Samsung unveils their Blue Earth “eco” friendly cell phone. This cell phone is taking the “eco” friendly term to a whole new level. The phone casing is made from PCM, a type of plastic made form recycled water bottles. The phone has several eco modes for efficiently adjusting screen brightness, back light duration and Bluetooth usage. There is also an”eco walk” built-in pedometer application to tell you how much CO2 emission you’ve saved by walking,running or even cycling instead of driving. Last but not least, on the back of the cell phone is a solar panel that will allow you to make a call anytime the sun is out.
