NEC, the Japanese electronics manufacturer, recently unveiled a new concept phone that uses fuel cell as power.

The handset is apparently named NEC Flask Phone and, at a first glance, it looks like a giant lighter that Bigfoot might really love (if he exists and if he smokes). At a second glance, things seem a bit more serious, as this device is said to pack some sort of a touchscreen that also has the role of a keypad. The phone has a transparent case that allows users to see how much fuel is consumed, thus knowing when to recharge, and it's intended to be a device that perfectly integrates advanced technology and simple but elegant design.
