Concept: Copper Phone Uses Heat for Power
The Nokia E-Cu by Patrick Hyland is a mobile phone charged by sources of heat therefore eradicating the need for a charger. The phone has a thermo-generator integrated inside, which converts heat energy into electric potential energy. It is surrounded by copper with engraved heat sinks in a dry earth pattern which represents the effect of heat on the natural environment. The phone can be charged by placing it on any source of heat e.g. a radiator, even inside a pocket.
