This is a great idea. The device is able to generate energy from any kind of noise and that energy could be used for virtually anything, for example street lamps. The designers that worket on this project are: Jihoon Kim, Boyeon Kim, Myung-Suk Kim, and Da-Woon Chung. One Sonea unit measures 450mm by 450mm by 80mm and weights 7 kilograms. It is able to convert 30 watts of power per decibel of sound that it catches. The device is made using polycarbonate elements, ABS, and some other components. Let’s say that one airplane liftoff generates a noise around 140dB. Thus, using Sonea, it would be possible to produce about 240kW of energy. Considering about 500 airplanes each day, it would be possible to generate about 120MW of energy. In one year Sonea will be able to generate the amount energy that is equivalent to energy produced by 8000tons of oil.

Sony Ericsson recently unveiled its new XPERIA X2 model that boasts a 3.2-inch touchscreen and an incredible 8.1 megapixel camera.

The dimensions of this model are about the same as its predecessor X1, but the current smartphone is lighter and its developers decided to redesign the keypad so it would look like a netbook one. You can reveal the keyboard by simply sliding out the phone’s upper portion.

The 8.1 megapixel camera is probably one of its most interesting features. XPERIA X2 from Sony Ericsson has 14 preloaded and 16 more downloadable custom panel interfaces. The gadget is also meant to present for the first time the Windows Mobile 6.5 operating system.

Now you have the opportunity to observe an amazing ultra mobile computer concept called Slider. You can use it for everything you need 24/7.

The device has a functional 9-inch touchscreen display plus a full QWERTY keyboard at your disposal.

You can reveal the keyboard by flipping the screen. Using 1GB RAM together with a 1.5GHz processor you have the ability to run VOIP video chat and take advantage of perfect mobile video streaming.

Due to the fact that the mobile computer was developed to be ultra compact, the battery life is rather short, not that it’s bad or something, it can still offer you 4 to 7 hours of operation and I must admit that with a design like that, all other features simply fade away.

Those of you who enjoy photography will definitely appreciate these cool models from Casio. The company introduced two types of its new photo printer: the PCP-1300 and PCP-300.

Both photo printers create accurate postcard-sized images, plus they are quite compact, measuring about 251×130x151(147) mm.

The first model includes a 7-inch LCD touchscreen monitor with 480×234 resolution. It is also compatible with a wide range of memory cards and picture cards. The PCP-1300 weights only 2.3kg and its price is $ 577.

The second model is somewhat lighter, weighting 2.1kg and featuring a smaller 3.5-inch display that has a 240×320 resolution, but it is also less costly, around $ 420.

Both models have a QWERTY keyboard and boast a modern design. It is expected that the printers will be introduced on September 11.
