The entirety of civilization seems fairly well and dedicated to one-upping each other in the "green" department, and Samsung is looking to up the ante once again by stating that "blue is the new green" and putting out the new Blue Earth solar phone to prove it. Sadly, the Blue Earth isn't quite ready to go -- currently it's only to be seen in non-working mockup form, though the hardware is certainly looking good. Samsung's showing off its eco-packaging and built-in energy-saving functionality, including an "Eco Walk" function to let you know how many trees you save by walking places. The phone itself is built from castor bean extract and recycled plastic, and Samsung claims the integrated solar panel saves up to 34.6% of the battery's energy. They're also showing off a hand-crank generator, external solar chargers, and even a solar-charged stereo headset. It's clear that Samsung isn't just playing lip service to green (or blue, as the case may be) but at this point in time this technology is likely to act more as a gimmick and promise of things to come than a truly life-changing device.
