Cellphone concept charges itself from body heat while in your pocket

Keeping a phone charged can be a pain, especially at the end of the day when you're out of the house and dealing with a sliver of battery life. If only a phone could stay charged up all day without you ever having to think about it.

That's the idea behind the Nokia E-Cu concept, a slim phone that uses an integrated thermogenerator that converts heat into energy. That means it could get a slight charge while sitting in your pocket against your leg and an even bigger charge while placed on top of a radiator.

Just how realistic is this? Probably not so realistic that you'll see this in stores next year, but I don't think it's so out of the realm of possibility that we'll never see something like this implemented. At least I hope so, as there are few things more annoying than being out and about with a dead cellphone.
