Nokia E-Cu Concept Phone – Charge Your Phone By Keeping It In Pocket
Imagine a mobile phone that you can charge simply by supplying heat to it. You can put it next to a hot source or simply let it stay in your pocket and get warm – and as a result, it will recharge. While the concept seems futuristic, it is quite possible and has been presented by designer Patrick Hyland. The concept phone has a copper-coated back-case which enables heat to be conducted more effectively to the device.
