How about a new Nokia design based on eco-friendly technologies? Patrick Hyland created the interesting Nokia E-Cu concept, that can be charged simply by using heat. The handset integrates a thermogenerator, that turns heat into electrical energy, so while in your pocket the device can get charged.
The E-Cu name is a combo between Environment (E) and Copper (Cu) and we learn that this phone is surrounded by a copper layer with engraved heatsinks. You’ll never need a phone charger for this piece of gear, so you’ll be saving Mother Nature again. We have to say that this is quite a slim device, with a solid design and a strong idea behind it.
Let’s hope it becomes real!
