Samsung announced the Blue Earth, an environmentally-minded phone made from recycled materials that can use solar power to charge the battery. The solar cells are built into the back of the phone. The Blue Earth, which was designed to resemble a pebble, has a touch screen and custom-made user interface for input. It can go into a low-power “Eco-mode”, has a built in pedometer, and will let users know how they are reducing CO2 emissions by walking rather than driving. Its charger has a 5-star energy efficiency rating and draw very little power.
