Nokia E-Cu Concept Phone Charges In Your Pocket Thanks To Body Heat

Having a cell phone is one thing, but having a dead cell phone, with a battery that's been depleted for hours even before you go out to hang out with your friends is another thing entirely. Even as smartphones evolve, their battery lives don't seem to be getting better at a rapid rate (due mostly because we use them more, thanks to the evolution of those smartphones). So, what if we could have a phone that just charged in your pocket, without us even thinking about it? That's where the Nokia E-Cu concept phone comes in.

The device would feature a small thermogenerator, that would convert heat into energy. The idea would be to be able to put the device in your pocket, and thanks to your body heat, give the device a slight charge throughout the day, whenever it is in your pocket. Theoretically, this would give the device a small charge, but it could get a big boost of energy if you were to put it on, say, a heater.

It is just a concept device, but the idea is a good one. And the design doesn't have to be so outlandish that it will never get to market. Will it show up next year? Probably not. But, there is a small glimmer of hope that a device like this could show up sooner than later.
