Mike writes to tell us that Samsung has released their latest green gadget, a solar-powered mobile phone. The "Blue Earth" phone has the entire reverse side covered with a solar panel, and the body of the phone is made from recycled water bottles. "The device is set to be energy efficient, with a new user interface making it easy to activate the phone's energy saving mode. It also includes a pedometer, and CO2 emissions calculator, and Samsung is aiming for minimal packaging made entirely from recycled paper. Samsung is clearly throwing the gauntlet to all phone manufacturers, and we hope to see solar cells integrated throughout the rest of their line. The phone will be unveiled on February 16th at the Mobile World Congress in Barcelona."
