firm has stayed for 17 weeks being the main selling phone company in the country. Another major market like the United States still waits for its appearance with major carriers.

The new Windows interface in Internet Explorer 8 has 10 engines to run Web applications. And the look is completely underground, but takes a look at how to present different applications simultaneously on screen, being able to modify the workspace of each of them by touch and dynamics.

With respect to hardware specifications, Microsoft reports that it will be very different from Windows 7, in Intel options (from Atom) and AMD. About ARM versions will also know that (Nvidia, Qualcomm and Texas Instruments), but has not made any progress in this presentation. With respect to tablets, the CEO of Acer and informed us that Microsoft was getting hard on the issue.

No details have been revealed about its introduction in the market, but we are summoned to the month of September in which Microsoft is hosting a conference for developers called Build, in which we will know the system in its final state, in addition to its final name .

In addition, the Android operating system expands the view beyond what we mean by pure tablet, which would be models with Android 3.0 and up. The P4D Nvsbl v3 goes precisely in this idea.

The first tablets had very resistive and affordable screens with poor quality version of Android.

This P4D v3 stays true to the previous version but with improvements in processor (ARM Cortex A9 at 1.2 GHz and graphics chip MALI-400), the addition of Bluetooth connectivity and finish with the best grip rubber material for the rear housing. Also the operating system is a big change with the arrival of Android 2.2 Froyo.

The rest of the tablet features are identical to the previous model: 512 MB RAM, 8 GB of internal memory expandable via micro SD, mini USB 2.0 port and mini HDMI output . Its thickness is 13 mm and weight a little over 300 grams. The resulting performance is quite good.

Design -we have to mention- lacks of the usual controls on Android phones, because Nvsbl does not implement a physical touchscreen, at least in the usual way.
