LG, Samsung develop solar-powered cell phones

Monday, February 23rd, 2009

Most people had long been waiting for a sharp cure in cell phone technology to use some renewable source of energy. This has been proved by Samsung Electronics and LG Electronics who would soon unveil their prototype handsets which can be charged through solar panels built in the cases.

The cell phone from Samsung called the Blue Earth is designed as touch screen model that is designed with curved corners which looks much like their previous well curved pebble model. Samsung continued with the environment theme saying that the phone has been manufactured from specific recycled plastic and it does not include any harmful substances like phthalates, brominated flame retardants and beryllium. There are solar cells on the cell phone which occupies most of the rear case of the cell phone.

However, LG did not provide many details about their prototype cell phone, but a few pictures from LG Electronics would show you what seems to be the version of their KF750 Secret handset like, similar to the Samsung as this model from LG also comes with solar cells that cover most of the rear casing of the cell phone. These two cell phones from the two huge electronic consumer manufacturers were declared almost at the same time by the respective company in South Korea this month. However it has been observed that in both these cell phones the solar panels do not prove to offer enough power to operate the cell phone directly and so they are basically used for recharging the standard cell phone battery that is built into the device.

Now, you might even be thinking that these new cell phones with an innovative technology might be meaning an end to all the charging devices. As the answer here seems almost certain it is actual not, at least initially. Samsung has said that their Blue Earth cell phone is packed with charger but they also added that the device is an energy resourceful device which draws just about 30 milliwatts when in its standby mode. However according to LG, they hope to commercialize these solar charged cell phones when they have a model which offers at least 3 minutes of talk time after being charges for around ten minutes.

Therefore, in the shallow limits of a bag or pocket the phones will not be capable of charging and so the users will need to make sure that they are frequently out in the sunlight. Additionally as the solar panels are fixed at the rear side of the device, they should be placed faced down for highest efficiency which can lead to scuffing and scratching of the display.

Regardless of these few drawbacks, the development of these cell phones means that are companies thinking about designing and manufacturing eco friendly products or they are thinking about environmentally conscious people along with the increasing market for green and earth friendly products. However, both the companies have still not offered any timing for the prototypes to become commercial devices and also about their pricing details.

ASUS have almost reached double digits in the number of their notebook variants that are launched. Additionally, the ASUS EeePC 1000HE overthrows the MSI Wind as just the pack of pint sizes notebook wannabes. Something that puts it up is not just its first use of Intel Atom N280 processor but also its revamped keyboard and pleasingly tucked away six cell battery. This EeePC 1000HE has been the new choice among editors in the category where price compassion is para mounted is because it delivers all of these at a reasonable price.

With its design the EeePC 1000HE resembles a vast majority of notebooks with its glossy coat and limited colour variations. Your only choices are among its two colour variations navy blue and black. It weighs about 3.2 pounds which can be heavier than Acer Aspire One, the MSI Wind which is 2.6 pounds and 2.9 pounds NC10-14GB notebook.  There is a frame designed around the six cell carriers which conceals the batteries so that it is flush against the base. In fact the E in EeePC 1000HE actually represents its extended battery which is a massive improvement on the battery over their previous models.

As you open the lid the caps on barreled ends are timed with steel which also include a brushed aluminum enclosure that houses the mouse touchpad and mouse buttons where both offer sharp contrast in black interior. The mouse buttons of 1000HE are substantially larger compared to Aspire One and MSI Wind which look like they are wrapped around the front bezel in the laptop’s center. However similar to other laptops the EeePC 1000HE also uses a 10 inch LED widescreen with great resolutions. Additionally the keyboard of 1000HE is completely refurbished from 1000H notebook. The keys on it are again much similar to those on Apple MacBook 13 inch and Sony VAIO VGN-Z590.

The EeePC 1000HE also does not have any exclusive features over other notebooks like it also sports a webcam, three USB ports, a 4-in-1 card reader, VGA-out, 802.11n Wi-Fi and Ethernet port wit other standard notebook features. However the only real advantage is the in built Bluetooth it features. It includes 160 GB hard drier, but it does not integrate an ExpressCard slot like most of the other notebooks have, which it also does not offer in built mobile broadband.

The best thing is that, EeePC 1000HE is the first laptop to feature 1.66 GHz Intel Atom N280 processor. This means that for a benchmark test or even when really using it you might hardly find any performance difference between the EeePC 1000HE and other systems like Aspire One and MSI Wind. Additionally ASUS have also added their software based over clocking feature similar to their other models which controls the speed of CPU. It lets you switch between different modes like Auto, High performance, super performance and power saving. However, the real advantage in transitioning to N280 processor is the reduction of motherboard space which slims down other form factors and potentially reduces the cost.
