KDDI minimalist concept phone captures solar rays, doubles as dark matter

We've uncovered more ecologically friendly goodies from KDDI's Design Project. The latest is a concept device is aptly named the GEM and looks as though it was carved out of a single slab of obsidian with an oddly organic form factor.

The creator, Japanese designer Takumi Ota, doesn't offer much in the way of details in terms of how the handset would work other than to detail its ability to charge itself via a set of rather sexy solar panels. It's a sure bet that if Blackberry's looked like this, there would be less debate among the iPhone refuseniks about what smartphone to get.
